NON-AQUEOUS ELECTROLYTE SOLUTION FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME |
摘要 |
A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and a carbonate organic solvent. The non-aqueous electrolyte solution further includes a fluoro group-containing sulphonate compound expressed by Chemical Formula 1. When the non-aqueous electrolyte solution is employed for a lithium secondary battery, low-temperature discharging characteristics and life cycle characteristics are greatly improved. Also, even though a battery is stored at a high temperature in a fully-charged state or a charging/discharging process is under progress, the decomposition reaction of a carbonate-based organic solvent is restrained, thereby solving the swelling problem and improving high-temperature life cycle characteristics.
