    摘要： In a lithium ion secondary battery using a positive electrode active material made of a lithium manganese based oxide that contains Li and tetravalent Mn and having a crystal structure known as a layered rock salt structure, oxidative and reductive degradation of the non-aqueous electrolyte solution is reduced.The battery uses a non-aqueous electrolyte solution containing fluorine in one or both of the non-aqueous solvent and the electrolytic salt. For the negative electrode active material, SiOx (0.3≦x≦1.6) is used. The combined use of the non-aqueous electrolyte solution containing fluorine and SiOx in the negative electrode active material reduces oxidative and reductive degradation of the non-aqueous electrolyte solution.
