ELECTRODE PLATE FOR LITHIUM ION SECONDARY BATTERY, LITHIUM ION SECONDARY BATTERY USING ELECTRODE PLATE FOR LITHIUM ION SECONDARY BATTERY, METHOD OF MANUFACTURING ELECTRODE PLATE FOR LITHIUM ION SECONDARY BATTERY

PROBLEM TO BE SOLVED: To provide an electrode for a lithium ion secondary battery with excellent charge/discharge cycle characteristics in which a structural component composition ratio such as a binder ratio and active material ratio are optimized depending on a position in the electrode. SOLUTION: The electrode plate includes a collector 1a and a mixture layer 2a formed at least on one surface of the collector. The mixture layer is formed of a plurality of structural components containing an electrode active material 3a for storing and emitting lithium ions and a binder 4a. The electrode plate for the lithium ion secondary battery is used wherein the mixture layer 2a is formed by controlling to have parts with different structural component compositions from each other in the mixture layer.
