  • POSITIVE ELECTRODE PLATE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, POSITIVE ACTIVE MATERIAL TO BE USED THEREFOR, AND SECONDARY BATTERY USING THE SAME
    Publication number: 20190088943
    Abstract: A positive electrode plate for a nonaqueous electrolyte secondary battery, which enables an increased output of a battery and leads to decreased deterioration in battery performance when used as a positive electrode plate for the battery, is provided. The positive electrode plate for a nonaqueous electrolyte secondary battery is provided, which has a positive electrode composed of a positive active material comprising a lithium metal composite oxide, and on the surface of the positive electrode, an amorphous coating layer formed of a compound containing niobium and lithium, wherein the compound is a lithium ion conductor. Accordingly, lithium ion conductivity in the electrode can be improved, and deterioration of the lithium ion conductivity and dielectricity in air can be suppressed.
