Fraunhofer takes a stab at non-exploding lithium-ion batteries
It's hardly the only one working on making lithium-ion batteries a little less likely to blow up in your face, but the prolific folks at Fraunhofer Institute seem to think that they've come up with a solid contender for your future laptop or cellphone, and they're now set to take the wraps off it at the Hannover Messe conference later this month. The key to their solution, it seems, is the use of a non-flammable polymer electrolyte instead of the liquid electrolyte now commonly used in lithium-ion batteries. While that switch cuts down on the explosiveness, it also introduced a fair number of challenges, not the least of which is the fact that polymer becomes less conductive as it gets more solid. Fraunhofer's apparently made some significant progress on that front, however, and while they're still not completely satisfied with the conductivity, they say the batteries could be ready for commercial use in three to five years. They also, not surprisingly, see no end to the uses for 'em, saying that they could not only wind up in laptops and cellphones, but power tools, lawnmowers, and potentially even cars.[Thanks, Mademoiselle Y]
Researchers improve Li-on battery life, increase capacity 30 percent
Although's Moore's Law continues to race along, battery tech hasn't nearly kept up pace -- so we're excited by developments like the one just announced by Argonne National Labs, which has managed to increase Li-on capacity by 30 percent while making the batteries safer and longer-lasting. The secret ingredients in Argonne's new juice box are a new composite battery material that's partially electrically inactive and manganese oxide-based electrodes in place of the traditional cobalt oxide. Argonne says it's already licensed the tech to Japanese manufacturer Toda Kogyo, which has the capability to produce 30 million laptop batteries a year, but the lab is still working on improving charging rates -- while it's adequate for laptops and cellphones, the battery will need to discharge at least three times faster to work in a car. No word on when we might see these start shipping, but you can bet "manganese battery" is being added to our dream machine spec list right... now.[Via ExtremeTech]
Japan orders Apple to investigate exploding iPod nanos
Uh oh. Japan's trade and economy ministry is now officially investigating the explosive nature of the iPod nano. The culprit is model MA099J/A -- AKA, the old black and white plastic model already reported to spew "chest high flames," cause bedroom fires, and explode across the floor. The Japan incident occurred in January when an iPod nano reportedly "shot out sparks while recharging." At this point, all odds are with the nano's lithium ion battery. Apple Japan has been ordered to investigate the issue and report back to the ministry with the cause. Kind of like asking the fox what it was doing in the hen house, eh?Update: Apparently, the Japanese ministry "strongly warned" Apple for failing to report the incident (as required by law) when it occurred. Apple's filing with the ministry came on March 7th.
Toyota already looking beyond lithium-ion batteries
If you can believe it (and we think you can), Toyota is already hard at work on a new battery system to replace its lithium-ion units currently slated for use in upcoming models. According to a report in Automotive News Europe, the company is hoping to adopt a more advanced battery for its hybrid vehicles in about 12 years as part of its Global Vision 2020 plan. The automaker won't say what technology it plans on moving towards, though it has suggested that air-zinc batteries could be a possible solution for maintaining its dominance in the hybrid vehicle market. In June the company will launch a new division dedicated to developing technologies for future cell power, while its lithium-ion vehicles will hit the roads around 2010.[Via Autoblog]
Toshiba's Super Charge Li-ion batteries: will crush, won't explode
Surely you remember the fear and lawsuits resulting from the 06/07 Lithium-battery fiasco? Who could forget. That's why Toshiba's going out of its way to assure us that their new "Super Li-ion" batteries (SCiBs) revealed yesterday will not result in an equally super meltdown. The new SCiBs feature a high flash point and separator with high heat resistance. As such, they are far less likely to suffer a thermal runaway resulting from a short-circuit. Don't believe us though, check the pneumatic, crush-test from Tosh after the break. We've even thrown in the ol' exploding laptop video for comparison. Ah, those were the days.
