BATTERY, METHOD OF MANUFACTURING THE SAME AND NON-AQUEOUS SECONDARY BATTERY USING THE SAME

摘要

To provide an electrode plate capable of retaining a larger amount of active material and having a composite material layer uniform in thickness, a positive electrode plate (6) or a negative electrode plate (7) is formed by laminating a composite material layer (1) of the active material on a surface of a current collector plate (2) in strip form. A slope in a thickness direction (X/Z) of the end surfaces of the composite material layer (1) along the longer sides of the current collector plate (2) is“0<(X/Z)≰1”.
