TRIFLUOROMETHANESULFONAMIDE Ka CAS 421-85-2
Trifluoromethanesulfonamide ke organic intermediate, e ka lokisoang ke karabelo ea trifluoromethanesulfonyl chloride le khase ea ammonia.Trifluoromethanesulfonyl e ka sebelisoa ho lokisa LiTFSI.LiTFSI ke tlatsetso e ntle ea organic electrolyte bakeng sa libeteri tsa lithium.Ka lebaka la sebopeho se khethehileng sa lik'hemik'hale sa karolo ea anion (CF3SO2) 2N-, LiTFSI e na le botsitso bo phahameng ba electrochemical le conductivity ea motlakase;Ha ho bapisoa le LiClO4 le LiPF6, LiTFSI e le tlatsetso ea electrolyte e ka: 1) ho ntlafatsa filimi ea SEI ea li-electrode tse ntle le tse mpe;2) tsitsisa sebopeho sa li-electrode tse ntle le tse mpe;3) thibela tlhahiso ea khase;4) ho ntlafatsa ts'ebetso ea potoloho;5) ntlafatsa botsitso ba mocheso o phahameng;6) Ntlafatsa ts'ebetso ea polokelo le melemo e meng.