iPod "nana" spews chest-high flames from trousers -- lawsuit at 11
Prepare to be amazed at what passes for investigative journalism on television these days. Atlanta's WSB-TV Action News team ran a sensational iPod "nana" piece last night under the title "Man's Pants Catch Fire At Airport." To set the stage, WSB-TV says that the nano "uses the same technology as those troubled laptop batteries under recall due to the risk of fire." In steps Danny Williams -- mild mannered consumer, airport employee -- who claims that his iPod nano "burst into" chest-high flames while he was at work. So why isn't he covered in burns after exposure to such a serious chemical fire? We've all watched the horrifying video of a lithium ion battery explosion, right? Well, Danny claims that he was protected by a "glossy piece of paper" in his pocket at the time. Taking it up a notch, WSB-TV worries that Danny could have been mistaken for a terrorist due to his smoking airport trousers. Look, we're not saying that nothing happened, after all, we've written about an exploding iPod nano before. We're only saying that it didn't happen in the way described. Check the video of the hot-coffee-in-lap style legal preparation after the break. [Thanks, Will]
Toyota delays next-gen Prius while GM inks deal with lithium-ion maker
It looks like those waiting for the next generation Prius to hit the road are going to have to hold out a little bit longer. Toyota announced this week that it would be delaying plans to bring its plug-in, lithium-ion-based model to market until 2011, as opposed to 2008, due to safety concerns over the company's chosen battery. In very related news, GM has struck a deal with Massachusetts-based battery developer A123 Systems to produce flat lithium-ion batteries for use in upcoming plug-in electric vehicles, such as the Chevy Volt. With regards to whether Toyota's setback could give GM an edge in the electric car game, Vice Chairman Bob Lutz said, "I think that our No. 1 competitor has some problems with their technology, and I do think that it very definitely opens a window of opportunity for us to be first to market with a genuine plug-in hybrid," which sounds like fightin' words, if you ask us.Read -- Toyota delays next-gen lithium-ion PriusRead -- GM says it could lead electric car race
Lithium Ion motorbike prototype is emission and sound-free
Now that Tesla Motors has resurrected the electric car in screeching sports car form, it's the turn of the motorbike to get all Lithium Ioned up. While it's not the first electric motorcycle, it is possibly the most rough and ready design: if you can afford the $15,000 odd fee for a custom modification, a team at the Electric Motorsport shop in Oakland will take out the nasty engine in your ride and replace it with an array of Lithium Ion batteries. As a prototype, the company created a fully electric version of the Yamaha R1 which has a top speed of 100MPH, a range of 100 miles, does 0-60 in 3 seconds, and looks pretty damn ugly to tell the truth. Ya' see, the number of brick sized Lithium Ion batteries required to eke out this level of performance is 28, which have to fit all willy nilly underneath the bike. Fortunately, the company hopes to produce a more refined production model, as well as a cheaper design with less advanced performance.[Via Digg]
Wii-chargeable battery packs (almost) ready for release
"Where are the Wii-chargeable battery packs?" we asked last week. This week, we have the answer: "There they are!" That is, they can be reserved in Japan as of today, for eventual delivery before the end of February, and we have Japanese gizmo manufacturer Thanko to thank-o. Thanko's lithium-ion battery and USB charge cradle, which can draw power from one of the Wii's USB ports, are retailing in Japan at ¥3,480 (US$29) per set or at the slightly discounted rate of ¥6,480 (US$54) for two sets. A three-and-a-half hour charge will, according to Thanko's press release, keep a Wii Remote powered for 25 hours. Just think how many times you could complete Kororinpa in that time...
Matsushita to begin production of new, non-explosive Li-ion batteries
Apparently Matsushita isn't waiting around for the (notoriously slow) IEEE task force to settle on a new Li-ion battery standard, as the company has announced that it will soon begin "mass production of a new lithium-ion battery that is safe from the overheating problems" we're all too familiar with. These batteries in particular will be built to replace those that prompted a massive recall of Sony cells earlier this year, and should be available en masse "by the end of the year." Sony's global recall affected "around 9.6 million cells" used on nearly every laptop under the sun, so we're sure Matsushita's conveyor belts will be approaching record speeds to crank out these replacements. Notably, the company asserted that while actual pricing would depend on the quantity ordered, it would be "higher than existing models" regardless -- which makes sense considering all the loot Sony is losing from this fiasco.[Via Laptoping, thanks Kaztm]
Boston-Power promises better, safer lithium-ion batteries
Startup tech company Boston-Power seems to think it has a solution to the many woes plaguing lithium-ion batteries, emerging from stealth mode today (otherwise known as issuing a press release) to announce that it's raised more than $8 million in Series A financing. Not surprisingly, they're keeping most of the details on the batteries themselves under wraps, saying only that they employ "novel chemistry with groundbreaking innovations" to provide longer life, faster charging and -- most importantly to laptop manufacturers potentially looking to buy 'em by the truckload -- greater safety. The first cells using the company's seemingly cure-all technology are set to be available in the first half of next year, although we're guessing that we'll have to wait a little while longer than that for public consumption.[Via EE Times]
Zinc Matrix Power unveils silver-zinc battery to trump li-ion
We've been overdue for a lithium-ion successor since forever, and we can't deny the urgency has been bumped a notch by the recent spat of battery explosions. Of course, many have pretended to the throne, but newcomer Zinc Matrix Power thinks their new silver-zinc battery packs really have a shot. They just unveiled the tech at the Intel Developers Forum, and they claim their batteries are safer, longer lasting and more environmentally friendly than those lithium-ion clunkers. As much as we treasure our lap in an intact form -- which silver-zinc provides for due to a safer "inherent chemistry" of silver, zinc and water -- we're especially happy to hear of the "significant" performance gains over lithium-ion, because if there's anything we hate worse than shrapnel in the upper thigh, it's running out of battery mid-way through a high-scoring game of Snood on a cross-country flight. We suppose easy recycling wouldn't suck either. Zinc Matrix says they'll have the new power cells in the hands of device manufacturers for evaluation in early '07, so hopefully we won't have too long of a wait.[Via Tech Digest]
Are lithium-ion cars the next great source of violent camphone pics?
