Abstract
An electrode comprising a porous metal member in sheet form having a three-dimensional skeleton structure and a solid polymer electrolyte is used to construct a lithium secondary battery and an electric double-layer capacitor. Owing to the increased retaining force of the gel electrolyte component to a current collector, the gel electrolyte component can be directly applied to the current collector, contributing to mass scale productivity and cost reduction.
