SKKU developed tech to make graphene batteries 10x smaller, same strength

2015_02_aerogel batteryA Korean research team has successfully developed a technology to make a sponge-like electrode material using graphene and a polymer, leading to a graphene battery. The newly-developed battery is ten times as small as existing ones, but can show the same product performance.

A research team headed by Park Ho-seok, professor of the School of Chemical Engineering at Sungkyunkwan University (SKKU), announced on Feb. 1 that it has succeeded in developing a very porous graphene aerogel electrode material by combining polyvinyl alcohol and graphene. Studies on developing high-capacity and rapidly-chargeable batteries are underway worldwide. It is necessary to compress devices in order to supply energy in extreme conditions. However, when existing graphene-based batteries are compressed by 30 percent, product performance suffers owing to the destruction of the inside structure.
