<P>PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery which has large energy density per unit volume and satisfactory life performance. <P>SOLUTION: This nonaqueous secondary battery uses particles, as a positive electrode active material, which are formed by flocculating the primary particles of a lithium manganese compound oxide and the primary particles of a lithium nickel compound oxide, the average diameter of the primary particles of the lithium manganese compound oxide being larger than that of the lithium nickel compound oxide. <P>COPYRIGHT: (C)2003,JPO |
