Tuam Tshoj zoo tshaj plaws Fluoroethylene carbonate / FEC CAS: 114435-02-8

Lus piav qhia luv luv:

Fluoroethylene carbonate (FEC) yog ib qho organic compound uas yog siv los ua cov khoom siv hluav taws xob ntxiv rau cov roj teeb lithium-ion.Ethylene carbonate muab tau los ntawm vinyl fluoride tau qhia.Cov txheej txheem tsim cov khoom sib xyaw tshwj xeeb nrog cov khoom zoo kawg nkaus uas tuaj yeem txhim kho kev ua tau zoo thiab kev ua neej nyob ntawm cov roj teeb rov qab.FEC yog ib qho tseem ceeb rau kev ruaj ntseg ntawm kev sib tshuam ntawm Li hlau anode thiab cov electrolyte, ua rau muaj kev nyab xeeb thiab ua haujlwm zoo dua.

Product Detail

Khoom cim npe

Fluoroethylene carbonate muaj ntau yam zoo dua li cov pa electrolyte additives.Ua ntej, nws tsim cov txheej tiv thaiv nyias, tseem hu ua cov khoom electrolyte interface (SEI), ntawm lithium hlau nto.Cov txheej txheem SEI no tuaj yeem tiv thaiv kev sib cuag ncaj qha ntawm lithium electrode thiab electrolyte, txo qhov kev pheej hmoo ntawm kev phiv tsis zoo thiab ua kom lub roj teeb ntev dua.

Tsis tas li ntawd, FEC pab txhim kho tag nrho cov electrochemical stability ntawm lub roj teeb.Nws cov khoom siv tshuaj zoo heev pab kom tsim tau cov txheej txheem SEI ruaj khov thiab muaj zog, yog li txo qhov degradation ntawm lithium electrodes thaum them nqi thiab tawm mus.Raws li qhov tshwm sim, cov roj teeb tuaj yeem tiv taus qhov hluav taws xob ntau dua thiab nthuav tawm kev ua haujlwm ntawm kev caij tsheb kauj vab, ua rau kev txhim kho lub zog cia thiab lub roj teeb ntev dua.

Tsis tas li ntawd, qhov sib ntxiv ntawm fluoroethylene carbonate rau cov qauv electrolyte tuaj yeem txhim kho kev nyab xeeb ntawm lithium-ion roj teeb.Los ntawm kev ua kom zoo dua cov electrolyte-electrode interface, nws inhibits qhov tsim ntawm dendrites, uas yog cov qauv zoo li rab koob uas tuaj yeem ua rau lub voj voog luv luv thiab muaj peev xwm ua rau thermal runaway.Qhov no ua rau cov roj teeb txhim khu kev qha thiab txo qhov kev pheej hmoo ntawm cov xwm txheej txaus ntshai, ua kom muaj kev thaj yeeb nyab xeeb rau cov tuam txhab thiab cov neeg siv kawg.

Hauv cov ntsiab lus, peb cov chemistry tshiab, fluoroethylene carbonate (CAS: 114435-02-8), yog ib qho kev ua si-hloov Li-ion roj teeb ntxiv.Nrog nws lub peev xwm ua kom ruaj khov ntawm electrolyte-electrode interface, txhim kho electrochemical stability, thiab txhim khu kev ruaj ntseg roj teeb, nws yog ib qho tseem ceeb uas yuav ua rau lub neej yav tom ntej ntawm lub zog cia technology.Peb muaj kev ntseeg siab tias qhov tshwj xeeb sib xyaw no yuav ua tau raws li kev lag luam kev cia siab, thiab peb tos ntsoov yuav ua haujlwm nrog koj los tsim kom muaj lub zog ruaj khov thiab muaj txiaj ntsig yav tom ntej.
