（：検討されている。BACKGROUND ART Non-aqueous electrolyte batteries using negative electrodes made of lithium or lithium alloys have attracted attention because they have the advantage of having high energy density and low self-discharge. In particular, if cupric oxide is used as the positive electrode active material, the battery voltage will be about 1.5V, and it can be used interchangeably with existing alkaline dry batteries, mercury batteries, silver batteries, etc., so it has become popular in recent years. has been done.

Problems to be Solved by the Invention However, when producing lithium-containing cupric oxide 7 by the above production method, the oxide produced by the thermal decomposition reaction of 0uOO3 Since the reaction is between copper 2 (CUO) and L120, it is not necessarily the case that copper (Ou) and lithium (Ll) share the same -lS2 element. Therefore, Li

ある。Further, the CuO obtained by this method has a structure in which Ll does not penetrate into the inside of the OuO crystal, and Ll is dissolved only on the CuO surface. Therefore, the effect of promoting the diffusion of Ll is effective only in the early stage of discharge. Therefore, although the drop in the initial voltage can be resolved, there is a problem that at the end of discharge C, the performance of the heavy oil deteriorates.
