Fluoroethylene carbonate nwere ọtụtụ uru karịa ihe mgbakwunye electrolyte.Nke mbụ, ọ na-etolite oyi akwa nchebe dị gịrịgịrị, nke a makwaara dị ka interface electrolyte siri ike (SEI), na elu igwe lithium.Ihe oyi akwa SEI a nwere ike igbochi kọntaktị kpọmkwem n'etiti electrode lithium na electrolyte, na-ebelata ihe ize ndụ nke mmeghachi omume ọjọọ na-eme ka ndụ batrị dịkwuo ogologo.

Na mgbakwunye, FEC na-enyere aka melite nkwụsi ike electrochemical zuru oke nke batrị ahụ.Ngwongwo kemịkalụ ya mara mma na-enyere aka guzobe oyi akwa SEI kwụsiri ike ma sie ike, si otú a na-ebelata mmebi nke electrodes lithium n'oge chaja na mwepu.N'ihi ya, batrị nwere ike iguzogide voltaji dị elu ma gosipụta arụmọrụ ịgba ígwè ka mma, na-eduga na nchekwa nchekwa ike na ogologo ndụ batrị.

Na mgbakwunye, mgbakwunye nke fluoroethylene carbonate na usoro electrolyte nwere ike imeziwanye nchekwa nke batrị lithium-ion nke ọma.Site n'ịkwalite interface electrolyte-electrode interface, ọ na-egbochi nhazi nke dendrites, nke bụ ihe dị ka agịga nke nwere ike iduga n'ime obere sekit dị n'ime ma nwee ike iduga na-agbapụ ọkụ.Nke a na-eme ka batrị bụrụ ndị a pụrụ ịdabere na ya ma na-ebelata ihe ize ndụ nke ihe ize ndụ, na-eme ka obi dị jụụ maka ndị nrụpụta na ndị ọrụ njedebe.

Na nchịkọta, kemistri ọhụrụ anyị, fluoroethylene carbonate (CAS: 114435-02-8), bụ ihe mgbakwunye batrị Li-ion na-agbanwe egwuregwu.Site n'ikike ya ime ka interface electrolyte-electrode kwụsie ike, melite nkwụsi ike nke electrochemical, na ịkwalite nchekwa batrị, ọ ga-abụ na ọ ga-akpụzi ọdịnihu nke teknụzụ nchekwa ike.Anyị nwere obi ike na nke a pụrụ iche onyinye ga-ezute na gafere ụlọ ọrụ na-atụ anya, na anyị na-atụ anya na-arụ ọrụ na gị ka ike a ọzọ adigide na oru oma ume n'ọdịnihu.
