  • Breathing batteries could store 10 times the energy

    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...

    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...

    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.

    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...

For many consumers, having to routinely recharge or replace batteries remains the weakest link in portable electronics. To solve the problem, a group of European researchers say they've found a way to combine a thin-film organic solar cell with a new type of polymer battery, giving it the capability of recharging itself when exposed to natural or indoor light. It's not only ultraslim, but also flexible enough to integrate with a wide range of low-wattage electronic devices, including flat but bendable objects like a...

    Grazing the Nanograss - Adaptable substance may cool computers and put a zoom lens in your cell phone. Future Watch by Gary H. Anthes OCTOBER 11, 2004 (COMPUTERWORLD) - A drop of water glides across the flat surface like quicksilver, moving effortlessly from place to place as the surface is tilted. It's hard to believe that the little bead is water, for it doesn't wet the surface as it races around, seemingly without friction. The little drop in this impromptu laboratory demonstration isn't on an ordinary surface. It's riding on "nanograss," a bed of upright silicon posts a thousand times...

"Apple is not financially responsible for this recall," Apple spokeswoman Natalie Kerris said. Apple has received four reports of overheating though no injuries have been reported, the consumer protection agency said. The recall affects...

  • Batteries created for deep-space exploration - NASA to send an exploration device to Pluto.

    IDAHO FALLS -- A team of Idaho scientists is working to ensure space exploration takes place in the future. The experts at Argonne National Laboratory-West are developing batteries called radioisotope thermoelectric generators. Their budget for the next 18 months is estimated at $21 million. Department of Energy officials moved the nation's space battery program from Ohio to Idaho last year because of security concerns stemming from the September eleventh terrorist attacks. The plutonium in the batteries produces heat, which can power spacecraft for decades. NASA plans to send an exploration device to Pluto in 2006.
  • Power from blood could lead to 'human batteries'

    08/03/2003 11:10:36 AM PDT · by yonif · 33 replies · 840+ views
    A device that produces electricity from blood could be used to turn people into "human batteries". Researchers in Japan are developing a method of drawing power from blood glucose, mimicking the way the body generates energy from food. Theoretically, it could allow a person to pump out 100 watts - enough to illuminate a light bulb. But that would entail converting all the food eaten by the individual into electricity. In practice, less power would be generated since food is needed by the body. However the scientists say the "bio-nano" generator could be used to run devices embedded in the...

    It's early April, days before the fall of Baghdad, and a convoy of trucks from the 11th Signal Brigade is rolling through southern Iraq. The mission: establish a digital beachhead in central Iraq. Without this advance node and a handful like it, the Army's Third Infantry Division cannot receive the precise targeting information it needs to fight its way into the capital. About 9 am, soldiers in the convoy see something that fills them with dread: four dead sheep by the side of the dusty road. Within a mile, they spot two more and quickly pull the convoy to a...

    Riddle of 'Baghdad's batteries' Arran Frood investigates what could have been the very first batteries and how these important archaeological and technological artefacts are now at risk from the impending war in Iraq. I don't think anyone can say for sure what they were used for, but they may have been batteries because they do work Dr Marjorie Senechal War can destroy more than a people, an army or a leader. Culture, tradition and history also lie in the firing line. Iraq has a rich national heritage. The Garden of Eden and the Tower of Babel are said to have...

    Boy, I hate daylight savings time for a ton of reasons. I hate getting up at 2 am sunday morning to change the batteries in my smoke detector. Oh, yes, if you try to change them early, or late, they detect that. And call the fire department. Since I've saved time all summer long, do you think the government will give me credit for it? Spring ahead, fall back. Now I have to remember a nursery rhyme to tell the time. This is dumb. Well not as dumb as "twinkle , twinkle, little star, now I wonder what time you...
