Lithium polymer battery with a crosslinked electrolyte

A lithium polymer secondary cell having a negative electrode, a positive electrode and, arranged between the electrodes, a polymer electrolyte layer, characterized in that the cell has been subjected to a heat treatment at a temperature of 40 to 60&#xb0; C. after the assembly thereof. The polymer cell is freed of or is reduced in the adverse effect of a residual monomer and initiator on the performance of the cell. The polymer electrolyte is formed by cross-linking polymerization of a precursor monomer for an ion conducting polymer in a non-aqueous electrolyte, and the residual monomer and initiator contained therein is consumed by the heat treatment.

Lithium polymer secondary battery and method for manufacturing the same

In a lithium secondary cell having a negative electrode, a positive electrode and, arranged between the electrodes, a polymer electrolyte layer, the internal resistance of the cell and the interfacial resistance between the electrode and the polymer electrolyte can be reduced by incorporating into the electrode, in advance, a polymer electrolyte precursor solution in a manner such that the electrode has a higher content of the precursor monomer and/or an oligomer thereof than that in the polymer electrolyte layer formed on the electrode.

The polymer electrolyte has a two-layer structure composed of a positive-electrode-side layer and a negative-electrode-side layer. The polymer electrolyte on the positive-electrode side contains a nonaqueous electrolytic solution containing a lithium salt in a higher concentration than that in the polymer electrolyte on the negative-electrode side. The battery is improved in charge/discharge cycling characteristics and high-load discharge characteristics.
