METHOD FOR MAKING LITHIUM ION BATTERY

摘要

A method for making lithium ion battery is provided. A cathode material layer and an anode material layer are provided. A first graphene layer is formed on a surface of the cathode material layer to obtain a cathode electrode. A second graphene layer is formed on a surface of the anode material layer to obtain an anode electrode. A separator is applied between the cathode electrode and the anode electrode to form a battery cell. At least one battery cell is then encapsulated in an external encapsulating shell, and an electrolyte solution is injected into the external encapsulating shell.
