PURPOSE:To enhance the discharge capacity and discharge voltage of a nonaqueous battery by using lithium or a material capable of storing lithium therein as the positive material of a negative electrode, and electrochemically charging a lithium-contained manganese dioxide as the active material of a positive electrode so as to form the nonaqueous battery. CONSTITUTION:Lithium or a material capable of storing lithium therein is used as the active material of a negative electrode and a manganese oxide containing lithium is obtained by heat treatment of manganese dioxide and a lithium salt at 150 to 430 deg.C and is electrochemically charged with electricity to form the active material of a positive electrode, thereby forming a nonaqueous battery. The active material of the positive electrode has peaks near 2theta=37 deg. and 2theta=38 deg. in an X-ray diffraction diagram by CuKalpha. Thereby the capacity and energy density of the nonaqueous battery are both enhanced and also the charge and discharge cycle characteristic of the battery can also be enhanced. |
