摘要:
A positive electrode material is disclosed which contains an iron lithium phosphate as a positive electrode active material and has a large charge/discharge capacity, high-rate adaptability, and good charge/discharge cycle characteristics at the same time. Also disclosed are a simple method for producing such a positive electrode material and a high-performance secondary battery employing such a positive electrode material. Specifically, disclosed is a positive electrode material for secondary battery characterized by mainly containing a positive electrode active material represented by the general formula: LinFePO4 (wherein n is a number of 0-1) and further containing at least one different metal element selected from the group consisting of vanadium (V), chromium (Cr), copper (Cu), zinc (Zn), indium (In) and tin (Sn). This positive electrode material can be produced using a halide of such a metal element as the raw material.
