    The lithium ion batteries used in laptops and cellphones, and tipped for future use in electric cars, are approaching their technological limits. But chemists in the UK say that there's a way to break through the looming energy capacity barrier – let the batteries "breathe" oxygen from the air. A standard lithium ion battery contains a negative electrode of graphite, a positive electrode of lithium cobalt oxide, and a lithium salt-containing electrolyte. Lithium ions shuttle between the two electrodes during charging and discharging, sending electrons around the external circuit to power a gadget in the process. The problem with that...

    The American Thinker Blog ^ | April 08, 2009 | Otis A. Glazebrook IV
    Isaac Martin pointed out in yesterday ’s American Thinker some of the problems with the new technology behind the proposed switch to electric cars -- there are many other issues as well. A few of a multitude of problems are the high cost of the batteries, $25,000.00 for the Tesla’s (6,831 batteries) pack, the pollution problem of replacing and disposing the packs, and the relatively short life span of the batteries. (For example, the life of a lithium ion cell phone battery seems to be about a year and a half. Finding exact information on the actual useful battery life...

    Two researchers have developed battery cells that can charge up in less time than it takes to read the first two sentences of this article. The work could eventually produce ultra-fast power packs for everything from laptop computers to electric vehicles. Byoungwoo Kang and Gerbrand Ceder of the Massachusetts Institute of Technology in Cambridge have found a way to get a common lithium compound to release and take up lithium ions in a matter of seconds. The compound, which is already used in the electrodes of some commercial lithium-ion batteries, might lead to laptop batteries capable of charging themselves in...

    FBI Warns of Potential Terror Attacks The FBI and Department of Homeland Security today issued an analytical "note" to U.S. law-enforcement officials cautioning that al-Qaida terrorists have in the past expressed interest in attacking public buildings using a dozen suicide bombers each carrying 20 kilograms of explosives. Authors with the U.S. Office of Intelligence and Analysis added that they have "no credible or specific information that terrorists are planning operations against public buildings in the United States." The FBI and DHS analysts said they were releasing the note because "it is important for local authorities and building owners and...

    Cnet ^ | August 22nd | Charles Cooper
    Now a start-up called ZPower says it's come up with a battery technology breakthrough which it claims will result in 40 percent longer laptop life than lithium-ion on a single charge. The company says it has struck a deal with "one of the major" PC makers to use its silver-zinc batteries in a notebook line slated for 2009. The CEO, Ross Dueber, declined to get more specific than that. Commercial lithium-ion batteries have been around since 1991, courtesy of Sony and an upgrade would be very welcome.

    <p>One of the Big Ideas that's gotten a boost from the recent oil price shock is the notion that the energy for transportation should come from the electric grid, not an oil well in the Middle East.</p> <p>A number of big, established car makers have announced plans to produce cars that will pull from the electric grid all or part of the energy needed to make them go. They join a flock of upstart companies, such as Tesla Motors, trying to prosper by defining a new generation of mobility technology starting with a blank sheet of paper - or rather a blank video display screen.</p>

    Lithium-ion batteries are both a blessing and a curse when it comes to mobile electronics The topic of exploding lithium-ion batteries has been debated to death in the wake of massive battery recalls over the last couple of years. Amidst the deft public relations maneuvering and finger-pointing, however, the question as to why they explode in the first place is still shrouded in mystery for many. The most important thing to understand here is that lithium-ion technology is considerably more volatile compared to other forms of rechargeable battery technologies. Defects in the insulating membrane can result in a mini-explosion that...

    YOUR WORLD increasingly runs on lithium-ion batteries. Chances are good that your phone, laptop, camera, portable music and video players, radios, and game consoles keep going only as long as there are lithium ions churning around inside them. Lithium-ion batteries are getting into your power tools. Soon they’ll even be in your car. So it’s a shame that after nearly four decades of intensive development, lithium-ion batteries still leave plenty to be desired. They fade fast—although their energy capacity starts out higher than that of any other kind of mass-market battery, it can drop more than 25 ­percent per year...
  • Travelers Advisory: U.S. limits lithium batteries on flights

    TEL AVIV (MarketWatch) - Flying well-equipped for business and pleasure gets a bit more complicated on Jan. 1, as the U.S. Transportation Department bars travelers from packing loose lithium batteries in checked luggage. The move is designed to help minimize the risk that such batteries could overheat and catch fire on board, the agency's Pipeline and Hazardous Materials Safety Administration said in a statement on Friday. The new rules say travelers can bring a laptop computer, digital camera, cellphone and other equipment on board or in checked luggage if their lithium batteries are installed in the items. And flyers can...

    WASHINGTON - To help reduce the risk of fires, air travelers will no longer be able to pack loose lithium batteries in checked luggage beginning Jan. 1, the Transportation Department said Friday. Passengers can still check baggage with lithium batteries if they are installed in electronic devices, such as cameras, cell phones and laptop computers. If packed in plastic bags, batteries may be in carryon baggage. The limit is two batteries per passenger. The ban affects shipments of non-rechargeable lithium batteries, such as those made by Energizer Holdings Inc. and Procter & Gamble Co.'s Duracell brand. "Doing something as simple...

    Stanford Report ^ | December 18, 2007 | DAN STOBER
    Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices. The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers. "It's not a small improvement," Cui said. "It's a revolutionary development." The breakthrough is described in a paper, "High-performance lithium...

    Poultney, VT - Imagine collecting a paycheck from your utility company each month simply for plugging your electric vehicle into the power grid and making it available to supply or download power. "There's a whole new way to look at energy supply and distribution, and our love affair with cars," said Dr. Steven Letendre, professor of management and environmental studies at Green Mountain College. "In the not-so-distant future, electric cars should be viewed both as environmentally-friendly suppliers of services to the power grid and as sources of income for owners."

    WASHINGTON, Sept. 10 — American Electric Power, a coal-burning utility company that is looking for ways to connect more wind power to its grid, plans to announce on Tuesday that it will install huge banks of high-technology batteries. The batteries are costly and their use at such a big scale has not been demonstrated, but they may be an essential complement to renewable power, experts say. “We’re looking at what we believe the grid of the future is going to be,” said Carl L. English, president of A.E.P. “We’re going to need a significant amount of storage if for no...

    HELSINKI, Finland — Nokia Corp. warned Tuesday that up to 46 million batteries used in some of its cell phones could be faulty and pose a risk of overheating. The advisory applies to batteries manufactured by Matsushita from December 2005 to November 2006, the world's largest mobile phone maker said. Matsushita Battery Industrial Co. Ltd. of Japan is one of several suppliers that have together made some 300 million BL-5C batteries. The lithium-ion battery is one of 14 different types of battery used in Nokia phones. Nokia said 100 incidents of overheating of the Matsushita-made BL-5C batteries have been reported...
