言えなかった。Batteries using layered compounds such as MnB<34, fluorinated graphite, and oxyhalides such as benzoquinones and dinitrobenzene have been proposed. Specifically, for example, batteries are known that use graphite and fluorine intercalation compounds as positive electrode active materials, and lithium metal as negative electrode active materials (
(See U.S. Pat. No. 3,514,337). Also,

However, these batteries have the disadvantage that they are not rechargeable and cannot be used as secondary batteries.
