The positive electrode of the lithium cobalt oxide battery is lithium cobalt oxide (LiCoO2), the negative electrode is graphite (C), and the electrolyte is solution lithium salt. The electrode reaction formula is as follows:
1. Positive electrode reaction formula: LiCoO2+Li++e-→LiCoO2?Li+.
2. Negative electrode reaction formula: LiC6→Li++C6+e-.
