ELECTRODE ACTIVE MATERIAL AND USE THEREOF

摘要

Disclosed is an electrode active material which mainly contains a metal phosphate complex and exhibits good charge/discharge characteristics. Also disclosed is a method for producing such an electrode active material. The electrode active material mainly contains an amorphous metal complex represented by the general formula: AxM(PO4)y. In the formula, A represents an alkali metal, M represents one or more metal elements selected from transition metals, 0 = x = 2 and 0 < y = 2. Such an electrode active material can be produced at a lower cost and in a shorter time than the conventional electrode active materials using a crystalline metal complex, and still exhibits battery characteristics equivalent to those of the conventional electrode active materials.
