Using Holes to Build a Better Battery

Nov-14-14 By building a battery full of tiny nanopores, researchers have created a postage stamp-sized battery that can be fully charged in just minutes.

The battery, based on a tiny structure developed by a team from the University of Maryland, consists of a sheet of ceramic that has been filled with millions of nanopores. These nanopores each contain the electrolyte solution and are fitted with a tiny electrode at either end, which function as the anode and cathode. Since the nanopores are all the same size, they can be packed together very tightly to work together. According to the team, the battery can be fully charged in just minutes, and can be recharged and discharged thousands of times.
