摘要：With rapidly development of the economic and society, environmental pollution become a imminent problem in modern society. Super capacitors as a kind of green energy has a broad application prospect, and the graphene is the most commonly used material in super capacitors. This paper mainly studies the impact of different aluminum foil etching conditions on the performance of graphene super capacitor. This paper take the experiments of aluminum foils under different etching time, solution concentration and current density, then analyze the SEM graph, galvanostatic curve and specific capacitance value of different controlled conditions, finally come to the result that at the 3:1 Cl- and SO42- solution concentration ratio, 70mA/cm(2) current density and 140s etching time, the graphene super capacitor has the maximum specific capacitance of 115F/g.
