摘要：
An electrolytic solution for a lithium battery includes a lithium salt, an organic solvent; a disultone-based compound represented by Formula 1, and a non-polar unsaturated group-containing cyclic carbonate-based compound: wherein, in Formula 1, A1 to A4 are each independently a substituted or unsubstituted C1-C5 alkylene group, a carbonyl group, or a sulfinyl; n1 to n4 are each independently an integer 1 to 3, and when n1 to n4 are each independently two or greater, a respective plurality of any of A1s to A4s are identical to or different from each other. When the lithium battery includes the electrolyte solution, room-temperature and high-temperature lifespan characteristics of the lithium battery may improve.
摘要（中）：
锂电池用电解液包括锂盐，有机溶剂， 由式1表示的二元酮类化合物和非极性不饱和基团的环状碳酸酯系化合物，式中，A1〜A4各自独立地为取代或未取代的C1-C5亚烷基，羰基 ，或亚磺酰基; n1〜n4各自独立地为1〜3的整数，当n1〜n4分别独立为2以上时，各A1〜A4中的任意一个相同或不同。 当锂电池包括电解质溶液时，可以提高锂电池的室温和高温寿命特性。
