Vinyl Ethylene Carbonate (VEC) CAS 4427-96-7 4-Vinyl-1,3-dioxolan-2-one Purity>99.5% (GC)

Vinyl Ethylene Carbonate (VEC) (CAS: 4427-96-7) imagwiritsidwa ntchito ngati chowonjezera chowonjezera chopanga mafilimu mu mabatire achiwiri a lithiamu;amagwiritsidwa ntchito popanga ma polima ogwira ntchito.VEC ili ndi ma dielectric okhazikika, malo otentha kwambiri ndi mfundo yowunikira, zomwe zimapindulitsa kupititsa patsogolo chitetezo cha batri ya lithiamu ion.VEC amayamba kuwola pa 1.35V, ndipo akhoza kupanga khola ndi wandiweyani SEI filimu pa flake graphite, amene mogwira kuteteza PC ndi kusungunuka lifiyamu ion ku co-embedding mu graphite wosanjikiza, ndipo linalake ndipo tikulephera kuwonongeka kwa electrolyte kuti osachepera, motero kuwongolera. Kuwongolera ndi kutulutsa mphamvu komanso kuyendetsa njinga kwa batri ya lithiamu ion.Mankhwalawa ndi okhazikika.Pamene kuchuluka kwa VEC kuwonjezeredwa ku electrolyte pa kutentha koyenera, ntchito ya cyclic ya cathode metal imatha kusintha kwambiri.Pambuyo pozungulira kangapo kotulutsa, mphamvu yotayira yosungidwa imatha kuwonjezeka kuchokera pa 68.8% mpaka 84.8%.
