I-China engcono kakhulu ye-Fluoroethylene carbonate/FEC CAS:114435-02-8

Incazelo emfushane:

I-Fluoroethylene carbonate (FEC) iyinhlanganisela yemvelo esetshenziswa kakhulu njengesengezo se-electrolyte kumabhethri e-lithium-ion.Kwethulwa i-ethylene carbonate etholakala ku-vinyl fluoride.Inqubo ikhiqiza isakhi esiyingqayizivele esinezici eziphawulekayo ezingathuthukisa kakhulu ukusebenza nempilo yamabhethri aphinde ashajwe.I-FEC iyingxenye ebalulekile yokusimamisa ukuxhumana phakathi kwe-Li metal anode ne-electrolyte, okuholela ekusebenzeni okuphephile nokusebenza kahle.

I-fluoroethylene carbonate inezinzuzo eziningi ngaphezu kwezithasiselo ezivamile ze-electrolyte.Okokuqala, yakha ungqimba oluncane oluvikelayo, olwaziwa nangokuthi i-solid electrolyte interface (SEI), endaweni yensimbi ye-lithium.Lesi sendlalelo se-SEI singavimbela ukuthintana okuqondile phakathi kwe-lithium electrode kanye ne-electrolyte, kunciphise ngokuphumelelayo ingozi yokusabela okungathandeki ohlangothini nokuqinisekisa ukuphila kwebhethri ende.

Ngaphezu kwalokho, i-FEC isiza ukuthuthukisa ukuzinza okuphelele kwe-electrochemical yebhethri.Izakhiwo zayo zamakhemikhali ezinhle kakhulu zivumela ukwakheka kongqimba oluzinzile noluqinile lwe-SEI, ngaleyo ndlela kunciphisa ukuwohloka kwama-electrode e-lithium ngesikhathi sokushaja nokukhipha imijikelezo.Ngenxa yalokho, amabhethri angakwazi ukumelana nama-voltage aphezulu futhi abonise ukusebenza kwamabhayisikili okuthuthukisiwe, okuholela ekugcinweni okuthuthukisiwe kwamandla nempilo yebhethri ende.

Ngaphezu kwalokho, ukungezwa kwe-fluoroethylene carbonate ekwakhiweni kwe-electrolyte kungathuthukisa kakhulu ukuphepha kwamabhethri e-lithium-ion.Ngokulungiselela isixhumi esibonakalayo se-electrode-electrode, icindezela ukwakheka kwama-dendrite, okuyizakhiwo ezifana nenaliti ezingaholela kumasekhethi amafushane angaphakathi futhi okungenzeka ziholele ekubalekeni okushisayo.Lokhu kwenza amabhethri athembeke kakhulu futhi kunciphisa ingcuphe yezehlakalo eziyingozi, okuqinisekisa ukuthula kwengqondo kubakhiqizi nabasebenzisi bokugcina.

Kafushane, i-chemistry yethu emisha, i-fluoroethylene carbonate (CAS: 114435-02-8), iyisengezo sebhethri ye-Li-ion esishintsha umdlalo.Ngamandla ayo okuzinzisa isixhumi esibonakalayo se-electrode, ukuthuthukisa ukuzinza kwe-electrochemical, nokuthuthukisa ukuphepha kwebhethri, iqinisekile ukuthi izobumba ikusasa lobuchwepheshe bokugcina amandla.Siyaqiniseka ukuthi le nhlanganisela eyingqayizivele izohlangabezana futhi yeqe okulindelwe yimboni, futhi sibheke ngabomvu ukusebenzisana nawe ukuze sakhe ikusasa lamandla elizinzile nelisebenza ngempumelelo.
