Researchers from the Korean Sungkyunkwan University announced the development of a sponge-like electrode material using graphene and a polymer that enables the assembly of a light and efficient graphene battery.
The electrode was made from porous graphene aerogel that was a result of combining alcohol and graphene. The graphene aerogel electrode material is easily compressed and highly durable, with about 90-99.9 percent of it filled with air and pores smaller than 100 nanometers that form a 3D web.
The researchers state that they have achieved a battery that is 10 times smaller than existing graphene batteries, but have similar performance capabilities. Moreover, it was able to maintain the same product performance even after going through the compression and restoration process for more than 10 million times.
The Korean researchers claim that their graphene aerogel electrode material is expected to be utilized in the energy storage equipment of electric cars, mobile devices and aerospace equipment, which have been hard to develop using conventional batteries due to limits in volume and weight.

Those energy strage devices are not batteries they are ultracapaciators.
