Scientists at Stanford University. say they have developed an aluminium battery that can charge a smartphone in as little as a minute. "The battery, which is so flexible it can be folded, could replace alkaline and lithium-ion batteries that are used by millions of people every day according to the Stanford University researchers who developed the new device". Wired magazine reports that the battery can be charged and recharged thousands of times, and is better for the environment than current widely-used batteries because of its durability. If you can charge your Smartphone battery in 1 minute with a life of 7500 cycles, would you care if the battery was not removable? Hop over to WIRED for more info.
