China yabwino Fluoroethylene carbonate/FEC CAS:114435-02-8

Kufotokozera Kwachidule:

Fluoroethylene carbonate (FEC) ndi organic pawiri kuti makamaka ntchito monga electrolyte zowonjezera kwa lithiamu-ion mabatire.Ethylene carbonate yochokera ku vinyl fluoride idayambitsidwa.Njirayi imapanga chophatikiza chapadera chokhala ndi zinthu zochititsa chidwi zomwe zimatha kusintha kwambiri magwiridwe antchito komanso moyo wa mabatire omwe amatha kuchangidwa.FEC ndi gawo lofunikira kuti likhazikitse mawonekedwe pakati pa Li metal anode ndi electrolyte, zomwe zimapangitsa kuti pakhale ntchito yotetezeka komanso yogwira ntchito.

Fluoroethylene carbonate ili ndi zabwino zambiri kuposa zowonjezera zowonjezera ma electrolyte.Choyamba, amapanga wosanjikiza woonda zoteteza, wotchedwanso olimba electrolyte mawonekedwe (SEI), pa lithiamu zitsulo pamwamba.Wosanjikiza wa SEI uyu angalepheretse kulumikizana kwachindunji pakati pa electrode ya lithiamu ndi electrolyte, kuchepetsa chiopsezo cha zovuta zoyipa ndikuwonetsetsa kuti batire italikirapo.

Kuphatikiza apo, FEC imathandizira kukonza kukhazikika kwa electrochemical batire.Mankhwala ake abwino kwambiri amathandizira kupanga gawo lokhazikika komanso lolimba la SEI, potero amachepetsa kuwonongeka kwa ma electrode a lithiamu panthawi yamalipiro ndi kutulutsa.Zotsatira zake, mabatire amatha kupirira ma voltages okwera ndikuwonetsa kuyendetsa bwino kwa njinga, zomwe zimapangitsa kuti mphamvu zisungidwe bwino komanso moyo wautali wa batri.

Kuphatikiza apo, kuwonjezera kwa fluoroethylene carbonate ku mapangidwe a electrolyte kumatha kusintha kwambiri chitetezo cha mabatire a lithiamu-ion.Mwa kukhathamiritsa mawonekedwe a electrolyte-electrode, imalepheretsa mapangidwe a dendrites, omwe ali ngati singano zomwe zingayambitse mabwalo amkati amkati ndikutha kuthamangitsa kutentha.Izi zimapangitsa mabatire kukhala odalirika komanso kuchepetsa chiopsezo cha zochitika zoopsa, kuonetsetsa mtendere wamaganizo kwa opanga ndi ogwiritsa ntchito mapeto.

Mwachidule, chemistry yathu yatsopano, fluoroethylene carbonate (CAS: 114435-02-8), ndiyowonjezera pamasewera a Li-ion batire.Ndi kuthekera kwake kukhazikika mawonekedwe a electrolyte-electrode, kukonza kukhazikika kwa electrochemical, ndikuwonjezera chitetezo cha batri, ndikutsimikiza tsogolo laukadaulo wosungira mphamvu.Tili ndi chidaliro kuti gulu lapaderali lidzakwaniritsa ndikupitilira zomwe makampani amayembekeza, ndipo tikuyembekeza kugwira ntchito nanu kuti mupange tsogolo lokhazikika komanso logwira ntchito lamphamvu.
