METHOD OF MANUFACTURING ACTIVE MATERIAL |
| 摘要 |
According to an embodiment, a method of manufacturing an active material is provided. The active material includes particles of a composite oxide of the general formula Ti1±xNb2±yMzO7−δ and a carbon-including phase. Here, 0≦x≦0.15, 0≦y≦0.3, 0.01<z≦0.2, and 0<δ<0.3. M is at least one of Mg, Fe, Ni, Co, W, Ta, and Mo. The manufacturing method includes preparing a mixture by mixing in a liquid, a compound including Ti, a compound including Nb, a carbon source, and a compound including an element M, obtaining a precursor from the mixture, and calcining the precursor. The calcination is performed in a mixed atmosphere including nitrogen and oxygen, or argon and oxygen, with an oxygen concentration of 5% to 15%. |

1. A method of manufacturing an active material including particles of a composite oxide represented by a general formula Ti1±xNb2±yMzO7−δ (M is at least one element selected from the group consisting of Mg, Fe, Ni, Co, W, Ta, and Mo, and each subscript satisfies 0≦x≦0.15, 0≦y≦0.3, 0.01<z≦0.2, and 0<δ<0.3) and a carbon-including phase formed on the surface of the particles, the method comprising:
preparing a mixture by mixing in a liquid, a compound including Ti, a compound including Nb, a carbon source, and a compound including the element M; obtaining a precursor including Ti, Nb, M, C, and O from the mixture; and calcining the precursor in a mixed atmosphere including nitrogen and oxygen, or argon and oxygen, where an oxygen concentration of the mixed atmosphere is 5% to 15%. |
