Vinyl Ethylene Carbonate (VEC) (CAS: 4427-96-7) digunakake minangka aditif pembentuk film sing reaktif banget ing baterei sekunder lithium;digunakake ing sintesis polimer fungsional.VEC nduweni konstanta dielektrik dhuwur, titik didih dhuwur lan titik lampu kilat, sing migunani kanggo ningkatake kinerja safety baterei lithium ion.VEC wiwit decompose ing 1.35V, lan bisa mbentuk film SEI stabil lan kandhel ing flake grafit, kang èfèktif ngalangi PC lan ion lithium solvated saka co-embedding menyang lapisan grafit, lan nyegah bosok saka elektrolit kanggo minimal, saéngga nambah. efisiensi pangisian daya lan discharge lan karakteristik siklus baterei lithium ion.Sifat kimia sing stabil.Nalika jumlah tartamtu saka VEC ditambahake menyang elektrolit ing suhu cocok, kinerja cyclic saka logam katoda bisa Ngartekno apik.Sawise sawetara siklus ngisi-discharge, kapasitas discharge sing ditahan bisa ditambah saka 68,8% dadi 84,8%.
