複合正極活物質の製造方法および複合正極活物質
Document Type and Number:
Japanese Patent JP6627695
Kind Code:
B2
Abstract:
Provided in the present disclosure is a method for producing a composite cathode active material with low reaction resistance. The method comprises: a coating step of, with a Li ion conductive oxide, coating a cathode active material that is a spinel type oxide including at least a Mn having a valence of +4 to obtain a coated cathode active material; and a heat treating step of heat treating the coated cathode active material to obtain a composite cathode active material; wherein a valence of the Mn in the cathode active material is lower than a valence of the Mn in the cathode active material before coating, and a valence of the Mn is increased by the heat treating.
