NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
The present invention provides a nonaqueous electrolyte secondary battery. The nonaqueous electrolyte secondary battery comprises a Positive electrode containing a Positive electrode active material capable of being doped and dedoped with alkali metal ions and represented by formula A x M y PO 4 , and a negative electrode. In the above formula, A is one or more alkali metal elements, M is one or more transition metal elements, x is more than 0 and not more than 1.5, y is from 0.8 to 1.2, and the positive electrode active material is obtained by bringing a P source, an A source, an M source and water into contact with each other to obtain a liquid material containing A x M y PO 4 and then evaporating water from the liquid material. |
