Building Better Batteries

For close to 100 years inventors have been trying to put zinc into a rechargeable dell inspiron e1705 battery,dell latitude d410 battery. Thomas Edison tried and failed to tame the feisty electrode. In recent decades dozens of companies have run into electrochemical and commercial roadblocks.

PowerGenix of San Diego has achieved some initial success. In December it began selling its AA rechargeable nickel-zinc batteries in Ritz Camera stores. It now has agreements to deliver $70 million worth of its batteries over the next three years to makers of power tools, garden tools and electric scooters and bicycles; shipping starts this fall. The attraction: Zinc is plentiful, nontoxic, recyclable and enables production of batteries with a high rate of discharge.

Among the key determinants of dell latitude d420 battery,dell latitude d430 battery success are cost and weight per watt-hour stored. Zinc’s metrics: 40 cents, 17 grams. That compares with 48 cents, 25 grams for the older nickel-cadmium, and 70 cents, 9 grams for the newer lithium-ion chemistry, which is rapidly gaining ground in the power tool market and already pretty much owns the laptop and cell phone business.

Zinc’s lower cost and high discharge give it a shot at the power tool market, says PowerGenix Chief Executive Daniel Squiller, who previously ran the power supplies and battery unit, a U.K. controls and automation company. Prices are still relatively high: a four-pack of nickel-zinc AAs (storing 10.4 watt-hours) with a charger sells for $40, 20% more than a comparable nickel-metal-hydride set at Ritz. For power tools PowerGenix expects to charge less than makers of nickel-metal-hydride batteries.

PowerGenix is still a pip-squeak, having raised only $61 million from venture capitalists and praying for revenue of $10 million this year. But Squiller’s ambitions are big. There could be room for nickel-zinc in household electronics and toys as well as in drills and hedge trimmers. Nickel-cadmium, a common rechargeable dell latitude d500 battery,dell latitude d505 battery  for consumer products, is being legislated out of existence in certain European countries because cadmium is a toxic heavy metal that contaminates the environment. Last year retailer Toys “R” Us and manufacturer  swore off nickel-cadmium in toys they make.

Seeing the coming death of nickel-cadmium, PowerGenix designed its manufacturing process to work with minor adjustments on existing nickel-cadmium and nickel-metal-hydride production lines. PowerGenix is outsourcing production to a Chinese company.

How PowerGenix solved the longtime challenge of getting zinc to recharge is a tale of insight and persistence. Rechargeable batteries use positive and negative electrodes that oxidize and dissolve to varying degrees when the dell latitude d510 battery,dell latitude d520 battery  is in use or recharging and then go back to their original states. Those who tried using zinc as a negative electrode found it tended to drift around during discharge and not return to its original location during recharge, quickly rendering the battery useless.

PowerGenix solved the problem over two years by using an electrolyte–the electrically conductive material in the battery–made with a small amount of phosphate. The phosphate limits the zinc’s solubility so the battery can recharge. PowerGenix chemists also found they could retard the faster corrosion rate of the higher-voltage zinc batteries by using purified zinc.

AMD News: Notebook Battery Life Claims are Bogus

AMD isn’t happy with the way some dell inspiron e1405 battery,dell inspiron e1505 battery claims are made, saying the reliance on a test called MobileMark 2007 doesn’t yield an accurate indicator of what to expect.

 The problem, says Patrick Moorhead, a vice president for marketing at AMD, is that the parameters for the test include dimming the screen the just 20 percent brightness, turning off WiFi, and making sure no music, video, games, or webpages are running. Not only is the test flawed, says Moorhead, but it also favors Intel.

“Intel is advantaged in this environment because they have optimized their architecture to have bettery battery life when the computer isn’t doing anything,” Moorhead said.

Intel shrugged off AMD’s complaint, saying if the No. 2 chip maker is so passionate about the subject, it would “encourage them to bring any new proposals or edits to the nonprofit industry dell inspiron e1705 battery,dell latitude d410 battery consortium called BAPCo.”

But is AMD out of line? Not likely. In the June issue of Maximum PC, Editor-in-Chief Will Smith discussed the topic in his Ed Word titled “Notebook Battery Life is a Trap.”

“You’d think testing battery life would be straightforward, but benchmark results rarely jibe with real-world results — in part, because there are an infinite number of potential workloads (each tapping power differently), and   battery life decays over time,” Smith wrote.

AMD warns that either the industry dell latitude d420 battery,dell latitude d430 battery starts better regulating itself, or there’s a high possibility of a consumer filing a lawsuit or the FTC stepping in.

New type of polymer lithium-ion battery successfully developed

New type of polymer lithium-ion battery successfully developed

With independent intellectual property rights of a new type of polymer lithium-ion battery R & D success of a few days ago and will soon be put into the production process of industrialization. According to Science and Technology Daily reported that this unique battery technology is from 4 years ago returning from overseas, led by its researchers Following the liquid plastic film lithium-ion power batteries made after the outcome of an important. At present, the polymer lithium-ion battery production lines are under construction.

