Characteristics of VRLA batteries work

From the electrochemical reaction can be seen, thebattery discharge, dell laptop battery the cathode must have a molecular weight 1 grams of lead dioxide, Anode 1 grams must have a molecular weight of the sponge-like lead, at the same time it should have the molecular weight of 2 grams of sulfuric acid involved in the discharge process to be carried out smoothly. Use of Faraday Faraday's Law constant, electrochemical reaction through the above-mentioned formula, the calculation was informed that: lead dioxide electro-chemical equivalent of up to 41.46g / from, cavernous lead for electro-chemical equivalent 33.87s/Ah. That is to say: VRLA battery to produce electricity hours 1 amps, the cathode must have 41.46g of the active material of lead dioxide at the same time must have a negative lead 33.87g cavernous sufficient amount of active substance in the presence of sulfuric acid in order to do so. VRLA battery to produce electricity 100Ah, the cathode must have a lead dioxide 4146g, 3387g have a sponge-like negative electrode lead 417066-001,hstnn-lb31,411462-421,hp pavilion dv2000 battery can be achieved.



Note from the principle on which the battery capacity is why the quality of the number of active objects to determine the truth. This is also the user to buy the battery, why that big battery weight than the weight of the batteries of their good quality root cause of the problem. Of course, here are listed in electro-chemical equivalent of a theoretical value only. In addition to VRLA batteries have lead-acid batteries with the opening of the electrochemical reaction in the same manner as the same working principle, it also has a lead-acid batteries and do not speak the same principle, that is, cathode absorption principle, the so-called principle of the cathode refers to the absorption cell when in charge, especially in the late charge, cathode will have oxygen, because of VRLA battery is sealed, the gases produced by the battery will not be as open as at any time and can be distributed through the openings to the cells in vitro to produce the gas in the battery the accumulation tank. With the battery inside the gas volume of the accumulation of increasing pressure on the internal battery to increase gradually.Dell Inspiron E1505 Battery It is precisely because of the existence of the internal battery within a certain pressure, the oxygen cathode will have to go negative on. Since the cathode is generated by the oxygen atoms, while the oxygen atom also has a strong oxidizing, which has strong oxidation ability of oxygen atoms to go negative,Dell Inspiron E1505 Battery, Dell GD761 Battery, Dell KD476 Battery, Dell TD347 Battery
Dell Inspiron 1000 Battery, the negative electrode in the charge will be generated when the gang activity also have a big sponge symptoms of lead oxide and lead oxide generation, lead oxide and then with sulfuric acid to form lead sulfate and water, sulfuric acid is the negative lead is the product of discharge, lead sulfate when in charge of lead generation cavernous, cavernous lead again generated positive absorption of oxygen and lead oxide to generate such a repeated cycle of the reaction of oxygen to produce positive were negative absorption, and no matter how oxygen generated will not be charging, the battery internal pressure will not continue to rise, more battery will be no need to worry about the explosion occurred hp pavilion dv6000 battery, hp pavilion dv2500 battery.



In order to prevent the special circumstances in the internal battery gas accumulation due to increased internal pressure caused by the battery explosion, in the design, and specifically in the cell above to set up a safety valve, when the battery internal pressure reaches a certain value, the safety valve will automatically open to release a certain amount of gas to reduce pressure, the safety valve will automatically shut down. Above, is the cathode battery Ⅷ IA absorption principle. It is precisely because of the discovery and invention of the cathode cell to absorb this principle, it can be made open-wide lead-acid storage battery sealed, VRLA battery was able to come out.

Of course, the VRLA battery to absorb the principles of the cathode can be maintained, Dell KD476 Battery, the first prerequisite is that the battery must be sealed, not sealed, the battery does not exist within a certain pressure, the oxygen generated on the cathode can not go negative absorption was negative , oxygen will run out and run away would be tantamount to oxygen water off the internal battery, and battery water loss, it should pay, will not need to pay a call VRLA batteries, it becomes open the battery. It can be seen, VRLA battery is good or bad sealing performance is a key technical indicators, the user in the selection of the battery should be attached great importance to this issue, even a little bit of gas leakage or fluid, will be a direct impact on battery life life. If the battery pack in such a battery, this battery will become the first affected by the battery behind the whole performance of the battery pack, battery pack could cause the battery voltage in the non-balanced and a vicious cycle.

