Aktives Material für eine Kathode, Kathode, nichtwässrige Sekundärbatterie, Modul und Energiespeichersystem |
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. |