It is understood that the liquid lithium-ion battery is the most high-tech research in recent years one of the important results, representing the current development of the chemical power of the most advanced level. As a result of such batteries with high specific energy and recycling, the good life, such as a significant advantage, now widely used in mobile communications, cameras, laptops and other electronic devices, and is gradually moving towards electric bicycles, electric vehicles and other areas to expand the scope of application. It is estimated that the global lithium-ion dell battery demand has reached 1.3 billion, and with the applications and the ever-expanding year by year.

In liquid lithium-ion battery at the same time the successful commercialization of polymer lithium-ion battery (PLIB) research has been particular concern to them. As a new generation of lithium-ion battery system, PLIB not only with liquid lithium-ion battery all the technical advantages, but also has a higher specific energy and better safety performance. In addition, PLIB is recognized as the most development potential and future application of the battery market products. It is predicted that in the next few years, PLIB will replace the liquid lithium-ion batteries for nearly 50% market share, there are broad prospects for the development of Japan and many other major battery makers focus on R & D investment and the direction of.

The past, both at home and abroad polymer lithium-ion battery manufacturers use the United States Bell Laboratories Bellcore process. However, due to the cumbersome process of the method, low efficiency, investment in equipment and the shortcomings of higher cost of production, serious constraints of polymer lithium-ion battery development and industrialization. Domestic and foreign markets in recent years in the so-called polymer lithium-ion battery products, but in fact is a flexible liquid batteries, there are still a large number of internal dynamic electrolyte flow, do not have the characteristics of polymer electrolyte, in the security risk there. With lithium-ion battery in the communications and IT industry’s rapid surge in usage, the battery safety performance is increasingly prominent, not only the requirements of lithium-ion battery has excellent electrical properties, also called for greater security.

CITIC Beijing UNITA solid profits and new material technology, Beijing Institute of New Energy Materials and Technology Laboratory, through years of research, in a large number of laboratory work on the basis of a number of key materials through an integrated technology, the first synthesis of a unique structure microporous polymer composite membrane, and then use a unique production process of polymer batteries developed a polymer lithium-ion battery. The battery has a very excellent low-temperature discharge performance and cycle performance (over 500). With the same battery capacity compared to liquid packaging, such polymer lithium-ion rechargeable battery and acupuncture in the past, such as safety testing, in particular, a unique performance advantages. Importantly, by researchers and development of new polymer lithium-ion battery production technology, also has a small investment in equipment and production technology is simple and so on. The results with independent intellectual property rights, there is no doubt China will enhance battery manufacturing sector in the international competitiveness and promote domestic polymer lithium-ion kd476 battery, td347 battery, dell inspiron 1501 battery industry and greatly expand the lithium-ion battery applications.

U.S. R & D of micro-generators to replace the phone battery

Recently, the USA and Georgia Institute of Technology announced that with the Massachusetts Institute of Technology, working closely with scientists, they have successfully developed a micro-generators, only 10 mm in diameter, is the continuing use of mobile phone battery is more than 10 times.

Over the years, more and more compact electronic products, and its battery has a larger volume of plays. In order to solve this problem, the scientists have been dedicated to the development of micro-generators, and put forward a number of different principles of micro-generators. And the Georgia Institute of Technology scientists have developed such a generator to replace the phone battery, indicating that micro-generators to enter the electronic products to replace conventional batteries and an important step.

The principle of the micro-generator is installed in a chip on the induction coil, so that a small rotating magnet around the coil, resulting in sufficient current. Through continuous testing, the rotating speed of the magnet is now up to 100,000 per minute lap, the speed can generate 1.1 kilowatts of electricity, enough to replace the phone battery.

Fuel cells should be the development of new energy in the success of

A few days ago, by the four home appliances and accessory factories in Dalian Institute of Chemical Physics, Chinese Academy of Sciences to develop the national “863″ the new fuel cell energy projects successful “out” next year will be in volume production in May.

It is reported that the fuel cell using hydrogen and oxygen in the air a chemical reaction and generate electricity and hydrogen with a drive more than three hundred kilometers. Compared to conventional fuel energy, it has a high rate of energy conversion, less environmental pollution, etc., which is considered the first choice of 21 clean, efficient, clean energy. This will not only fuel cell electric vehicles in use, but also for submarines and other military equipment, have good market prospects.

Power grid investment imbalances appear contradictory

China’s electricity supply situation in 2005 as follows: lack of electricity is reduced, the degree of ease power shortage, the largest gap from 12 to 20 million kilowatts, seasonal power shortages, electricity supply shortages apparent randomness; power grids and power imbalance between investment contradictions begin to be felt.

Ouyang Changyu said, according to a preliminary statistical analysis of production units in 2005 more than 68.4 million kilowatts, of which 23.8 million kilowatts during the first half of production more than the end of power generation capacity of more than 510 million kilowatts. Electricity shortage in recent years against a background of a lot of money into the field of power construction, signs of a new round of power surplus, the imbalance between investment in the power grid began to gradually expose the contradictions. If the project can not be put into production on schedule or electricity supply problems are not solved, is even more serious power shortage.

Ouyang Changyu, said in 2005 should attach great importance to investment in power grids and power imbalances, do everything possible to increase power grid investment. Study suggested that the state departments concerned to speed up the market mechanism to play a fundamental role in the macro-control mechanism for project construction as soon as possible the establishment of a unified power grid and power planning, coordination mechanism for development.