As we all know, VRLA battery (VRLA battery) is also a lead-acid batteries, since it is lead-acid battery, it should have open-type lead-acid batteries with the same working principle. This means that the battery VBLA to achieve energy conversion and energy storage of the carrier with the openings of the same, its participation in the electrochemical reaction is the same material and are in charge, the positive lead from the sulfuric acid (PbSO4) into lead dioxide (Pb02) after chemical energy into electrical energy stored in the cathode plate; negative lead from the sulfuric acid (PbSO4) lead into a sponge-like (spongy Pb) will be converted into chemical energy stored in the anode plate. In the discharge, the cathode by the Lead Dioxide (PbO2) into lead sulfate (PbSO4) will convert chemical energy into electrical energy to the load power supply,Dell TD347 Battery negative lead from the sponge-like (spongy Pb) into lead sulfate (PbSO4) and will chemical energy into electrical energy supply to the load. Of course, it will definitely have positive and negative at the same time from the same state with the equivalent (such as charged or discharged state) can be achieved for the electrochemical reaction of charge or discharge the above-mentioned process, at any time under any circumstances can not be separate from the cathode or anode alone to complete the electrochemical 367759-001,hstnn-ib09,hp pavilion dv1000 battery reaction of the above.



It can be seen that if Chiang Kai-shek a battery plate is good, the bad and the negative plate, then there would be equal to this battery into a battery of end-of-life. Similarly, if a battery of negative plates is good, the bad and the positive plate, then, this battery can only be a battery of end-of-life. In addition, the positive plate in the energy conversion can take part in the quality of the material (the amount of active substance) and the negative electrode plate can take part in the complex energy conversion quality (the amount of active substance) to match each other. If you do not match more than one, a small, part of the multi-out is a waste, but also to participate in each of the electrochemical reaction with another material to match the amount of material is different to each of the scientists material can be one amps-hour of electricity (from a) into chemical energy stored in the volume of the substance known as electro-chemical equivalent (that is, power and chemical energy conversion of a considerable amount of material). Dell Inspiron E1505 Battery, Dell GD761 Battery, Dell KD476 Battery, Dell TD347 Battery
Dell Inspiron 1000 Battery, Each of the active substances of equivalent power by electrochemical reactions are calculated formula. The above-mentioned principle of lead-acid batteries of all content (including electro-chemical equivalent) with the following electrochemical reaction hp pavilion dv4000 battery , hp pavilion ze2000 battery , Dell Inspiron 1000 Battery hp presario m2000 battery , hp presario v2000 battery can be expressed as Formula: PbO2 + Pb +2 H2S04 ← → 2PBS04 +2 H20

Expo Science and Technology for laptop battery

2009 China International Industry Fair will be opened. As in previous years, this Industry Fair covers the hot technology in today's world, brought together toshiba batteryChinese and foreign industry leaders, highlighting the modern industrial world-class advanced equipment manufacturing industry and China's new achievements. IBM Laptop Battery However, this year's so special is that the 2010 Shanghai World Expo will be applied in a number of scientific and technological innovation and significant achievements, but also will act together in public appearance at Bo. "Better City, Better Life; science and technology, so that the Expo even more exciting." Reporter walked into the Shanghai New International Expo Center, Hall W1, preview, "the Expo Science and Technology Exhibition."

New Energy: a generator house

This session of the Industrial Fair, the "new energy" will be a rehearsal for the World Expo.

