Abstract
A lithium polymer secondary battery which comprises a negative electrode, a positive electrode, and polymer electrolyte layers united respectively with the two electrodes and differing in viscoelastic behavior. In this battery, conformation to the expansion and shrinkage accompanying charge/discharge is easy and the interfacial resistance between each electrode and the polymer electrolyte is kept low.
