PROBLEM TO BE SOLVED: To provide such a battery as being excellent in its discharging cyclic characteristic by chemically processing the negative electrode of a battery employing lithium as an active substance, having halogen gas included in non- aqueous electrolyte so as to form a coating film of high lithium ion. SOLUTION: Occlusion/discharge of lithium ions is efficiently achieved, charging/discharging efficiency in a negative electrode can be improved through this coating film and a charging/discharging cyclic characteristic is improved. As a material to constitute this load use of metallic lithium, lithium alloy, a carbonic material such as graphite, etc., capable of storing/releasing lithium ions can be intended. Furthermore, as a positive pole material, a lithium transition complex oxide can be used. As a solvent of non-aqueous electrolyte, ethylene carbonate, and as a solvent, LiPF6 , etc., can be used. |