Expo park, we will take alternative modes of transport travel? This reporter learned that,IBM ThinkPad A20M Battery, IBM ThinkPad A21M Battery,
IBM ThinkPad R60 Battery, IBM ThinkPad T60 Battery, .. 28 square kilometers inside and outside the Expo area will be used thousands of units of new energy vehicles to provide transport services to achieve Expo passenger transport area "zero emissions", the park around the realization of the traffic, "low emissions" goal. Hybrids, pure electric vehicles, fuel cell cars ... ... Hall in the W1 "green transport" exhibition, a large, innovative, ahead of the new team bring people into the new energy sector.

At first glance, these new energy vehicles and ordinary cars look no different, that they are exactly how to run it? It turned out that the "secrecy" in the car. Such as fuel cell vehicles, they are drinking is not "gasoline", but "hydrogen",IBM ThinkPad A20M Battery which are mostly hydrogen re-use of industrial by-products, but also low-cost and environmentally friendly. The presence of engineers, told reporters during the World toshiba PA3191U-2BRS battery， toshiba PA3191U-3BRS battery，， Expo, over 190 vehicles, hydrogen fuel cell vehicles need to 604 kilograms per day in order to ensure the supply of hydrogen, the exposition will be built near a hydrogen refueling station, and two mobile hydrogen refueling station and the current Anting, together with the formation of hydrogen filling station network.

Of new energy technologies is not only used in transport, has also been used in the exposition area of the buildings. Such as building-integrated photovoltaic technology, solar photovoltaic panels made of building materials, so that the building facades, roofs become a "generator", and will produce electricity grid enter a city power grid, so that the "green electricity" to enter millions of households. The technology in the Expo area to achieve a large-scale application --- the World Expo will be a total installed capacity of photovoltaic construction project is 4.5 MW, is currently a single park in China even in Asia's largest building-integrated photovoltaic grid power system .

Have heard of those cars are not only energy consumption, or "generation who" do? Smart grid make it all possible. Siemens electric cars on display "GREENSTER" is a typical example, it is not just an environmentally friendly means of transport, more as a mobile electrical storage devices, the power to re-transfer back to smart grid.IBM ThinkPad A21M Battery Similarly, the building energy consumption in the past, those who are, but if access to the roof of photovoltaic power generation smart grid, the house can also become generators.

Shanghai urgent need to vigorously promote the new energy vehicles,IBM ThinkPad A20M Battery, IBM ThinkPad A21M Battery,
IBM ThinkPad R60 Battery, IBM ThinkPad T60 Battery, but the difficulties encountered is the lack of hydrogen refueling station matched, while the pure electric cars need to have charging facilities Curry family cars. In addition, the solar energy toshiba PA3284U-1BRS battery，toshiba PA3285U-1BRS battery， toshiba PA3285U-2BRS batteryin fact is not the key technical issues, photovoltaic power generation, wind power and other renewable energy power only through a sophisticated intelligent grid to transmit in order to stabilize the. The Engineering Fair for display of these new technologies, combined with the application of the 2010 World Expo, showing a viable exploration, which is more important than the advanced technology.

New Ecology: Garbage by pipeline

Green from the park to the harmonious ecological environment, from the safety of drinking water into the atmosphere, water and solid waste pollution control, from venue construction to the construction of environmental remediation harmless waste treatment and resource utilization of the ... ... Bo at work, demonstrating the Expo's "ecology and environment" system.

"In Shanghai Eco-Home" is very eye-catching.IBM ThinkPad R60 Battery As the Shanghai World Expo Shanghai Urban Best Practice Area only kind case, "in Shanghai Eco-Home" show home construction on the ingenious use of renewable energy. Industry Fair a live demonstration of "eco-floor" model: the roof of a huge solar thermal equipment, power generation, not only for the whole building, but also with the urban grid through grid-connected, if there is surplus energy, can supply the entire power grid use, such " Eco-House "has become a small power plant. In addition, wind power, clean energy, fuel cells, are all recyclable material has been applied in the floor. The most interesting is a display of old bedroom. Remote medical sensing applications, makes the family doctor is not around, you can learn the old bed of blood pressure, heart rate, and other signs, this is undoubtedly an aging society should be resolved. "Perhaps this could be a reality in 2030." Staff said.

