NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND METHOD FOR PRODUCING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode and a nonaqueous electrolyte. The positive electrode includes LixMnaNibCOcMdO2 (0<x<1.3, 0.1<a<0.7, 0.1<b<0.6, 0.1<c<0.67, 0≦d<0.1, a+b+c+d=1, and M represents a metal selected from the group consisting of Al, Ti, Mq, Cr, Zn, W, Zr and Nb) as a positive active material. The nonaqueous electrolyte includes a cyclic disulfone compound of the general formula (1) in an amount of 0.1 to 4.0% by mass based on the total mass of the nonaqueous electrolyte. |

1. A nonaqueous electrolyte secondary battery comprising:
a positive electrode; a negative electrode; and a nonaqueous electrolyte, wherein the positive electrode includes LixMnaNibCOcMdO2 (0<x<1.3, 0.1<a<0.7, 0.1<b<0.6, 0.1<c<0.67, 0≦d=0.1, a+b+c+d=1, and M represents a metal selected from a group consisting of Al, Ti, Mg, Cr, Zn, W, Zr and Nb) as a positive active material, and the nonaqueous electrolyte includes a cyclic disulfone compound of a following general formula (1) in an amount of 0.1 to 4.0% by mass based on a total mass of the nonaqueous electrolyte:wherein R1 and R2 each represent hydrogen, or an alkyl group having 2 to 4 carbon atoms, optionally including a halogen element. |
