PURPOSE:To improve the reversibility of charge and discharge by using an alkyl derivative of 1,3-dioxolan as the electrolytic solvent. CONSTITUTION:Alkyl derivatives of 1,3-dioxolan such as 4-methyl-1,3-dixolan 4,4-dimethyl-1,3-dioxolan, 4,5-dimethyl-1,3-dioxolan, 2-methyl-1,3 dioxolan, 2,4,5- trimethyl-1,3-dioxolan are used as the electrolytic solvent. These alkyl derivatives of 1,3-dioxolan are used individually by combining the two types with each other or combining them with other organic solvents. In this case, for example, 1,2-dimethoxyethane, propylenecarbonate, gamma-butyrolactone, tetrahydrofuran, and such are used as another organic solvent. |
