Provided is a lithium-ion rechargeable battery electrode, which has a high discharge capacity, excellent adhesion between a positive electrode active material and a conductive material and a positive electrode current collector, and excellent cycle characteristics that are not prone to degradation even when a charge-discharge cycle is repeated. The lithium-ion rechargeable battery electrode has a positive electrode active material layer containing a positive active material, binder and conductive material formed on a surface of the positive electrode current collector. The positive electrode active material contains a lithium-containing complex oxide that contains an Li element, and at least one type of transition metal element selected from a group comprising Ni, Co and Mn (where the molar quantity of the Li element is 1.2-fold the total molar quantity of said transition metal element(s)). The binder contains a fluorine-containing rubber, which comprises a copolymer having repeating units based on at least one type of monomer selected from a group comprising tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride, and a fluorine content of 50-76 mass %. |
