CATHODE ACTIVE MATERIAL, CATHODE AND NONAQUEOUS SECONDARY BATTERY |
| 摘要 |
A cathode active material of the present invention is a cathode active material having a composition represented by General Formula (1) below, LiFe1-xMxP1-ySiyO4 (1), where: an average valence of Fe is +2 or more; M is an element having a valence of +2 or more and is at least one type of element selected from the group consisting of Zr, Sn, Y, and Al; the valence of M is different from the average valence of Fe; 0<x≰0.5; and y=x×({valence of M}−2)+(1−x)×({average valence of Fe}−2). This provides a cathode active material that not only excels in terms of safety and cost but also can provide a long-life battery.
