PROBLEM TO BE SOLVED: To provide a positive active material in which capacity is high, cost is low, and an increase with passage of time in interface polarization resistance is small, and realize a nonaqueous electrolytic secondary battery with small internal resistance and high charge energy efficiency by using the positive active material. SOLUTION: The surface of a nickel-containing, lithium-containing compound oxide is covered with a compound containing either one of Co, Al, and Mn. As the compound for covering the surfaces of the compound oxide particles, a metal alcoxide containing either one of Co, Al, and Mn is practically listed. |
