METHOD TO MANUFACTURE ACTIVATE SUBSTANCE FOR POSITIVE ELECTRODE AND METHOD OF MANUFACTURING NON AQUEOUS ELECTROLYTE CELL |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a LiFePO4 in a high yield without generating a toxic byproduct in a baking process. SOLUTION: The method to manufacture a positive electrode active substance represented in the formula LixFePO4 (0<x<=1) is composed of a mixing process to make a precursor, by mixing Li3PO4 and Fe3(PO4)2 or its hydrate, Fe3(PO4)2.nH2O (n is hydration number) and a baking process to bake the precursor available in the mixing process. |
