▎ 摘　　要

NOVELTY - The method involves providing electroactive particles. The electroactive particles are mixed with a graphene-based material to form a composite. The composite is spray-coated onto a substrate to form a battery electrode, where a percentage of the electroactive particles to the graphene-based material is 40-95 wt, where the mixing step and spray coating step are performed repeatedly by replacing different composite to form multiple layers on the substrate, and the substrate is heated to 50-100 degree before spray coating. USE - Method for preparing a battery electrode in versatile applications e.g. printed electronics i.e. touch-panel and flexible electronics such as solar cell and organic light-emitters for use in portable electronic devices and electric vehicles. ADVANTAGE - The method enables providing an efficient operation to obtain a high quality, cost-effective and scalable product to serve as a cathode. The method enables utilizing a lithium sulfur battery to provide better electrochemical performance after charge-discharge. The method enables easily controlling thickness of sprayed materials. The method enables easily evaporating organic solvents from the composite material by slow heating without containing residual solvents. DETAILED DESCRIPTION - The electroactive particles are sulfur and molybdenum disulfur. The substrate is a current collector. The current collector is made by graphene electrodes that are electrochemically exfoliated graphene. An INDEPENDENT CLAIM is also included for a battery electrode.
