Batteries and News

As  HP Compaq Business Notebook NX6300 Series Battery    go, the rechargeable lithium-ion variety is among the greenest options available. They can last for years, they are recyclable, and they don’t contain the toxic heavy metals found in many of their Walkman-powering predecessors.

At this point, the authors calculate, the primary limiting factor is no longer storing lithium in the Toshiba Satellite M200 Battery ; instead, getting the lithium in contact with an electrode is what slows things down. The electrodes also become a problem because they need to occupy more of the volume of the Laptop Batteries   in order to maintain this rate of charge, which lowers the charge density. That’s a major contributor to the halving of the battery’s capacity mentioned in the previous paragraph.

Ross Dueber, the company’s chief executive, says a top-tier laptop manufacturer will release the first computer designed to accept silver-zinc batteries in mid-2009. The laptop’s runtime with silver-zinc will increase from the roughly 5 hours afforded by a typical lithium-ion battery to at least 7 hours, according to Mr. Dueber.

The results are pretty astonishing. At low discharge rates, a cell prepared from this material discharges completely to its theoretical limit (~166mAh/g). As the authors put it, “Capacity retention of the material is superior.” Running it through 50 charge/discharge cycles revealed no significant change in the total capacity of the  HP Compaq Business Notebook NX6310 Battery.

In terms of the environment, ZPower has been touting its silver-zinc   Toshiba Satellite M100 Battery     as 95 percent recyclable by weight and containing no heavy metals or toxic chemicals. Still, silver is regulated as hazardous waste by the Environmental Protection Agency and can be harmful to aquatic life. So ZPower’s claim to greenness may depend largely on whether it can successfully entice customers to recycle.

A more significant problem is that these batteries may wind up facing an electric grid that was never meant to deal with them. A 1Wh cell phone battery could charge in 10 seconds, but would pull a hefty 360W in the process. A battery that’s sufficient to run an electric vehicle could be fully charged in five minutes—which would make electric vehicles incredibly practical—but doing so would pull 180kW, which is most certainly not practical.

ZPower says its batteries don’t explode. (Image: ZPower)“If ZPower follows through and does the materials recycling, that would be a significant improvement, because that’s not currently what happens if you recycle a lithium-ion battery in the United States,” Mr. Harrell said.

In the race to make the lithium-ion batteries that will run the electric cars of the future, the United States is losing to Asian countries, and start-ups and big companies need to band together to build a lithium-ion battery industry in the United States, says Jim Greenberger.

In spite of this success, don’t look for PowerGenix brand  HP Compaq Business Notebook NX5100 Battery   to be on sale at your local Radio Shack or under the hood of a Toyota Prius anytime soon. While the company already manufacturers their NiZn cells for use in power tools, electric scooters, electric bikes, and for companies selling rechargeable AA and AAA   Toshiba Satellite U200 Battery    (check out the NiZn cells at Ritz Camera), PowerGenix has opted not to create a brand name for their    Laptop Batteries  (they don’t want to take on the big-spending bunny). Regarding automotive applications, PowerGenix plans to license their technology.

When NiMH was first introduced there was much publicity about its memory-free status. Today, it is known that this chemistry also suffers from memory but to a lesser extent than the NiCd. The positive nickel plate, a metal that is shared by both chemistries, is responsible for the crystalline formation.

The new technology comes from the California company PowerGenix. The company holds 23 patents (granted and pending) on Nickel-Zinc batteries. The base formulation for NiZn batteries isn’t new (Thomas Edison attempted but gave up on making the formulation work), but as PowerGenix CEO, Dan Squiller noted, “What the engineers and chemists at PowerGenix discovered was how to make the elements play nice together and last for an extended period of time while charging and discharging.”

The problem with the nickel-based battery is not the cyclic memory but the effects of crystalline formation. There are other factors involved that cause degeneration of a battery. For clarity and simplicity, we use the word ‘memory’ to address capacity loss on nickel-based   HP Compaq Business Notebook NX6100 Series Battery  that are reversible.

