Fast charging solution and adhesion solution - graphene coated aluminum foil

Graphene-coated foil - As a lithium-ion battery substrate, it is mainly composed of a binder and graphene. Through graphene's excellent theoretical conductivity (106S/m) and thermal conductivity (5000w/m.k: X-Y plane), it can effectively collect the electrical energy and heat generated during the charging and discharging process of the electroactive material.
