Lithium ion secondary battery |
abstract |
Redox decomposition of non-aqueous electrolyte in a lithium ion secondary battery using a positive electrode active material containing lithium (Li) and tetravalent manganese (Mn) and comprising a lithium manganese-based oxide whose crystal structure belongs to a layered rock salt structure Suppresses deterioration caused by As the nonaqueous solvent and / or electrolyte salt of the nonaqueous electrolytic solution, one containing fluorine (F) is used. Further, SiO x (0.3 ≦ x ≦ 1.6) is used as the negative electrode active material. By using together the non-aqueous electrolyte containing fluorine and SiO x as the negative electrode active material, deterioration due to redox decomposition of the non-aqueous electrolyte can be suppressed. |