Detroit Janyuary 14, 2009; Surprisingly, it’s been nearly two decades since the last major advance in battery technology. For non-geeky battery types, this would have been the commercialization of the Lithium Ion cell. This Toshiba Satellite P200 Battery    type remains the industry’s standard for pure electric vehicles because it can deliver more power over a longer period of time at a lower cost than any competitive technology.

Lithium and lead-based batteries are not affected by memory, but these chemistries have their own peculiarities. Current inhibiting pacifier layers affect both batteries — plate oxidation on the lithium and sulfation and corrosion on the lead acid systems. These degenerative effects are non-correctible on the lithium-based system and only partially reversible on the lead acid.

According to Squiller, the company’s batteries will be used in automotive applications (HEVs) in the foreseeable future, but probably not sooner than 2011 models. “We expect that HEVs will become a standard of sorts in the next few years,” Squiller said as he referenced the expansion of the “auto stop” feature on vehicles with standard internal combustion engines. “These vehicles represent the perfect application of Nickel Zinc battery technology, because they need bursts of power for short durations and this is something that our batteries do very well.”

An advanced  HP Compaq Business Notebook nw8200 Battery  analyzer evaluates the condition of a battery and implements the appropriate service to restore the battery’s performance. On nickel-based systems, a recondition cycle is applied automatically if a user-selected capacity level cannot be reached.

General Motors Corp. (NYSE: GM), the world’s largest automaker, has been the annual global industry sales leader for 77 years. Founded in 1908, GM today employs about 252,000 people around the world. With global headquarters in Detroit, GM manufactures its cars and trucks in 34 countries. In 2007, nearly 9.37 million GM cars and trucks were sold globally under the following brands: Buick, Cadillac, Chevrolet, GMC, GM Daewoo, Holden, HUMMER, Opel, Pontiac, Saab, Saturn, Vauxhall and Wuling. GM’s OnStar subsidiary is the industry leader in vehicle safety, security and information services.

 Another application involving uneven load demand is the so-called 5?5?90 program used to simulate the runtime of analog two-way radios. The battery is loaded 5 percent of the time on transmit, 5 percent on receive and 90 percent on standby. Other combinations are 10-10-80. Each stage can be programmed to the appropriate discharge current. Because of the complex load conditions, calculating the predicted runtime in the absence of a battery analyzer would be difficult.

 General Motors reserved its second press conference today for battery news. As has been rumored for months, South Korea’s LG Chem has been selected to supply the lithium-ion cells that will power the Chevy Volt. However, LG Chem and its U.S. subsidiary will not be supplying full packs to GM. Instead, GM has decided to keep the pack production in-house along with the battery management systems and all the power electronics. The automaker will be building a pack assembly facility here in Michigan, with LG Chem only supplying the cells.

Battery-specific adapters are available for all major batteries; user-programmable cables with alligator clips accommodate batteries for which no adapter is on hand. Batteries with shorted, mismatched or soft cells are identified in minutes and their deficiencies are displayed on the LCD panel.

In June 2008, the GM Board of Directors approved the Chevrolet Volt program and Voltec? propulsion system for production starting in late 2010. For trips of up to 40 miles, the Volt is powered by electricity from the grid and stored in its lithium-ion  HP Compaq Business Notebook nc8230 Battery  pack. Beyond 40 miles, a small engine-generator creates additional electricity to extend the range of the Volt several hundred additional miles. The development of the Volt’s 16 kWh T-shaped lithium-ion battery, which is roughly 6 feet long (1.8 meters) and weighs nearly 400 pounds (181 kg), is key to the Volt’s success. The production-intent design was revealed in September 2008.

When a vehicle goes into the “auto stop” mode, the engine shuts down, but all accessories stay running. As in some GM hybrids (the Saturn Vue and Chevrolet Malibu, for example), a helper electric motor can also add torque to the internal combustion engine. NiZn batteries will supply the power for these applications. Squiller wouldn’t comment on which automotive manufactures might first use PowerGenix NiZn technology, but the CEO hinted that it would be a company known for its “aggressive” pursuit of environmental technologies. Our bet is Honda and/or Mercedes.

