NON-AQUEOUS ELECTROLYTE SOLUTION FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME |
摘要 |
The present invention relates to a non-aqueous electrolyte solution for a lithium secondary battery, comprising a sulfolane-based additive; and a lithium secondary battery using the same. The non-aqueous electrolyte solution for a lithium secondary battery according to the present invention comprises an ionizable lithium salt; an organic solvent; and a sulfolane compound of formula (I), the sulfolane compound being present in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the total weight of the lithium salt and the organic solvent. The non-aqueous electrolyte solution for a lithium secondary battery according to the present invention can exhibit superior storage characteristic and life cycle at a high temperature, with maintaining good output characteristic at a low temperature. |
