Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a light-weighed lithium ion secondary battery and a positive electrode thereof in which a charge capacity is largely maintained and a charge capacity density and a weight energy density are enhanced. SOLUTION: A positive electrode of a lithium ion secondary electrode is constituted by mixing a LiMn2O4 powder and a large charge capacity positive electrode active substance powder.

The positive electrode can be also constituted as the lithium ion secondary electrode by combining it with a negative electrode constituted by a carbon material.  Thereby, since a irreversible capacity part is compensated by the large charge capacity positive electrode active substance and an addition amount thereof is small, a light weight of the positive electrode and the battery is realized and the charge capacity density in the battery is enhanced.