Public Bo was also displayed at the Expo will be an integrated water resources management, environmental protection concepts from the "water source" to infiltrate "taps." Look at the water source, currently under construction, grass sand water source of raw water project, the city will make about 70% of the water into the Yangtze River water quality. Then, the collected water will be toshiba PA3285U-3BRS battery，IBM ThinkPad A20M Battery, IBM ThinkPad A21M Battery,
IBM ThinkPad R60 Battery, IBM ThinkPad T60 Battery, toshiba PA3383U-1BRS batterycarried out bio-ecological restoration of water bodies. Industry Fair site had an interesting demonstration of this: a similar fish tank containers filled with algae and other biological. The staff said that through soil purification, biological purification, purification plants,IBM ThinkPad T60 Battery and zeolite purification, etc., will be worse than the Huangpu River Ⅴ - Ⅴ type of water, into a landscape Ⅱ type of water, the process only 2-3 days. Finally, in the "tap" that hurdle, and will go through a water supply network of digital information platform for real-time monitoring efforts to ensure water safety.

Expo will be how to deal with garbage? News sites, we saw garbage pneumatic conveying system is very advanced. No manual collection, was put into the mouth of indoor and outdoor garbage garbage automatically turn into the pipe, pneumatic conveying, arrived at the compressor stations, after a separation, compression, filtering, purification, deodorant, etc. and eventually routed to outdoors. The core area for the Expo will provide services.

Plan not keep up your laptop battery

Six months ago, a sharp drop in polysilicon prices in. This because they do not rely on silicon raw materials, and therefore have a cost advantage of thin-film battery experience Sheng Sijie - polysilicon from 2008 before the financial crisis in nearly 500 U.S. dollars / kg rapidly powerbook batteryfell to 60 U.S. dollars / kg price, polycrystalline silicon cells cost will be substantially reduced. At that time, Zhengrong Shi, IBM Laptop Battery chairman of Suntech has asserted that thin-film batteries will be difficult, and competition in crystalline silicon cells, thin-film batteries investment bubble will be broken.

However, six months after the thin-film solar cell business roller coaster ride once again seems to come to High Point: With the polysilicon price stability, the state's low-end polysilicon capacity, redundant construction to control the beginning of thin-film battery technology their progress is driving a new round of investment and construction boom.

"State of the polysilicon control, and certainly opportunities for thin-film batteries, thin-film battery production enterprises need to do is improve the conversion rate, opening up a bigger market." IBM 02K6651 Battery, IBM 02K6928 Battery, IBM 02K6620 Battery, IBM 02K7039 Battery
IBM ThinkPad X60 Battery,Austrian Solar Energy Co., Ltd. The new manufacturing center in Hong-Wen Li, general manager of the "China Business, "told reporters.

"Three years later the world will be a thin-film batteries." A manufacturer of thin-film batteries, Zhejiang, the case projections.

Overall warmer

October 23, the new Austrian Duke Energy Group and the United States officially signed in Hebei Langfang photovoltaic energy cooperation agreement. IBM 02K7039 Battery core content of the agreement the two sides will establish a joint venture company registered in the United States, each holding 50% stake in the common effort for photovoltaic power plant construction, building-integrated photovoltaic projects (BIPV) and other businesses.

"North America is the world's largest solar energy market, Duke Energy is the nation's third-largest electric utility holding company in the United States covering 110 million people with a rich marketing resources. The new Austrian solar cell components with the production and installation of an integrated its own characteristics, the future will be the joint development of large-scale solar power plants. "Xinao Group Vice President, the new Austrian photovoltaic CEO Hong Cai autumn on the" China Business "told reporters.

As the few companies manufacturing thin-film solar cells, one of the new Austrian now has a world-class super-large 5.7 square meters of silicon-based thin-film solar panel production line, mass production has been achieved in June this year. It is reported that this thin-film solar cell production line a capacity of 70 MW, products, photoelectric conversion rate of 9% in the next 2 ~ 3 years will be increased to about 12%.