Opening the largest automotive battery lab in the United States (31,000 square feet / 3,251 square meters) that will be capable of testing new energy storage system technologies, as well as lithium-ion and nickel-metal hydride  Dell Latitude D810 Battery, to accelerate the domestic development of advanced battery technology and lead GM’s network of existing labs in Honeoye Falls, N.Y.; Warren, Mich.; Torrance, Calif.; and Mainz-Kastel, Germany. This new Laptop Batteries  lab will be located in Michigan, subject to final negotiations with state and local authorities

Currently, HEVs use Nickel Metal Hydride batteries. The new NiZn formulation packs 30-percent more power into a package that weighs 30-percent less than NiMH power cells. On top of this, the PowerGenix cells cost 20-percent less. The company has retrofitted a Toyota Prius with their batteries, and report solid results from the lighter vehicle.

The Volt’s lithium-ion battery cells will be supplied by LG Chem. Compact Power Inc., a subsidiary of LG Chem based in Troy, Mich., will build battery packs for Volt prototype vehicles until GM’s battery facility is operational. A joint engineering contract with Compact Power and LG Chem also has been signed to further expedite the development of the Volt’s lithium-ion battery technology.

A second important step is keeping the contacts to the battery clean. An eraser is an ideal accessory for any charging station because it’s one of the simplest ways to remove the thin layer of oxide that can build up on the two metal tabs of the HP Compaq Business Notebook NC8200 Battery. Make sure to clean the contacts on the device as well and then blow away any eraser bits.

The word ‘memory’ was originally derived from ‘cyclic memory’, meaning that a NiCd battery can remember how much discharge was required on previous discharges. Improvements in battery technology have virtually eliminated this phenomenon. Tests performed at a Black & Decker lab, for example, showed that the effects of cyclic memory on the modern NiCd were so small that they could only be detected with sensitive instruments. After the same  IBM ThinkPad T60P Battery  was discharged for different lengths of time, the cyclic memory phenomenon could no longer be noticed.

While most people have neither his tools nor his skills, everyone can relate to Mr. Orlov’s frustration when it comes to Laptop Batteries life. It sometimes feels as if an advanced degree is necessary just to keep our phones, P.D.A.’s and laptops running for more than a few minutes. Fortunately, there are some simple principles that solve many of the most common problems — and none of them requires a master’s or a Ph.D.

Getting the Most from your HP Compaq Business Notebook nc8230 Battery
A common difficulty with portable equipment is the gradual decline in battery performance after the first year of service. Although fully charged, the IBM ThinkPad X41 Battery eventually regresses to a point where the available energy is less than half of its original capacity, resulting in unexpected downtime.
Downtime almost always occurs at critical moments. This is especially true in the public safety sector where portable equipment runs as part of a fleet operation and the battery is charged in a pool setting, often with minimal care and attention. Under normal conditions, the battery will hold enough power to last the day. During heavy activities and longer than expected duties, a marginal battery cannot provide the extra power needed and the equipment fails.

The charger they use to refresh the batteries for the two-handed robot.
“They eat batteries really fast because they have three motors,” said Mr. Orlov, a Silicon Valley-based hardware engineer.

Some analyzers are capable of setting the appropriate battery parameters automatically when a battery is inserted. An intelligent battery adapter reads a passive code that is imbedded in most batteries. The code may consist of a jumper, resistor or specified thermistor value. Some battery packs contain a memory chip that holds a digital code. On recognition of the battery, the adapter assigns the correct service parameters. Automatic battery identification minimizes training and allows battery service by untrained staff.

These plug-in hybrids “will cut gasoline demand over 70 percent for most drivers, and carbon emissions by 50 percent, which will have a significant effect on the environment,” Mr. Vieau said. Driving a plug-in hybrid powered by    HP Compaq BUSINESS NOTEBOOK NC4010 Battery  from A123, most drivers would seldom use their gasoline engines. And while the electricity that charged the batteries would derive mostly from carbon dioxide-producing power plants, burning gasoline is the most polluting transportation energy of all, according to a 2005 study by the Argonne National Laboratory.

“In the 1990s, there was a   IBM ThinkPad R60 Battery problem,” he said, but now the lithium-ion cells have been good at delivering the power devices need to accomplish all that consumers expect. With the air of a banker discussing the business cycle, Mr. Buchman holds no illusions: “There will be a  Laptop Batteries  problem again,” he said, “with the cellphones and all of the things people want to do.”

