METHOD FOR MAKING PHOSPHATE-BASED ELECTRODE ACTIVE MATERIALS

摘要

The invention is directed to synthesizing a phosphate-based electrode active material. The method includes the step of reacting two or more starting materials collectively containing at least a PO3 3-anion, an alkali metal and a metal which is redox active in the final reaction product, at a temperature and for a time sufficient to form the phosphate-based electrode active material.
