<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having high capacity wherein the quantity of conductive assistant is sharply reduced by reducing the resistivity of an active material. <P>SOLUTION: The active material is a complex phosphate of lithium and transition metal containing nitrogen atom. The transition metal is at least one kind of atom selected from Fe, Co, Ni, and Mn. The nonaqueous electrolyte secondary battery uses the above activator either for a cathode or for an anode. The active material is synthesized by making the phosphate compound react with ammonia gas after heating the phosphate compound under reductive atmosphere. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
