  • METHOD FOR FORMING COMPOSITE OXIDE, POSITIVE ELECTRODE, LITHIUM-ION SECONDARY BATTERY, ELECTRONIC DEVICE, POWER STORAGE SYSTEM, AND MOVING VEHICLE
    Publication number: 20240145687
    Abstract: A novel positive electrode active material, a novel positive electrode, and a novel lithium-ion secondary battery are to be provided. The lithium-ion secondary battery includes a positive electrode, a negative electrode, and an electrolyte. The positive electrode includes a positive electrode active material that includes a composite oxide containing lithium and cobalt. The positive electrode active material includes barium, magnesium, and aluminum in a surface portion. When being analyzed, the surface portion preferably includes a region where a first point of the highest barium concentration and a second point of the highest magnesium concentration exist closer to the surface than a third point of the highest aluminum concentration does.