"And the Duke energy cooperation, it is because we are optimistic about the development of photovoltaic industry. The U.S. government after the change of state subsidies for new energy sources will be gradually introduced, and from the United States power generation apple A1175 battery， apple A1185 batterysystems, distributed energy applications has been widely , large-scale solar power plants have a lot of space. "Hong Cai Qiu said.

A new Austrian told reporters that sales staff to accelerate the opening up of overseas markets due to PV from overseas orders in August after the clear signs of warming,IBM 02K6620 Battery while the demand for low-cost thin-film batteries on the rise.

An analysis of the industry, told reporters, thin-film battery industry as a whole is now warming, which ushered in a good development opportunity for two main reasons: First, polysilicon prices stable at 60 U.S. dollars / kg from top to bottom, should not have a greater decline, which makes crystalline silicon cells and thin-film batteries, there is still difference between the thin film battery still has about 20% of the cost advantages; the other hand, September 29, the State Council issued "on curbing overcapacity in some industries and redundant construction to guide the healthy development of industry, a number of opinions "on the right polysilicon industries stringent regulation,IBM 02K6651 Battery, IBM 02K6928 Battery, IBM 02K6620 Battery, IBM 02K7039 Battery
IBM ThinkPad X60 Battery, from the pollution, and capacity constraints in areas such as objective to form a thin film battery of good news.

"Thin-film battery developed rapidly in 2007, its global market share was 12% in 2008 to reach 15%, this year may reach 20%." Zhejiang Chint Solar, general manager of Yangli You on the "China Business" reporter说. According to Yang, at present, Chint's investment in solar cells for nearly 20 billion yuan,IBM 02K6651 Battery China's first trial production of 20 megawatts of thin-film amorphous microcrystalline battery production line, and its conversion rate also reached 9.2%.

According to report, more than 30 more than the current domestic production of enterprises engaged in thin-film batteries, imported equipment from abroad, nearly 20 of these to introduce the production line every capacity of about 40 MW, the average import price of 100 million U.S. dollars, of which the introduction of the new Austrian Applied Materials Inc. of the United States a product line have spent nearly 14 billion yuan.

"In the Golden Sun engineering, solar roofs under the influence of policies, in addition to overseas markets, China's future is certainly an emerging market."apple M8403 battery Applied Materials Solar Energy Corporation CEO Charles Gay on the "China Business" reporter, said a few days ago, the United States Applied Materials R & D center in Xi'an just been completed, which also includes a thin-film solar panel production line.

"Sunny future of China's western region sales of solar batteries, the battery compared to the thin-film crystalline silicon cells, its has the low light intensity, low-cost advantages such as resistance to adverse weather conditions better suited to the western region, which a rigid thin-film batteries will stimulate demand for the rapid development of the whole industry. "Charles Gay says.

Risks remain

However, the prospects for thin-film batteries is not a smooth sailing.

According to report, on the current international industrial production of thin film batteries are mainly three kinds, namely, silicon-based thin-film solar cells, copper indium gallium selenide thin-film solar cells (CIGS), cadmium telluride thin-film solar cells (CdTe). IBM ThinkPad X60 Battery,Of which domestic enterprises are mainly doing the first two, the latter technology has been monopolized by the U.S. company First Solar.

"Finally a technology, the U.S. First Solar's conversion rate can reach about 11% is already the highest level in the field of film, but even so, conversion rates vary with the crystalline silicon cells for more than half. Suntech is currently the crystalline silicon cells conversion rate has reached 19%, the world's most advanced crystalline silicon cells reached 22% conversion rate,IBM 02K6651 Battery, IBM 02K6928 Battery, IBM 02K6620 Battery, IBM 02K7039 Battery
IBM ThinkPad X60 Battery, thin-film batteries in a short time is difficult to compete with crystalline silicon cells. "Great Wall Securities analyst Tao Zhou told reporters.

