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.

Ntxiv 172g ntawm 98% CF3SO2Cl (1mol) thiab 500mL ntawm anhydrous acetonitrile tom qab kev kho dej nyob rau hauv lub kaw reactor nrog ib tug pas ntsuas kub, ib tug stirrer, thiab nitrogen thiab oxygen tshem tawm.Cov roj ammonia lossis cov nqi sib thooj ntawm cov khoom siv ammonia qhuav yog maj mam nce mus rau chav sov hauv qab nplawm, thiab cov tshuaj tiv thaiv raug txiav tawm tom qab 3 teev cov tshuaj tiv thaiv.Cov khoom los ntawm ammonium chloride nyob rau hauv cov tshuaj tiv thaiv raug tshem tawm los ntawm kev pom, cov kuab tshuaj nyob rau hauv lub filtrate yog distilled tawm nyob rau hauv lub siab txo, thiab qhuav nyob rau hauv txo siab ntawm 50 ° C kom tau ib tug dawb wafer crude trifluoromethanesulfonamide nrog ib tug yield tsis tsawg tshaj li. 96%.
