  • CATHODE ACTIVE MATERIAL FOR LITHIUM-ION BATTERY (LIB) AND PREPARATION METHOD THEREOF
    Publication number: 20230268488
    Abstract: The present disclosure discloses a cathode active material for a lithium-ion battery (LIB), including a matrix of the cathode active material for the LIB and a sulfur-containing compound, where a mass of S in the sulfur-containing compound is 0.06% to 0.40% of a total mass of the cathode active material for the LIB; and the sulfur-containing compound is distributed in the form of a sulfate in the cathode active material for the LIB. A preparation method of the cathode active material for the LIB includes: mixing the matrix of the cathode active material and the sulfur-containing compound (or a precursor of the cathode active material, a lithium source, and the sulfur-containing compound), and subjecting a resulting mixture to calcination to obtain the cathode active material for the LIB.
