Fullerene-Graphene Based High Efficiency Supercapacitors

This technology provides for enhancing capacitor power density, capacitive retention, and stability by using self growing nano particles on the electrodes of capacitors. Specifically, double-layer capacitance achieve electrostatic storage by separation of charge in a Helmholtz double layer at the interface between the surface of a conductive electrode and electrolyte. The invention couples graphene flakes and porous graphite with self-assembly fullerene to provide the ability to attain high areal and specific electric double layer capacitance.
