(57) [Summary] [PROBLEMS] To prevent deterioration of battery capacity characteristics, cycle characteristics, and energy density characteristics. SOLUTION: A positive electrode 2, a negative electrode 3, a separator 4, and an electrolytic solution are provided, and a lithium compound generated by mixing two or more kinds of solutions of the negative electrode active material of the negative electrode 3 is supported on the surface of the negative electrode carrier. It consists of a negative electrode carrier, and since the lithium compound prevents the deterioration of the negative electrode, the battery capacity characteristics, Prevents deterioration of cycle characteristics and energy density characteristics. |
