MANUFACTURING METHOD OF GEL ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To make the movement of lithium ion sufficient by enhancing the adhesion between an electrode active substance layer and gel electrolyte. SOLUTION: A manufacture of gel electrolyte battery in which a battery element is accommodated in a sheath material consisting of laminate film, and which is enclosed by heat welding has followings; a battery element manufacturing process in which a positive electrode and a negative electrode are laminated via a gel electrolyte to form the battery element; a housing process in which the battery element is housed in a laminate film; and a heat-treatment process in which a heat-treatment is applied to the battery element that has been housed in the laminate film.
