ELECTRODE PLATE FOR NON-AQUEOUS SECONDARY BATTERY AND NON-AQUEOUS SECONDARY BATTERY USING SAME

摘要

An electrode plate for a non-aqueous secondary battery. Said electrode plate is provided with a rectangular collector and a mixture layer that is formed on the surface of the collector and contains a first active material. The mixture layer has: a first edge section that runs along one edge of the collector; a second edge section on the opposite side from the first edge section; a third edge section that runs along an edge of the collector perpendicular to the aforementioned one edge; a fourth edge section on the opposite side from the third edge section; and a main section consisting of the area that is not part of the first through fourth edge sections. At least one prescribed edge section selected from the group consisting of the first through fourth edge sections is thinner than the main section of the mixture layer. The surface of the prescribed edge section(s) is covered by a surface layer containing a second active material that is more reactive with respect to lithium than the first active material is.
