▎ 摘　　要

NOVELTY - The method involves forming a thick multilayer electrode on a current collector by forming a set of electrode units to form an electrode stack on the current collector, where each electrode unit of electrode assemblies comprise an electroactive material layer that contains a set of electroactive particles. A layer of a conductive interface material is arranged with a set of graphene nanoparticles, where thickness of the electrode stack is greater than or equal to about specified microns. A precursor of the layer of conductive interface material is applied to a target surface. USE - Method for making a thick multilayer electrode of an electrochemical cell i.e. lithium-ion battery. ADVANTAGE - The method enables withstanding the electrode without suffering damage, and increasing loading density of electroactive materials to increase overall energy density of cells. The method enables increasing storage capacity and reducing size of a battery while maintaining similar cycle life to lithium-ion batteries.
