I-Bistrifluoromethanesulfonimide ityuwa ye-lithium, eyaziwa ngokuba yi-LiTFSI, iyikhompawundi eguquguqukayo kakhulu kwaye isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo, kubandakanya i-electrochemistry, ukugcinwa kwamandla, kunye ne-organic synthesis.Ityuwa eyenziwe ngokudibanisa i-lithium cations (Li +) kunye ne-bistrifluoromethanesulfonimide anions (TFSI-) .Enye yezicelo eziphambili ze-LiTFSI kwiibhetri ze-lithium-ion.I-LiTFSI isetyenziswa njengesongezo se-electrolyte ukuphucula ukusebenza kunye nokhuseleko lweebhetri ze-lithium-ion.I-TFSI-anion ibonisa uzinzo olugqwesileyo lwe-electrochemical, ivumela ukukhwela ibhayisekile okuzinzileyo kunye nokuphucula ukusebenza kakuhle kwebhetri iyonke.Ubukho be-LiTFSI kwi-electrolyte kunceda ukucinezela ukuphendula okungafunekiyo kunye nokuphucula ukuhanjiswa kwe-ionic ngokubanzi ngaphakathi kwebhetri.Ukongezelela, i-LiTFSI ine-volatility ephantsi kunye nokuzinza okuphezulu kwe-thermal, ukunciphisa umngcipheko wokuchithwa kwe-thermal kunye nesiphumo sokusebenza kwebhetri ekhuselekileyo.I-ionic conductivity ephezulu kunye neempawu ezibalaseleyo zokusombulula ziyenza ibe lolona khetho lufanelekileyo kwezi zicelo.I-electrolyte esekwe kwi-LiTFSI ifunyenwe inozinzo oluhle, iifestile ezibanzi ze-electrochemical, kunye nokuzinza okuphezulu kwebhayisikile, okukhokelela ekusebenzeni okuphuculweyo kwesixhobo. Kwintsimi ye-organic synthesis, i-LiTFSI ifumana isicelo njenge-Lewis acid catalyst kunye ne-phase-transfer catalyst.Njengeasidi ye-Lewis, i-LiTFSI inokuvula amaqela ahlukeneyo asebenzayo kwaye ikhawulezise ukusabela okufunekayo.Isetyenziswe kuluhlu lweenguqu, kubandakanywa i-esterification, i-acetalization, kunye neempendulo ze-CC bond formation.Ngaphezu koko, njenge-catalyst ye-phase-transfer, i-LiTFSI inokunceda ukuququzelela ukusabela phakathi kwezigaba ezingenakulinganiswa kunye nokukhuthaza ukudluliselwa kwezinto ezixutywayo kuzo zonke izigaba, ukuphucula ukusebenza kakuhle kokusabela.Ngaphezu koko, i-LiTFSI ibandakanyeka kwiindawo ezahlukeneyo zophando, ezifana nesayensi ye-polymer kunye nekhemistri yezixhobo.Isetyenziswa njengenxalenye ekudityanisweni kwee-electrolyte ze-polymer kunye ne-electrolyte eqinile yesimo seebhetri.Ukufakwa kwayo kuphucula i-ion conductivity kunye nokuzinza kwezi zinto, ukuphucula ukusebenza kwazo zonke kunye nokhuseleko.Kubalulekile ukuba uqaphele ukuba i-LiTFSI kufuneka iphathwe ngokunyamekela, njengoko i-hygroscopic compound kwaye kufuneka igcinwe kwindawo eyomileyo.Kwakhona kuvakalelwa kumswakama kunye nomoya, kwaye kufuneka kuthathwe amanyathelo okukhusela ukunciphisa ukuvezwa kwezi meko.Ngokufutshane, i-bistrifluoromethanesulfonimide ityuwa ye-lithium (i-LiTFSI) i-compound eguquguqukayo kunye noluhlu olubanzi lwezicelo.Ukusuka kusetyenziso lwayo kwiibhetri ze-lithium-ion kunye nee-supercapacitors ukuya kwindima yayo njenge-catalyst kwi-organic synthesis kunye nenxalenye ye-polymer electrolytes, i-LiTFSI idlala indima ebalulekileyo kwiinzame ezahlukeneyo zesayensi kunye nezobuchwepheshe.Ukuphathwa ngokufanelekileyo kunye neendlela zokugcina kufuneka zilandelwe ukuqinisekisa ukuzinza nokusebenza kwayo.
