PURPOSE: To enhance the storage stability and cycle characteristic of a battery by using an electrolyte with high conductivity, high thermal stability, and high oxidation stability. CONSTITUTION: LiC(R<1> SO2 )(R<2> SO2 )(R<3> SO2 ) represented by LiC(CF3 SO2 )3 , LiN(R<4> SO2 )(R<5> SO2 ) represented by LiN(CF3 SO2 )2 , or LiR<6> SO3 represented by LiCF3 SO3 wherein R<1> , R<2> , R<3> , R<4> , R<5> , and R<6> independently show Cn X2n+1 (n is 1-8, X is a hydrogen atom or a halogen atom.)} and LiPF6 , LiBF4 , LiClO4 , or LiAsF6 are jointly used as the electrolyte of a nonaqueous electrolyte. The cycle characteristic and storage stability of a battery are enhanced. |
