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). |
