Vinyl Ethylene Carbonate (VEC) (CAS: 4427-96-7) hutumika kama kiongeza tendaji sana cha kutengeneza filamu katika betri za upili za lithiamu;kuajiriwa katika usanisi wa polima zinazofanya kazi.VEC ina kiwango cha juu cha dielectric, kiwango cha juu cha mchemko na hatua ya flash, ambayo ni ya manufaa kuboresha utendaji wa usalama wa betri ya ioni ya lithiamu.VEC huanza kuoza kwa 1.35V, na inaweza kuunda filamu thabiti na mnene ya SEI kwenye grafiti ya flake, ambayo inazuia kwa ufanisi PC na ioni ya lithiamu iliyoyeyushwa kutoka kwa kupachika kwenye safu ya grafiti, na kuzuia mtengano wa elektroliti kwa kiwango cha chini, na hivyo kuboresha. malipo na ufanisi wa kutokwa na sifa za baiskeli ya betri ya ioni ya lithiamu.Sifa za kemikali ni thabiti.Wakati kiasi fulani cha VEC kinaongezwa kwa electrolyte kwa joto linalofaa, utendaji wa mzunguko wa chuma cha cathode unaweza kuboreshwa kwa kiasi kikubwa.Baada ya mizunguko kadhaa ya kutokwa kwa malipo, uwezo wa kutokwa uliobaki unaweza kuongezeka kutoka 68.8% hadi 84.8%.
