I-Fluoroethylene carbonate ineenzuzo ezininzi kunezongezo eziqhelekileyo ze-electrolyte.Okokuqala, yenza umaleko onqabileyo okhuselayo, owaziwa ngokuba yi-electrolyte interface eqinileyo (SEI), kumphezulu wesinyithi we-lithium.Olu luhlu lwe-SEI lunokuthintela uqhagamshelwano oluthe ngqo phakathi kwe-lithium electrode kunye ne-electrolyte, ngokufanelekileyo ukunciphisa umngcipheko wokuphendula okungalunganga kunye nokuqinisekisa ubomi obude bebhetri.

Ukongeza, i-FEC inceda ukuphucula ukuzinza kwe-electrochemical jikelele yebhetri.Iimpawu zayo ezigqwesileyo zeekhemikhali zenza ukuba kuqulunqwe uluhlu oluzinzile kunye noluqinileyo lwe-SEI, ngaloo ndlela lunciphisa ukuthotywa kwe-lithium electrode ngexesha lokuhlawula kunye nokukhupha imijikelezo.Ngenxa yoko, iibhetri ziyakwazi ukumelana nombane ophezulu kwaye zibonise ukusebenza okuphuculweyo kokuhamba ngebhayisikile, okukhokelela kugcino lwamandla kunye nobomi bebhetri obude.

Ukongezelela, ukongezwa kwe-fluoroethylene carbonate kwi-electrolyte formulation kunokuphucula kakhulu ukhuseleko lweebhetri ze-lithium-ion.Ngokulungisa i-interface ye-electrolyte-electrode, icinezela ukubunjwa kwee-dendrites, eziyizakhiwo ezifana nenaliti ezinokukhokelela kwiisekethe ezimfutshane zangaphakathi kwaye ezinokuthi zikhokelela ekubalekeni kwe-thermal.Oku kwenza iibhetri zithembeke ngakumbi kwaye zinciphisa umngcipheko weziganeko ezinobungozi, ukuqinisekisa uxolo lwengqondo kubavelisi kunye nabasebenzisi bokugqibela.

Isishwankathelo, i-chemistry yethu ye-innovative, i-fluoroethylene carbonate (i-CAS: 114435-02-8), inguqu yomdlalo we-Li-ion yokongeza ibhetri.Ngokukwazi kwayo ukuzinzisa ujongano lwe-electrode-electrode, ukuphucula uzinzo lwe-electrochemical, kunye nokuphucula ukhuseleko lwebhetri, ngokuqinisekileyo kuya kubumba ikamva letekhnoloji yokugcina amandla.Siqinisekile ukuba le khompawundi ikhethekileyo iya kudibana kwaye igqithise okulindelweyo kushishino, kwaye sijonge phambili ekusebenzeni nawe ukudala ikamva lamandla elizinzileyo nelisebenzayo.
