US Team Claims Battery Breakthrough

Microsoft Future

30 times smaller and 1000 times faster charge. Those credit card phones might come sooner than we think. A team from the University of Illinois Urbana-Champaign has recently published results on some interesting new tech. In a 3D format, researchers were able to create micro-batteries that decrease the flow distance for electrons and ions. The result, a faster charge time in a smaller form factor.

The process has already proven to be repeatable and attempts are underway to make it viable for small electronics. A big hurdle still remains however, and that is safety. You can’t simply jam that much power into a small size without having some stability issues.

Regardless, if perfected, we could soon see smartphones have the same battery life as E-ink type e-readers… and I can finally get playtime on my 3DS that lasts longer than 4 hours.
