摘要： PROBLEM TO BE SOLVED: To provide a secondary battery capable of improving cycle characteristics and charging load characteristics. SOLUTION: The secondary battery has a positive electrode 21, a negative electrode 22, and an electrolyte, and the electrolyte is impregnated into a separator 23 arranged between the positive electrode 21 and the negative electrode 22. A negative electrode active material of the negative electrode 22 includes a negative electrode material (high electrical potential material) which occludes and emits lithium ions at an electrical potential of 1.0V or more to a lithium potential. A solvent of the electrolyte includes carbonic acid ester having two or more of halogens as a constituent element. A film can be easily formed on the surface of the negative electrode 22 even when the high electrical potential material is used as a negative electrode active material. Thus, decomposition reaction of the electrolyte is restrained at the time of charge and discharge, and an acceptance nature of lithium ions on the negative electrode 22 is improved.

摘要： PROBLEM TO BE SOLVED: To provide a secondary battery capable of improving cycle characteristics. SOLUTION: The secondary battery includes a positive electrode 21 and a negative electrode 22 as well as an electrolyte, and electrolytic solution is impregnated in a separator 23 installed between the positive electrode 21 and the negative electrode 22. The negative electrode 22 has a negative electrode film 22C on a negative electrode active material layer 22B installed on a negative electrode current collector 22A, and the negative electrode film 22C contains a radical capture compound.
