LITHIUM ION SECONDARY BATTERY POSITIVE ELECTRODE MATERIAL, LITHIUM ION SECONDARY BATTERY POSITIVE ELECTRODE MEMBER, AND LITHIUM ION SECONDARY BATTERY |
摘要 |
Provided is a lithium ion secondary battery positive electrode material containing an oxide represented by the composition formula Li2-xMII yM(Si,MB)O4 (wherein MII is a divalent element. M is one or more elements chosen from the group consisting of Fe, Mn, Co and Ni. MB is an element that is an arbitrary component which substitutes Si in order to make up, as necessary, the difference between the charge of [Li2]2+ and the charge of [Li2-xMII y]n+), wherein, in the composition formula, -0.25<x@0.25 and 0<y@0.25. Further, a lithium ion secondary battery positive electrode member which uses the lithium ion secondary battery positive electrode material, and a lithium ion secondary battery are provided. |
