Chinese patent application publication No. CN104659414B discloses a lithium secondary battery and a nonaqueous electrolytic solution used therein, which describes that lithium difluorophosphate and a cyclic siloxane compound are used in combination, and have excellent low-temperature discharge performance and cycle performance. However, these additives themselves generally have problems of difficulty in achieving both high and low temperature performance, short high temperature cycle life, and poor safety performance, for example, a phenomenon of high temperature gas generation in lithium bis (oxalato) borate, a phenomenon of corrosion of aluminum foil in LiFSI, and a phenomenon of low temperature lithium precipitation in lithium difluorophosphate. Therefore, it is urgently needed to develop a new additive which can combine high and low temperature and cycle performance.
