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.
Claims16
An electrode comprising a porous metal member in sheet form having a 3-dimensional reticulated skeleton structure and a coating comprising a solid polymer electrolyte and an active material, wherein said porous metal member has a porosity of 80 to 98% and mean maximum pore diameter of 100 to 800 μm.
