Whether it's your smartphone, your electric car or the backup batteries for a server farm, a new kind of 3D battery electrode is aiming to boost both their output and recharging speed by up to 100 times.

3D structures are adding the third dimension to a whole array of applications today, and now battery electrodes are following suit, increasing their ability to deliver lots of current quickly and speeding up their recharge time.
Batteries have long been the weak link in the forward march of technological progress, mainly because the chemistry of their reactions is fixed by the laws of physics. However, by adding 3D patterning to the battery electrodes where these chemical reactions take place, recharging can be accelerated by as much as 100 times
