Stanford team develops asymmetrical supercapacitors based on graphene hybrid materials; high energy and power densities

Green Car Congress

Supercapacitors in aqueous solutions are low-cost energy storage devices with high cycling stability and fast charging and discharging capabilities, but suffer from low energy densities. The resulting supercapacitor showed a high energy density of ~48 Wh/kg at a power density of ~0.23 Wang et al.
