Imikhiqizo

I-Lithium bis(trifluoromethanesulfonyl)imide, eyaziwa nangokuthi i-LiTFSI, iwusawoti we-lithium odlala indima ebalulekile ezimbonini ezahlukahlukene nasekusetshenzisweni kwesayensi.I-LiTFSI yakhiwe ngama-lithium cations (Li+) kanye ne-bis(trifluoromethanesulfonyl)imide anions (TFSI-).Kuyinhlanganisela ezinzile futhi engashi, okuyenza ibaluleke kakhulu emikhakheni eminingana.Okunye ukusetshenziswa okuyinhloko kwe-LiTFSI njenge-electrolyte kumabhethri e-lithium-ion.Isebenza njengendlela yokuqhuba eyenza ukugeleza kwe-lithium ion phakathi kwe-cathode ne-anode ngesikhathi sokushaja nokukhipha imijikelezo.I-LiTFSI ikhombisa ukuhambisana okuhle kakhulu nezinto ezahlukahlukene zama-electrode, ukuhanjiswa okuphezulu kwe-ionic, nokuzinza okuhle, okuyenza ibe ukukhetha okuthandwayo kwezinhlelo zebhethri ze-lithium-ion ezithuthukisiwe.Ukwengeza, i-LiTFSI isiza ukuthuthukisa ukuphepha, isikhathi sokuphila, kanye nokuminyana kwamandla kwalawa mabhethri, okunikela ekusetshenzisweni kwawo kabanzi ezintweni zikagesi eziphathwayo, ezimotweni zikagesi, nokugcinwa kwamandla. .Njenge-electrolyte, isiza ukuguqulwa okuphumelelayo kokukhanya kube ugesi, ngaleyo ndlela ithuthukise ukusebenza okuphelele kwalawa madivaysi e-photovoltaic.Ukuncibilika okuphezulu kwe-LiTFSI kuzincibilikisi ezisetshenziswa kakhulu kanye nekhono layo lokuhlinzeka ngokuqhutshwa kwe-ionic okuzinzile nokuqhubekayo kuyenza ibe yingxenye ebalulekile yokuthuthukisa ukudluliswa kwama-electron kanye nokunciphisa ukuhlanganisa kabusha kweshaji kumaseli elanga. ukusekela ukugcinwa okusheshayo nokukhululwa kwamandla kagesi.Ihlinzeka nge-conductivity ephezulu nokuzinza, okuvumela imijikelezo yokushaja ephumelelayo.Ama-Supercapacitor asebenzisa i-LiTFSI njenge-electrolyte athola ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu nokushajwa okusheshayo, njengezimoto zikagesi, izinhlelo zamandla avuselelekayo, nama-electronics abathengi.Ngaphezu kwalokho, i-LiTFSI isetshenziswa kuma-electrolyte e-polymer kumabhethri esimo esiqinile.Isiza ukuthuthukisa ukuqina kwemishini, ukuqhutshwa kwe-ionic, nokusebenza kwe-electrochemical kwalawa mabhethri, athathwa njengezinye izindlela ezithembisayo kunezinhlelo ezijwayelekile ezisekelwe ku-electrolyte oketshezi.I-LiTFSI inikela ekuthuthukisweni kwamabhethri esifunda esiqinile aphephile nanamandla amakhulu, asetshenziswa ezintweni zikagesi eziphathwayo, ezimotweni zikagesi, kanye nesitoreji segridi.Kufanele futhi ukubalula ukuthi i-LiTFSI ithola ukusetshenziswa kwezinye izindawo, okuhlanganisa ama-electrolyte azinzile ngamakhemikhali nangokwe-thermal. , catalysis, and solvents for chemical reactions.Sekukonke, i-LiTFSI iyinhlanganisela ehlukahlukene edlala indima ebalulekile ekugcinweni kwamandla nasezinhlelweni zokuguqula, ikakhulukazi kumabhethri e-lithium-ion, amaseli elanga, nama-supercapacitor.Izakhiwo zayo eziyingqayizivele, njengokuncibilika okuphezulu, ukuzinza, kanye nokusebenza kahle, kuyenza ibe yingxenye ebalulekile ekuthuthukisweni kwezimboni nobuchwepheshe obuhlukahlukene obuya ekusaseni elizinzile nelisebenza ngempumelelo.
