Charged in 60 Seconds: Scientists Create Super Battery

Time and time again, you’ve charged your iPhone’s or other gadget’s battery to 100%, only to have it die when you’re nowhere near an outlet.

Those days could soon be over, say scientists at Stanford. According to the team of chemists, they’ve just invented an aluminum-ion battery that could last for longer periods of time, and – the best part of all – fully charge in just one minute.

Unlike the standard lithium-ion battery, which can overheat (even catch fire) and wear out over time, this new prototype has an aluminum anode and a graphite cathode (the negative and positive electrodes, respectively, in a battery). Translation: an inexpensive, flexible, and safe product that can withstand up to 7,500 charges without losing voltage. Compare that to current lithium batteries that usually start to weaken after 1,000 charges, and you’ve got a pretty desirable battery on your hands.

One Stanford chemistry professor said,

“Our battery has everything else you’d dream that a battery should have: inexpensive electrodes, good safety, high-speed charging, flexibility, and long cycle life. I see this as a new battery in its early days. It’s quite exciting.”

The downside? This new aluminum battery still can’t produce the higher voltage necessary for a practical smartphone battery (it currently gives 2 Volts, compared to most lithium batteries that can produce closer to 4V).

And yet, the researches at Stanford remain positive, saying that an aluminum battery with a more competitive voltage won’t be impossible to make.

Say what? A cell phone battery that can charge in just 1 minute and last longer than normal batteries? You gotta have this!
