제목 Multi-functional Zwitterionic compounds as additives for electrolyte of lithium secondary battery
초록 Zwitterionic compounds containing ester and sulfonyl group have been synthesized and the physical and electrochemical characteristics have been investigated. FT-IR study clearly demonstrates the interaction of Li+ with both of their functional groups. The cell capacity with the addition of either MePyrS or MePipS as an additive dropped , whereas such a sharp decrease of the performance at higher C-rate was not observed when these none-ester-ZWs were replaced by ester-ZWs, implying the positive role of the ester functional group. Most importantly, the pyrrolydinium-based ZWs showed very good cycle perfomance (nealy 90% capacity for 100 cycles).
