| 摘要 |
An electrode material includes Fe-containing olivine-structured LixAyDzPO4 (wherein A represents one or more elements selected from the group consisting of Co, Mn, Ni, Cu, and Cr; D represents one or more elements selected from the group consisting of Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, Y, and rare earth elements; 0<x≦2; 0<y≦1; and 0≦z≦1.5) particles that are coated with a carbon coating film, in which an abundance of Fe is 0.01 to 0.1 mol with respect to 1 mol of LixAyDzPO4, and an abundance ratio (Fe/(Fe+A+D)) of Fe on surfaces of the LixAyDzPO4 particles is 0.02 to 0.25. |