Zhou Tao, due to the development of thin-film batteries a short time, a number of large general-purpose production equipment capable of manufacturing the world is only three, namely the United States, Applied Materials (AMAT), Switzerland's Oerlikon (Oerlikon) and Japan's ULVAC ( ULVAC), such as new equipment is the Austrian Applied Materials imported from the United States, while the Chint is imported from Oerlikon. The production equipment is very expensive.

How to purchase a second laptop battery ?

Notebook battery is the "power source", especially for those who often walk a friend, in addition select models with the ultra-long standby selling point, the timely preparation of a second battery is an urgent task. Meanwhile, the laptop battery is also a consumable, general use IBM Laptop Battery batteryin 2012 will be significantly decreased after the performance, coupled with some users usually do not pay attention to battery maintenance work, the battery performance,IBM FRU 92P1167 Battery, IBM ThinkPad Z60t Battery, IBM ThinkPad Z61t Battery, as well as the rapid decay of the examples of early retirement are not uncommon. Ran Unfortunately, the growing demand today, the battery market has not subsequently be further standardized. Not only the renovation, the phenomenon of counterfeiting occur from time to time, that is, original manufacturers, even in the same series There is also a man-made obstacles set up. And electoral laptop compared to the choice of the battery does not to mention easy!

A look at parameters

As the laptop battery is not universal, consumers must be masters of our own before buying the machine can accept the battery type, and in order to avoid being cheated, in the "look", the right not to relax the inspection of workmanship!

Currently, in addition to individual low-end notebooks use nickel-metal hydride batteries, most are used in ordinary lithium-ion batteries, lithium polymer batteries only in part the use of high-grade ultra-thin notebook. Lithium batteries are generally batteries Unit to protect the circuit and capacity for monitoring and communications circuit of several components. From the perspective of the parameters, the battery capacity is an indicator of concern. Now generally 3000 ~ 4500mAh, there are very few with a 6000mAh capacity. In theory the higher values in the same configuration using the longer.

The manufacturer of the laptop battery has a more detailed description, we often can see the "six-core 4400mAh", IBM FRU 92P1167 Battery,"4-pin 2200mAh" nominal value such as batteries, over time, we believe that directly determines the capacity of 4400mAh or 2200mAh laptop working hours. In fact, we talk about computer power consumption, the total nominal power use, rather than simply current. The battery power should be multiplied by current, voltage to the common 2200mAh, 3.6V batteries, for example, could have used some small way the composition of four batteries in series, their voltage is 14.4V, Capacity 2200mAh. Many 14-inch notebook, you might use 2 and 4 strings of 8-cell hybrid mode, the voltage remains at 14.4V, capacity doubled to reach 4400mAh, to ensure a longer usage time. However, the same is a 2200mAh, 3.6V batteries, if we adopt the 2 and 3 sony VGP-BPS2 battery strings of 6 cores hybrid approach,IBM FRU 92P1167 Battery, IBM ThinkPad Z60t Battery, IBM ThinkPad Z61t Battery, its battery capacity it will still be 4400mAh, voltage down to 10.8V, if we just look at capacity, its use of time should be, and 8 the same cell battery. If you press power, then it 8-cell lithium battery, the power should be 63.36Wh, 6 cores for 47.52Wh, 4 cores for 31.68Wh. If according to this value, the advantages of 8-cell lithium battery can be reflected.

Appearance, the general assembly of the battery shell mold is not original battery specifications, so loaded notebook computer will appear to take difficult or loose loaded situations; assembly of the battery is not original battery plate production print quality is good, writing and more rough is not clear, in any encounter when buying this kind of "original battery" would not buy. In addition, the renovation of the distinction between products and new battery is still in its electrode wear traces of heavier and therefore does not gloss and new batteries, buy encountered in the so-called "new batteries" do not buy.

