    On Wednesday night, Stanford Ovshinsky, inventor of the nickel-metal hydride (NiMH) battery, passed away at the age of 89 due to complications from cancer. The Akron, Ohio native may not be a household name, but there's a good chance that many of your electronics have been powered by his work, as NiMH batteries are used in everything from mice to hybrid cars. A self-taught inventor who didn't attend college, Ovshinsky held hundreds of patents, received a number of honorary degrees and is even the namesake of a branch of electronics dubbed Ovonics. Flat-panel displays, solar cells and even phase change memory are just a handful of other technologies that his work helped to develop. Next time you pick up a modern gadget, just remember that Ovshinsky is partly responsible for its existence. [Image credit: Joi Ito, Flickr]

    Quick: What costs hundreds of dollars and dies after four hours? If your answer included anything portable and tech-based -- you guessed right. In fact, most of our magical and exciting gadgetry has less-than-stellar means of holding a charge, but a recent breakthrough by Sumitomo Electric Industries could change all that. Employing the same process used to create Celmet (a NiMH component), researchers at the R&D company managed to coax aluminum into being a bit more receptive. The resulting Aluminum-Celmet has a whopping 98 percent porosity rate, leaving the Li-ion gate wide-open for a flood of electrical juice. And unlike its nickel-based brother, this piece de porous non-resistance has a steep corrosive threshold that could soon help power a line of high-capacity, small form rechargeable batteries. Production is already underway at Osaka Works, with SEI hoping to speed adoption of these franken-batts into our mass consuming mitts. Technical-jargony PR release after the break.

    If you love Sanyo's ever-so-practical Eneloop rechargeable batteries, you'll be smitten with its two latest AA additions. First into the battery compartment is the 2400mAh Eneloop Pro; it's loaded with twenty-five percent more juice than the standard model, and is a perfect match for your power-draining Nikon Speedlight -- not quite as formidable as the 2,500mAh XX series, though. Moving onto the next slot is the Eneloop Plus, which adds a positive temperature coefficient thermistor -- a resistor that prevents the batts from reaching skin-scorching heat levels in kids' toys. Blazing Hello Kitty anyone? Both will come in packs of two or four, and also as bundles with a charger. Residents of Japan will be able to pick up the batteries at varying points this year, but aside from the ¥1,260 (about $15) Pro two-pack, pricing remains open.

  • Styrofoam touches electrodes to create incredibly fast-charging wonderbatteries

    Elon Musk's heart may have already given up on the humble battery, lusting after capacitors, but researchers at the University of Illinois have think there's life in the 'ol cells yet, creating batteries that charge and discharge in seconds. They've found a way to create electrodes using polystyrene beads as a sort of substrate, tiny spheres helping to set the porosity of either the nickel-metal hydride or lithium-manganese capacitor material. By adjusting the size and density of the bean bag innards the team was able to create an electrode porosity of 94 percent, which is just a few ticks short of theoretically ideal for exposing the maximum surface area of the electrode to the battery material. This results in extremely fast charges and discharges, the NiMH cell hitting 90 percent capacity in just 20 seconds and discharging in as quickly as 2.7 seconds. While we don't know just what kind of charging system the team was using to achieve this, even assuming a high-amperage stream of electrons this is still a remarkable feat. But, like most major advances there's a drawback: similar to Toshiba's SCiB batts the capacity of these cells is only about three quarters what it would be using normal battery construction, meaning you'd need roughly 25 percent more mass to get the same range in your ultra-fast charging EV of the future. That might just be a worthy trade-off.

To mark this occasion, the Swiss company sent us a review unit for some sweet wireless charging action. Read on for our full review after the break.%Gallery-107485%

  • Apple's rechargeable AA batteries are rebranded Sanyo Eneloops?

    You do realize that Apple doesn't manufacture its own batteries, right? Apple, like most consumer electronics companies, doesn't actually make anything. So where do Apple's new AA rechargeable NiMH batteries comes from then? We had a suspicion early on that Apple's "new" AAs were actually Eneloops, long one of our favorite brands of modern rechargeables due to their ability to maintain a 75% charge even after three years inside the kitchen utility drawer. Now our Czech friends over at Superapple seem to have confirmed this after an exhaustive teardown and analysis of Apple's little power cells. Specifically, Apple's AA batteries appear to be none other than the 1.2V Sanyo Eneloop HR-3UTG rated at 1,900mAh (minimum). While Superapple couldn't find any physical evidence linking the two, the measured performance characteristics of Apple's AA batteries matched the Eneloops perfectly. Knowing this, are you really going to spend $29 for the Apple charger and 6x AA batteries when you get 8x AA Eneloops and charger for the same price? Now mosey on past the break if you want to see a AA unrolled. Fascinating stuff. [Thanks, Roman K.]

    Toyota continues to lead the silent race to efficient cars with plans to introduce a plug-in hybrid in 2010 that will use lithium-ion batteries. Meanwhile, Toyota has been working with Matsushita Electric Industrial Co to develop batteries that will outperform lithium-ion batteries for its plans to introduce hybrid versions of every single car in its lineup between 2020 and 2029. If that seems too far away, the next generation Prius, due next year, will use NiMH batteries. Toyota president Katsuaki Watanabe told reporters in Tokyo that it's time to move past oil and get serious about electric power. "Our view is that oil production will peak in the near future. We need to develop power train(s) for alternative energy sources."

    It's about time 360 owners get some rechargeable Nyko love via the Charge Base 360, which is shipping to stores at a $34.99 clip. So why should you care? This charger / controller storage solution comes with two NiMH drop-in (i.e. shaped for your 360 controller) rechargeable batteries that promise to make your gaming downtime a lot less extant. Nyko says a single charge will provide "up to" 25 hours of play time while charge time takes about 2 hours per controller. If you act quickly, you could get one of the limited 80s coffee table-friendly Black & Gold-colored units which go on sale June 2.[Via IGN]

  • Kawasaki Heavy Industries to unveil NiMH-powered SWIMO

    It's no secret that the engineering minds of the world are developing new ways to get you (and all your co-workers) around without making a pit stop at the fuel station. Joining the growing list of battery-powered cars, supercars, and even scooters, the SWIMO streetcar is set to make mass transit a greener endeavor. Kawasaki Heavy Industries (KHI) is making the wires most typically associated with trolley cars a non-issue with its "giga cell-powered" SWIMO. Rather than relying on fancy fuel cells, the juice is delivered from those tried and true nickle metal hydride batteries we've been using for years in less demanding applications. While you won't be going far on a single charge (about 6 miles, maybe a tad more going downhill), recharging stations at various subway stops could keep the wheels turning 'round the clock without a drop of gasoline. Slated to hit the streets of Japan sometime in 2007, the SWIMO transporter should make the daily commute a bit gentler on mother Earth, and we can imagine KHI getting some serious tax credits if these things ever show up on American soil.[Via MobileMag]

  • Air Oxyride: 100 batteries included

    Panasonic has bumped up the power of its Oxyride batteries, claiming the new version is 120% more efficient than the original model. And to prove it, Panny has decided to launch an airplane powered by 100 AA Oxyride batteries (you might recall that the original Oxyride was heralded by a battery-powered ultralight vehicle). No word on how far the plane will be able to go powered on those AAs -- or whether Panny's actually managed to recruit anyone to fly the thing (though we hear Richard Branson is game). We assume that, after this stunt, Panny will roll out next year's upgrade with an Oxyride-powered space shuttle, and follow that one with a battery-powered lunar colony. Maybe after that, they'll consider something really dramatic, like beating disposable lithiums or rechargeable NiMHs in a digicam.
