▎ 摘　　要

NOVELTY - Negative plate manufacturing involves providing multiple sheets of functional graphene, compressing the functional graphene to faun a graphene target, providing copper foil, and then forming a microstructure on a surface of the copper foil. The graphene target is deposited on the microstructure of the surface of the copper foil to form the graphene layer. The graphene layer is repaired by using an excimer laser. USE - Method for manufacturing negative plate of a secondary battery (claimed). ADVANTAGE - The method manufactures the negative plate in a simple and cost-effective manner with improved electric capacity, energy storage feature, electrochemical activity, and a reversible capacitance of a battery and greatly prolonged cycle life of the whole graphene cathode.