Comment: Taken together, apart "6-pin 4400mAh" this parameter, the battery voltage is also a need to know the parameters.IBM ThinkPad Z60t Battery From the application point of view, low-voltage large-capacity battery (more parallel, less in series) to ensure the laptop longer standby time, while the battery is almost no additional cost!

Second, weigh the quality of

Very often, the quality of both the power and weight proportional, laptop batteries are no exception. As the original battery protection circuit are doing more monitoring in place, the quality is better on batteries, so the weight of the assembly of the battery than the jerry-building is much greater when you buy them by hand Dian Dian, if compared with the original laptop battery light a lot of words Such batteries need to be careful!

As the recent past, Dell, Apple, Sony, Lenovo and other laptop caught fire after another, making the image of the original battery much frustration, but overall the quality of original equipment batteries, or more outstanding. So I believe that choice should be based on a second battery or original products. Of course, the market compatible with many types of cells, some with the original brand notebook chip and the IC design and manufacture of high-quality batteries, not only have all the original battery protection, and stable performance, IBM FRU 92P1167 Battery, IBM ThinkPad Z60t Battery, IBM ThinkPad Z61t Battery,use of time is relatively long, the actual performance with the original battery is not much difference; but some small workshop production of The quality of the compatibility of the battery is not flattered, and the battery's sony VGP-BPS2A battery internal circuit design is extremely simple and the quality of batteries used in more times, and some have even adopted disassemble or brand-name batteries, this battery is compatible with the quality of the natural is not guaranteed; In addition, some laptop batteries inside the original battery failure,IBM ThinkPad Z61t Battery a number of business through self-change batteries way for original equipment batteries to obtain a "new life." However, this time piece of the battery is not the true sense of the original battery, but rather are compatible with the battery, its quality depends largely on how the quality of batteries. So, is compatible with the battery whether it is worth buying, in addition to the price, the key is to see how its quality. For those who are from small workshops compatible battery, even if the prices are a great advantage, not worth buying.

How To take care your dell laptop battery?

Wires, batteries will soon be things of past

more batteries, no more chargers and no more wire spaghetti. This is the future promised by "wireless power", a means of broadcasting electricity through the air to laptops, iPods and other gadgets without the need for cables and sockets.

Untethered lighting, audio speakers and digital picture frames are expected to be among the first commercial products demonstrated in Las Vegas this week at the International Consumer Electronics Show, the world's biggest gadgets tradeshow.

Experts believe this is just the beginning and Toshiba PA3506U-1BRS Battery that eventually wireless electricity - dubbed "WiTricity" by some - could do for battery life what WiFi did for the Internet. In a world without wires, laptop users in cafes and airport terminals would be inside an "electricity hotspot" and no longer have to delve past legs, bags and furniture in search of an awkwardly located socket.

"You'd be able to buy a desk that charged any gadget placed on it, or power any PC you put on top," said James Holland, editor of gadgets website Electricpig.co.uk.

"If each room had wireless power, you'd know that once you walked through the front door your mobile would start charging up - even while still in your bag or pocket. You'd never need to hunt for the right charger again."

Among the companies showcasing the ambitious technology at CES is PowerBeam. Its system Toshiba PA3291U-1BRS Battery turns electricity into an invisible laser, then literally beams it, as heat, across the room to a solar cell that converts it back into electricity.

David Graham, the co-founder of PowerBeam, said: "We're going to delete the word 'recharge' from the English dictionary. If your cell phone is recharging on your desk all day, you won't be thinking about it."

The Silicon Valley company can currently use a laser to generate about 1.5 watts of power to a solar cell 10 meters away. This would be enough to power an electronic speaker or small LED lights, but not enough to operate a laptop, which requires an estimated 30 to 50 watts. However, Graham said that the technology could comfortably be scaled up.

PowerBeam insists its laser does not pose a risk to users' health because it is simply moving heat from one place to another. Graham said that, if someone walked through the beam, it would shut down within a thousandth of a second, then restart once the path is clear. The technology also promises energy efficiency because it would only power products when needed.
