Abstract
A cathodic active material for a nonaqueous electrolyte secondary battery according to the invention includes a lithium-containing transition metal phosphate containing Li and a transition metal. A transition metal site and P site of the lithium-containing transition metal phosphate are replaced by elements other than elements contained in the lithium-containing transition metal phosphate, and the quantity of P site is excessive with respect to a stoichiometric proportion of the lithium-containing transition metal phosphate. With this cathodic active material, a high-power and high-capacity secondary battery which is superior in safety and cost and has superior rate performance can be provided.
