Patent ID: 7482092

Claim:
A polymer battery comprising: at least one layer of a positive electrode, the positive electrode being in thin film form and comprising a positive active material layer formed on a positive electrode collector; at least one layer of a separator retaining a polymer electrolyte; and at least one layer of a negative electrode, the negative electrode being in thin film form and comprising a carbon material as an active substance; wherein an entirety of the outer peripheries of the separator and of the negative electrode is positioned outside of an outer periphery of the positive electrode except for a collector tab provided to the positive electrode so as to protrude from one side of the positive electrode; wherein an outer periphery of the separator is positioned outside of an outer periphery of the positive electrode, and an outer periphery of the negative electrode is positioned outside of the outer periphery of the separator; and wherein a distance D 1 between an end of the negative electrode and an end of the positive electrode is greater than a distance D 2 between the end of the negative electrode and an end of the separator; and wherein the positive electrode, the negative electrode, and the separator which retain a polymer electrolyte have adhesiveness for retaining their own weight.
