NOVELTY - Surface of current collector, the current collector of the utility model claims a vertically-oriented surface modification to modify a layer of vertical alignment of the graphene nano sheet. The current collector is a condition for a carbon source gas, no amorphous carbon etching gas, the mixed gas composed of argon gas as precursor, using plasma-enhanced chemical vapour deposition method, and it needs no binder is low. This utility model collector surface modification layer is composed of a vertically oriented graphene nano-piece of network structure, a dense graphite exposed edge, current collector and active material to fully contact, reduces the internal resistance, which is capable of realizing high power density and high energy storage is super capacitor and secondary battery and other energy-storage devices.
