MANUFACTURE OF POSITIVE ELECTRODE FOR NONAQUEOUS SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode having high conductivity of an active material with a current-collector with no particular treatment on metal foil. SOLUTION: In this manufacturing method of the electrode for a nonaqueous secondary battery using lithium manganate as a positive electrode active material, the portion of more than 80 wt.% of the lithium manganate has the average particle size of 20-50 μm. And this manufacturing method has a positive electrode mixture preparation process in which a binder is compounded in the lithium manganate to form them into paste, an embrocation and dry process in which the paste positive electrode mix is embrocated on a current-collector composed of metal foil and it is dried, and a pressure-forming process in which the positive electrode layer formed on the current-collector is pressure-formed such that thickness of the positive electrode layer is set beyond 1/2 and less than 4/5.
