Researchers build aluminum battery that can be charged in one minute

If there's one major issue plaguing smartphones, smartwatches and other gadgets we use every day, it's battery life. Now, a team of researchers at Stanford University has built an aluminum-ion battery prototype which offers several improvements over today's ubiquitous lithium-ion batteries, including super-fast charging times

The team's aluminum-ion battery sounds like a dream come true for gadget manufacturers — a perfect battery with few flaws.

Until now, aluminum-ion batteries weren't able to produce a high enough voltage, especially after many recharge cycles. But the prototype created by the Stanford researchers consists of an aluminum anode and a cathode made of graphite — a combination of materials that allows for producing sufficient voltage (about two volts), even after thousands of recharge cycles Read more...
