ELECTRODE PLATE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, NONAQUEOUS ELECTROLYTE SECONDARY BATTERY USING SAME, AND MANUFACTURING METHOD FOR SAME

摘要

The core surface of this electrode plate for a nonaqueous electrolyte secondary battery is provided with an electrode active material layer having an electrode active material and a binder. The electrode plate for a nonaqueous electrolyte secondary battery is characterized by the electrode active material layer having a section with the least amount of binder in the central region in the thickness direction of the electrode active material layer, and by the binder being distributed so that the amount of the binder contained in the electrode active material layer continuously increases from said section towards the core side and the outer surface side. Preferably, if the amount of binder per unit thickness of the electrode active material layer is 10 when the binder is assumed to be uniformly distributed, the amount of binder per unit thickness of the electrode active material layer at the region 10% in depth from the outer surface of the electrode active material layer is regulated to be greater than 10.
