▎ 摘　　要

NOVELTY - The present invention provides a process method for a graphene electrode and a manufacturing device thereof. The method includes (1): taking a liquid polyimide and infiltrating it into a porous substrate with multiple pores in an ultrasonic spray mode, and thus forming A porous coating substrate; (2): the porous coating substrate moves in a tunnel kiln, and a plurality of carbon dioxide laser irradiators continuously irradiate the porous coating substrate passing through the tunnel kiln with carbon dioxide lasers , The porous graphene substrate is formed into a porous graphene substrate; (3): the porous graphene substrate is subjected to a lithiation procedure, so that the porous graphene substrate forms a lithiated graphene electrode; Therefore, a new process method for graphene electrode can be provided, and the lithiated graphene electrode can be used as a negative electrode of a lithium ion battery or a negative electrode of a supercapacitor lithium battery. The porous graphene substrate can be used as a negative electrode of a lithium ion battery. An electrode plate of a supercapacitor.