It's hard to imagine a world where a few batteries strapped together is more dangerous than an internal combustion engine, but with the recent publicity exploding laptop batteries have been getting, lithium-ion-based electric cars aren't looking so much like the "safe alternative" anymore. According to U.S. Consumer Products Safety Commission, more than 300 cell phone and laptops batteries overheated or caught fire from 2003 to 2005, with plenty of personal injury thrown into the mix. Car battery packs just compound the problem. That new Tesla roadster, for instance, packs in nearly 7,000 batteries behind the passenger compartment. Tesla's CEO says they've done much more than the average consumer electronics manufacturer to keep their system safe, including liquid cooling, overcharge protection, three layers of fuses, and sensors to automatically disconnect the batteries in case of high-temperatures or if the car rashes. The individual batteries are also each protected in their own steel case to isolate them from the other ticking time-bombs power units. Unfortunately, even with the best engineered safety precautions, an accidentally faulty manufacture is out of the designer's hands, and if one batter explodes violently enough to effect neighboring cells and start a chain reaction. Even with a failure rate of one in ten million, the odds are still pretty high for failure with 7,000 batteries in every car. As per usual, we will attempt to avoid reality, glue our cellphone to our skull, keep our MacBook in our lap, and drag race our Tesla roadster like there's no tomorrow. 'Cause just like Alphaville said -- do you really want to live forever?
Valence's less-explosive lithium-ion batteries
With laptops blowing up left and right, it's no surprise that the same lithium-ion battery technology has been slow to take off in larger applications, like cars, where the danger of spontaneous combustion is even more serious. But as CNET reports, at least one company says they've managed to create a lithium-ion car battery that's safe enough to power your ride. Valence Technology's U-Charge Power System keeps the fireworks in check by using a metal phosphate cathode instead of the cobalt oxide cathode commonly used in lithium-ion batteries. The downside to that choice is that the battery can only store about 75% of the power of traditional batteries, but then again, it won't catch on fire. While the batteries have so far only been put to use in wheelchairs, scooters and hybrid vehicles, the company says that the technology could eventually be adapted for use in laptops -- though we're sure not everyone's gonna be willing to take a performance hit just for a bit more peace of mind.
NTSB looks to laptop batteries as possible cause of plane fire
It looks like laptop batteries are fast gaining on cellphones as the technology most likely to kill you, or at least give you a nasty, potentially embarrassing burn. Hot on the heels of Dell investigating its own case of spontaneous combustion, the National Transportation Safety Board (NTSB) is now getting in on the act, looking into the possibility that laptop batteries may have started a fire on a UPS cargo plane that was forced to make an emergency landing last February. The plane's three crew members managed to escape with only minor injuries, but the fire ultimately destroyed the plane and most of the cargo on board. While the NTSB investigation hasn't pinned the blame on the batteries just yet, the FAA's has Harry Webster has testified that lithium-ion batteries can vent flammable liquid and "pose a risk to the cargo compartment." We've already seen warnings not to use your laptop on your lap -- think warnings not to travel with them are far behind?
Better batteries through nanotechnology
We've seen hybrid batteries, hairy capacitors, and ultracapacitors, but considering how much we depend on batteries, we're not ones to turn up our noses at yet another new battery development. This latest one comes from researchers in France, who have turned to nanotechnology to create lithium-ion battery electrodes that have several times the energy capacity of traditional electrodes, meaning that batteries could either be significantly smaller or remain the same size and squeeze a whole lot more juice out of a single charge. Of course, one of the many big application for nano batteries is in remote sensors and medical implants, where smaller and longer lasting are definitely better. Which is probably why those smaller-scaled applications are the first we're likely to see, as larger electrodes are currently far less efficient than small ones. Thankfully the researchers at hand believe the technology could eventually be used to power electric and hybrid vehicles, which is always the dream, right?[Via MobileMag]
