Energizer promises new and improved zinc-air battery for summer 2010
Energizer has been working on zinc-air batteries for quite some time now (along with plenty of others), but it looks like its now finally set to deliver with a new "standard battery" that's said to be on track for a launch sometime in the summer of next year. What's more, while some of the company's previous attempts at zinc-air batteries have only been able to manage average run times of between one and three months, Energizer says it's recently been able to triple things in time for the batteries' big debut. That will first come in the form of some AAAA batteries from Energizer itself, which will apparently be priced similarly to "special lithium batteries," and will eventually be followed by zinc-air batteries in a range of different sizes. During the same time, we should also start to see some of the first products with integrated zinc-air batteries from some of the 30 odd OEMs now working with Energizer, who are working to put the batteries into everything from Bluetooth headsets to remote controls to portable audio players.
Rechargeable zinc-air batteries promise a lot, we'll see if they deliver in 2010
Is there any other field of technology that promises as many revolutionary innovations as battery makers do yet delivers so few? We've heard of battery life being made four times, eight times, even twelve times better... and seen pretty much none of it pan out in any sort of meaningful way. Zinc-air batteries are also nothing new, but now some whizkids up in Norway have figured out how to make them rechargeable and set up an entire company, ReVolt, for their commercialization. With more than double the energy density of regular Lithium-Ion batteries, safer operation, lower cost of production, and environmentally friendlier ingredients, ReVolt's tech sounds as sweet as anything, but we'd advise waiting for the pudding-based proof before getting excited. Plans are for small hearing aid and cellphone batteries to show up in 2010, and if all goes well there, larger cells for electric vehicles could also follow. Sure. [Via PhysOrg]
KFE's new phone charger powered by zinc-air batteries, science
Those AA alkaline- and lithium-powered phone chargers are a totally handy (and relatively inexpensive) thing to throw into a bag and carry around in the event -- the incredibly likely event -- that you end up running your set dry at one time or another, but there's a small problem: those AAs don't go very far. Generally speaking, you'll get a couple charges out of a set of batteries, which makes them environmentally dubious at best and less convenient than you'd like them to be. That's where KFE Japan's new solution comes in: same concept, but the batteries are zinc-air instead of alkaline or lithium -- the same tried and true chemistry used by hearing aid batteries -- whereby you pop a lid open on the charger to expose the batteries to air, which starts the juice flowing. The advantage is that you're looking at about 20 charges before the thing's depleted, and when you're there, you'll be able to send it back into KFE to be recharged. The chargers will run 3,000 yen (about $31) when they launch in March. [Warning: subscription required]
Energizer introduces thin, powerful Zinc Air Prismatic battery
Energizer hasn't exactly been keeping this one much of a secret, but the battery maker has now finally gotten official with its much-vaunted Zinc Air Prismatic battery technology, which it says will allow electronics manufacturers to make devices that last longer and are smaller and lighters. The batteries themselves make use of the same zinc air technology used in hearing aid batteries, and apparently have the highest energy density of any portable consumer power solution, which translates to about three times the runtime of a similarly sized alkaline or lithium ion battery. What's more, Energizer says that the zinc air batteries offer a "much lower cost" for OEMs compared to lithium ion batteries, which comes at least in part from the elimination of the need for charge circuitry and a charging device. Of course, the batteries are still quite a ways from finding their way into some actual products, but Energizer will apparently be trying to speed things up a bit by holding design seminars for OEMs throughout 2009.
