<P>PROBLEM TO BE SOLVED: To provide a positive electrode for a lithium-ion secondary battery that is excellent in high-temperature storage characteristics, uniformity of a positive-electrode mixture layer, durability, and productivity, to provide a method of manufacturing the same, and to provide a lithium-ion secondary battery using the positive electrode. <P>SOLUTION: The positive electrode for the lithium-ion secondary battery includes: a positive electrode active material containing a lithium composite oxide; a positive electrode mixture layer containing a conductive material and a binder; and a current collector. The positive electrode mixture layer contains a compound including sulfur (S) and/or phosphorous (P), a first polymer serving as a main binder, and a second polymer different from the first polymer. The method uses a positive-electrode active material in which a compound including sulfur (S) and/or phosphorous (P) is deposited on the surface of a lithium composite oxide. <P>COPYRIGHT: (C)2009,JPO&INPIT |
