Bistrifluoromethanesulfonimide lithiamu mchere, womwe umadziwika kuti LiTFSI, ndiwosinthasintha komanso wogwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, kuphatikiza electrochemistry, kusungirako mphamvu, komanso kaphatikizidwe ka organic.Ndi mchere wopangidwa ndi kuphatikiza kwa lithiamu cations (Li +) ndi bistrifluoromethanesulfonimide anions (TFSI-) .Imodzi mwa ntchito zazikulu za LiTFSI zili mu mabatire a lithiamu-ion.LiTFSI imagwiritsidwa ntchito ngati chowonjezera cha electrolyte kupititsa patsogolo magwiridwe antchito ndi chitetezo cha mabatire a lithiamu-ion.TFSI-anion imawonetsa kukhazikika kwa electrochemical, kupangitsa kuyenda kosasunthika komanso kuwongolera bwino kwa batire.Kukhalapo kwa LiTFSI mu electrolyte kumathandizira kupondereza machitidwe osayenera ndikuwonjezera ma ionic conductivity mkati mwa batire.Kuonjezera apo, LiTFSI imakhala ndi kusungunuka kochepa komanso kutentha kwakukulu kwa kutentha, kuchepetsa chiopsezo cha kuwonongeka kwa kutentha komanso kumapangitsa kuti batire ikhale yotetezeka.Ma ionic conductivity ake apamwamba komanso magwero abwino kwambiri amamupangitsa kukhala chisankho chabwino pamapulogalamuwa.Ma electrolyte opangidwa ndi LiTFSI apezeka kuti ali ndi kukhazikika kwabwino, mazenera ambiri a electrochemical, komanso kukhazikika kwapang'onopang'ono, zomwe zimapangitsa kuti chipangizocho chizigwira bwino ntchito. M'munda wa organic synthesis, LiTFSI imapeza ntchito ngati chothandizira cha Lewis acid komanso chothandizira kutumiza magawo.Monga Lewis acid, LiTFSI imatha kuyambitsa magulu osiyanasiyana ogwira ntchito ndikufulumizitsa zomwe mukufuna.Zakhala zikugwiritsidwa ntchito pakusintha kosiyanasiyana, kuphatikiza esterification, acetalization, ndi machitidwe a CC bond.Kuphatikiza apo, monga chothandizira kusamutsa gawo, LiTFSI imatha kuthandizira kuwongolera zochitika pakati pa magawo osasinthika ndikulimbikitsa kusamutsa ma reactants kudutsa magawo, kupititsa patsogolo magwiridwe antchito.Amagwiritsidwa ntchito ngati gawo popanga ma electrolyte a polima ndi ma electrolyte olimba a mabatire.Kuphatikizika kwake kumapangitsa kuti ma ion conductivity akhazikike komanso kukhazikika kwa zidazi, kukulitsa magwiridwe antchito awo onse ndi chitetezo.Ndikofunikira kuzindikira kuti LiTFSI iyenera kusamalidwa mosamala, chifukwa ndi gulu la hygroscopic ndipo liyenera kusungidwa pamalo owuma.Imakhudzidwanso ndi chinyezi ndi mpweya, ndipo kusamala kuyenera kuchitidwa kuti kuchepetsa kukhudzana ndi izi.Mwachidule, bistrifluoromethanesulfonimide lithium salt (LiTFSI) ndi mankhwala osakanikirana omwe ali ndi ntchito zambiri.Kuchokera pakugwiritsa ntchito mabatire a lithiamu-ion ndi ma supercapacitor mpaka gawo lake monga chothandizira pakuphatikizika kwachilengedwe komanso ngati gawo la ma electrolyte a polima, LiTFSI imatenga gawo lofunikira pazantchito zosiyanasiyana zasayansi ndiukadaulo.Njira zoyendetsera bwino ndi zosungira ziyenera kutsatiridwa kuti zitsimikizire kukhazikika kwake komanso kugwira ntchito.
