Researchers from the University College London designed new graphene-based supercapacitor materials that enable higher power density than current designs. The new materials also enable the production of bendable supercapacitors, without a liquid electrolyte which minimizes explosion risk.

The researchers say the new supercapacitor design can achieve an energy density of 88.1 Wh/L - the highest ever reported for carbon-based supercapacitors. The main innovation is the production of electrodes made from multiple layers of graphene, that enable a dense but porous material.
