MANUFACTURING METHOD OF LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To reduce a resistance of an electrode and an interface resistance with a polymer electrolyte layer, related to manufacturing of a lithium secondary battery comprising a polymer electrolyte layer, by improving infiltration/ percolation of ion conductive polymer holding a nonaqueous electrolyte into an electrode and a separator base material, if it is used. SOLUTION: The nonaqueous electrolyte or that containing a little precursor of ion conductive polymer is allowed to infiltrate into a negative electrode and a positive electrode as well as a separator base material, if it is used, in advance. Then a polymer electrolyte layer is formed which is arranged between the negative electrode and the positive electrode.
