ELECTRODE MATERIAL FILM-FORMING METHOD, FILM OF ELECTRODE MATERIAL AND ELECTRODE MATERIAL, NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND INJECTION PROCESSING DEVICE FOR ELECTRODE MATERIAL FILM FORMING

摘要

PROBLEM TO BE SOLVED: To provide an electrode material film-forming method hardly causing interfacial delamination and solid fine particle falling, and stably ensuring a charge/discharge cycle number.

SOLUTION: A solid fine particle G generated from a first material capable of forming a lithium compound and an electro-conductive second material by mechanical alloying is used. The solid fine particles G are ejected through a nozzle 120 riding on a jet stream into collision with and adhesion to an electrode base material W disposed facing the nozzle 120 to form a film of the electrode material using the first material as an active substance on the electrode base material W.
