    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.
