ABSTRACT:
The present invention provides a polymer secondary battery comprising a pair of current collectors and electrodes arranged in opposed relationship with an electrolyte solution-containing separator or a solid electrolyte interposed therebetween, the polymer secondary battery having a structure in which a first polymer active material layer adjacent to the current collector of the negative electrode has laminated thereto at least one layer of a polymer material having an oxidation-reduction potential higher than that of the first polymer active material layer. This polymer secondary battery has a high rate of appearance of capacity, is capable of quick charging and discharging, and exhibits excellent cycle characteristics.
