TRIFLUOROMETHANESULFONAMIDE CAS 421-85-2

Trifluoromethanesulfonamide yog cov organic nruab nrab, uas tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm trifluoromethanesulfonyl chloride thiab ammonia roj. Trifluoromethanesulfonyl tuaj yeem siv los npaj LiTFSI. LiTFSI yog ib qho zoo heev organic electrolyte additive rau lithium roj teeb. Vim hais tias ntawm cov qauv tshuaj tshwj xeeb ntawm anion ib feem (CF3SO2) 2N-, LiTFSI muaj siab electrochemical stability thiab hluav taws xob conductivity; Piv nrog LiClO4 thiab LiPF6, LiTFSI li electrolyte additive tuaj yeem: 1) txhim kho SEI zaj duab xis ntawm qhov zoo thiab tsis zoo electrodes; 2) stabilize lub interface ntawm qhov zoo thiab tsis zoo electrodes; 3) inhibit gas tiam; 4) txhim kho lub voj voog kev ua haujlwm; 5) txhim kho qhov kub thiab txias stability; 6) Txhim kho kev cia khoom thiab lwm yam zoo.
