▎ 摘　　要

NOVELTY - The method involves uniformly dispersing the active material, conductive agent and binder into the solvent to obtain a slurry. The slurry is applied evenly on the current collector according to a certain surface density. The film-forming additive directly above the coated slurry is vertically injected into the slurry through micropores using high-pressure gas. The dried pole sheet is obtained after being dried in an oven. The dried pole sheet is rolled to obtain the product porous pole sheet. USE - Manufacturing method for porous pole sheet of lithium-ion battery (claimed). ADVANTAGE - The manufacturing method can form pores perpendicular to the electrode on the electrode, reduce the transmission distance of lithium ions, and increase the rate performance, cycle performance and charging speed of the battery. The film-forming additive can fully react with the electrode to form an solid electrolyte interphase (SEI) film by adding the positive electrode film-forming additive to the positive electrode and the negative electrode film-forming additive to the negative electrode. The porous pole sheet has higher use efficiency, can reduce the amount of film-forming additives used, and reduce costs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium-ion battery.
