TRIFLUOROMETHANESULFONAMIDE Ndi CAS 421-85-2
Trifluoromethanesulfonamide ndi organic wapakatikati, amene akhoza kukonzekera ndi zimene trifluoromethanesulfonyl kolorayidi ndi ammonia mpweya.Trifluoromethanesulfonyl itha kugwiritsidwa ntchito pokonzekera LiTFSI.LiTFSI ndi chowonjezera chabwino kwambiri cha organic electrolyte pamabatire a lithiamu.Chifukwa cha mapangidwe apadera a mankhwala a anion part (CF3SO2) 2N-, LiTFSI ili ndi kukhazikika kwapamwamba kwa electrochemical ndi kusinthika kwamagetsi;Poyerekeza ndi LiClO4 ndi LiPF6, LiTFSI monga chowonjezera cha electrolyte chingathe: 1) kukonza filimu ya SEI ya ma electrode abwino ndi oipa;2) kukhazikika kwa mawonekedwe a maelekitirodi abwino ndi oipa;3) kuletsa m'badwo wa gasi;4) kusintha magwiridwe antchito;5) kusintha kutentha kwapamwamba;6) Sinthani magwiridwe antchito ndi zabwino zina.
