I-Bistrifluoromethanesulfonimide lithium salt, evame ukubizwa ngokuthi i-LiTFSI, iyinhlanganisela eguquguqukayo futhi esetshenziswa kabanzi emikhakheni eyahlukene, okuhlanganisa i-electrochemistry, ukugcinwa kwamandla, kanye nokuhlanganiswa kwezinto eziphilayo.Iwusawoti owenziwe inhlanganisela ye-lithium cations (Li+) kanye ne-bistrifluoromethanesulfonimide anions (TFSI-).Olunye lwezinhlelo zokusebenza eziyinhloko ze-LiTFSI kusemabhethri e-lithium-ion.I-LiTFSI isetshenziswa njengesengezo se-electrolyte ukuthuthukisa ukusebenza nokuphepha kwamabhethri e-lithium-ion.I-TFSI-anion ibonisa ukuzinza okuhle kakhulu kwe-electrochemical, ivumela ukuhamba kwamabhayisikili okuzinzile kanye nokusebenza kahle kwebhethri okuphelele.Ukuba khona kwe-LiTFSI ku-electrolyte kusiza ukucindezela ukusabela okungathandeki futhi kuthuthukise ukuqhutshwa kwe-ionic okuphelele ngaphakathi kwebhethri.Ukwengeza, i-LiTFSI inokuguquguquka okuphansi kanye nokuzinza okuphezulu kokushisa, ukunciphisa ingozi yokubola okushisayo futhi kubangele ukusebenza kwebhethri okuphephile.I-ionic conductivity yayo ephezulu kanye nezakhiwo ezinhle kakhulu zokuxazulula ikwenza kube ukukhetha okuhle kulezi zinhlelo zokusebenza.Ama-electrolyte asekelwe ku-LiTFSI atholakale enokuqina okuhle, amafasitela abanzi kagesi kagesi, kanye nokuzinza okuphezulu kwamabhayisikili, okuholela ekusebenzeni okuthuthukisiwe kwedivayisi.Emkhakheni we-organic synthesis, i-LiTFSI ithola ukusetshenziswa njenge-Lewis acid catalyst kanye ne-phase-transfer catalyst.Njenge-Lewis acid, i-LiTFSI ingenza kusebenze amaqembu ahlukahlukene asebenzayo futhi isheshise ukusabela okufunayo.Isetshenziswe ezinhlobonhlobo zezinguquko, okuhlanganisa i-esterification, i-acetalization, kanye nokusabela kokwakheka kwebhondi ye-CC.Ngaphezu kwalokho, njenge-catalyst yokudluliselwa kwesigaba, i-LiTFSI ingasiza ekwenzeni ukusabela phakathi kwezigaba ezingahlangani futhi ikhuthaze ukudluliswa kwama-reactants kuzo zonke izigaba, ithuthukise ukusebenza kahle kokusabela.Ngaphezu kwalokho, i-LiTFSI ihileleke ezindaweni ezihlukahlukene zocwaningo, njengesayensi ye-polymer kanye namakhemikhali wezinto ezibonakalayo.Isetshenziswa njengengxenye ekuhlanganisweni kwama-electrolyte e-polymer kanye nama-electrolyte esimo esiqinile samabhethri.Ukufakwa kwayo kuthuthukisa i-ion conductivity nokuzinza kwalezi zinto, kuthuthukisa ukusebenza kwazo zonke kanye nokuphepha.Kubalulekile ukuqaphela ukuthi i-LiTFSI kufanele iphathwe ngokucophelela, njengoba iyinhlanganisela ye-hygroscopic futhi kufanele igcinwe endaweni eyomile.Futhi iyazwela kumswakama nomoya, futhi kufanele kuthathwe izinyathelo zokuqapha ukuze kuncishiswe ukuchayeka kulezi zimo.Kafushane, i-bistrifluoromethanesulfonimide lithium salt (LiTFSI) iyinhlanganisela ehlukahlukene enezinhlelo eziningi zokusebenza.Kusukela ekusetshenzisweni kwayo kumabhethri e-lithium-ion nama-supercapacitor kuya endimeni yawo njengesisusa ekuhlanganiseni izinto eziphilayo nanjengengxenye yama-polymer electrolyte, i-LiTFSI idlala indima ebalulekile emizamweni eyahlukene yesayensi nezobuchwepheshe.Izinqubo ezifanele zokuphatha nokugcina kufanele zilandelwe ukuze kuqinisekiswe ukuzinza nokusebenza kwayo.
