ABSTRACT:
A lithium polymer secondary battery comprising a negative electrode, a positive electrode and an electrolyte layer between both electrodes, wherein the negative electrode and the positive electrode each has a solid electrolyte prepared by incorporating an organic electrolytic solution into a polymer, the polymer is obtained by solidifying a precursor solution containing vinylene carbonate and a content of vinylene carbonate in the precursor solution for the positive electrode is smaller than that in the precursor solution for the negative electrode.
