Stanford's aluminum battery fully charges in only one minute

Lithium-ion batteries are actually a boon to the modern world -- they've replaced the heavier, single-use alkaline type in many methods from wristwatches to jumbo jets. Unfortunately, these rechargeable cells happen to be struggling to keep with flow our ever-increasing energy needs. But a brand new style of aluminum-ion battery developed at Stanford University isn't solely less explode-y than lithium, but can also be built for a fraction of the value and recharges completely in just over a second. Best off, " Our new battery won't catch fire, even though you drill through it, " Stanford chemistry professor Dai Hongjie boasted inside a recent release.

Unlike earlier aluminum batteries, which generally failed after only about 100 recharge cycles, Stanford's prototype can cycle a lot greater than 7, 500 times with virtually no capacity loss -- 7. 5 times longer than your average li-ion. The aluminum-ion cell is not perfect (yet) because it are only able to produce about 2 volts, far lower than the 3. 6V that lithium-ion an muster. Plus aluminum cells only carry 40 watts of electricity per kilogram when compared with lithium's 100 to 206 W/kg power density. " Improving the cathode material could eventually boost the voltage and energy density, " said Dai. " Otherwise, our battery has everything else you'd dream a battery should have : inexpensive electrodes, good safety, high-speed charging, flexibility and long cycle life. I see this as a brand new battery in its early days. It is quite exciting.