Incidentally, Mr. Wozniak says that new and better circuits are now appearing that measure the   HP Compaq Business Notebook NC6100 Battery’s charge directly, avoiding cumulative accounting. “By this time next year we won’t be manufacturing batteries that have faulty fuel gauges on them,” he predicted.

Shifting to the new technology seems to have been a wise, if hard, decision. Today, A123Systems, a privately held venture, has raised more than $102 million in funding from a variety of investors including Sequoia Capital, Motorola and General Electric. It has 250 employees in China, Taiwan, South Korea and the United States. Apart from its developmental work with G.M., it manufactures the   IBM ThinkPad Z61t Battery   that drive Black & Decker and DeWalt professional power tools.

But self-assembling batteries, despite their intriguing potential, proved intractably hard to develop — or, at least, more expensive and less sure than the immediate commercial possibilities of a rechargeable lithium battery with novel applications. “It just wasn’t working,” said Bart Riley, another of the co-founders, and A123’s vice president for research and development. (The third co-founder is Ric Fulop, now vice president for business development, who has also participated in the start-up of five other companies.)
Rechargeable lithium batteries have been used in laptop computers and mobile phones since the early 1990s. (Their common name, “lithium ion batteries,” is a tautology, since all batteries conduct electric current by allowing the passage of ions between two electrodes.) But despite their lightness, rechargeable lithium batteries — which often use a compound of highly reactive cobalt oxide — have hitherto been thought impractical for transportation because they are insufficiently powerful and might, if pierced, jarred or overheated, explode or burst into flames.
Opinions vary on the best way to avoid frequent recharging. The advice depends heavily on the type of battery. Mr. Wozniak, for instance, suggests disconnecting your battery if you use your laptop as a desktop replacement. The heat and the constant charging wear it down.

The new Dell batteries, which the company hopes to distribute over the next four weeks, will be made by Sony and other vendors. Dell said it was confident that Sony had solved the problem by changing part of its manufacturing methods.

In negotiating deals, “we try to sit down with clients and understand their goals long-term,” Mr. Bund said, before assembling packages composed of the various properties under the Disney/ABC Unlimited banner.

“We say these are like snowflakes,” he added, “no two alike.”

 Rather, Dell said the cause of the fire was a short circuit in one of the fuel cells. It was caused by microscopic metal particles that contaminated the electrolyte. Dell thinks that the particles were released when the case of the cell was crimped near the end of Sony’s manufacturing process. It was the same problem associated with the 22,000 notebooks that Dell recalled in December.

 Disney/ABC Unlimited has recently made deals with marketers that in addition to Spectrum include Kao Brands, for John Frieda hair care products; Sears Holdings, for Sears, Roebuck; and the TJX Companies, for the Marshalls discount-store chain.

The deal also makes sense from a perspective of consumer demographics, Mr. Lumley said, because, he estimated, “65 to 70 percent of   HP Compaq Business Notebook nc2400 Battery   sales are to moms.”
The unit worked when it was plugged in to the power cord, despite the fire, which told the investigators that the problem was not with any circuitry or microchips. An X-ray of the battery pack told them the fire was not caused by an overcharged   Acer Ferrari 1000 Battery , because a safety device was still intact.

Dell officials refused to say how many computers had been returned because of heat or fire damage, but said the company had acted on the problem as soon as it realized there might be a pattern. Mr. Gruzen said the publicity surrounding the notebook fire at the Osaka hotel did not prompt Dell to look into the problem, because the company was already having conversations with Sony.

 The Disney-Spectrum agreement is indicative of how marketers are rethinking their media decision-making. They are viewing purchases more broadly than just buying one network, magazine or Web site at a time.

The portable  Laptop Batteries  industry has said there is not a broad problem with lithium-ion battery fires. But makers have known of the ability of lithium-ion  HP Compaq BUSINESS NOTEBOOK NC4000   Battery  to catch fire since its first commercial use in 1991. In 1995, a Sony lithium-ion battery factory in Koriyama, Japan, was partly destroyed when a   Acer Aspire One AOD150 Battery   undergoing a quality test caught fire.
