Bistrifluoromethanesulfonimide lithium nnu, nke a na-akpọkarị LiTFSI, bụ ngwakọta nke ukwuu na nke a na-ejikarị eme ihe na mpaghara dị iche iche, gụnyere electrochemistry, nchekwa ike, na njikọ organic.Ọ bụ nnu nke a na-emepụta site na nchikota nke lithium cations (Li +) na bistrifluoromethanesulfonimide anions (TFSI-) . Otu n'ime ngwa ngwa nke LiTFSI dị na batrị lithium-ion.A na-eji LiTFSI dị ka mgbakwunye electrolyte iji kwalite arụmọrụ na nchekwa nke batrị lithium-ion.TFSI-anion na-egosipụta ezigbo nkwụsi ike elektrọnịkị, na-eme ka ịgba ígwè kwụsie ike ma kwalite arụmọrụ batrị n'ozuzu ya.Ọnụnọ nke LiTFSI na electrolyte na-enyere aka ịkwụsị mmeghachi omume akụkụ na-adịghị mma ma welie arụmọrụ ionic n'ime batrị ahụ.Na mgbakwunye, LiTFSI nwere mgbanwe dị ala yana nkwụsi ike dị elu, na-ebelata ihe ize ndụ nke ire ere ọkụ ma na-ebute ọrụ batrị dị mma.Nrụ ọrụ ionic dị elu ya na ihe ndozi dị mma na-eme ka ọ bụrụ ezigbo nhọrọ maka ngwa ndị a.Achọpụtala electrolytes dabeere na LiTFSI nwere ezigbo nkwụsi ike, windo electrochemical sara mbara, na nkwụsi ike nke ịgba ígwè, na-eduga n'ịrụ ọrụ ngwaọrụ ka mma. N'ihe gbasara njikọ organic, LiTFSI na-achọta ngwa dị ka Lewis acid catalyst na onye na-ebufe oge.Dị ka Lewis acid, LiTFSI nwere ike ịgbalite otu dị iche iche na-arụ ọrụ ma mee ka mmeghachi omume dị ngwa ngwa.Ejila ya n'ọtụtụ mgbanwe dị iche iche, gụnyere esterification, acetalization, na mmeghachi omume nhazi njikọ CC.Ọzọkwa, dị ka a na-adọ-enyefe catalyst, LiTFSI nwere ike inyere ikwado mmeghachi omume n'etiti immiscible n'ụzọ na-akwalite nyefe nke reactants gafee usoro, na-eme ka mmeghachi omume efficiency. Ọzọkwa, LiTFSI na-etinye aka na dị iche iche nnyocha ebe, dị ka polymer sayensị na ihe kemịkalụ.A na-eji ya dị ka akụkụ na njikọ nke polymer electrolytes na steeti electrolytes siri ike maka batrị.Ntinye ya na-eme ka ion conductivity na nkwụsi ike nke ihe ndị a dịkwuo mma, na-eme ka arụmọrụ ha na nchekwa ha dịkwuo mma. Ọ dị mkpa iburu n'obi na LiTFSI kwesịrị iji nlezianya mee ihe, ebe ọ bụ ihe hygroscopic na-echekwa ya na ebe akọrọ.Ọ na-enwekwa mmetụta maka mmiri na ikuku, na a ga-akpachara anya iji belata ikpughe na ọnọdụ ndị a.Na nchịkọta, bistrifluoromethanesulfonimide lithium salt (LiTFSI) bụ ihe dị iche iche nwere ọtụtụ ngwa.Site na ojiji ya na batrị lithium-ion na ndị na-ebu ibu ruo ọrụ ya dị ka ihe na-akpali akpali na njikọ organic yana dị ka akụkụ na polymer electrolytes, LiTFSI na-arụ ọrụ dị mkpa na mbọ sayensị na teknụzụ dị iche iche.Ekwesịrị ịgbaso usoro njikwa na nchekwa nke ọma iji hụ na nkwụsi ike na ịdị irè ya.
