FAQ
CAS NO: 156783-95-8 FEMC / Carbonic acid, Methyl 2,2,2-trifluoroethyl ester ua si hauv lithium roj teeb?
FEMC muaj qhov zoo ntawm oxidative stability thiab kev nyab xeeb siab, ua rau nws muaj kev cog lus siab -siab resistant hnyav.
Dab tsi yog cov haujlwm ntawm FEMC hauv lithium roj teeb?
A. Txhim kho lub voj voog stability nyob rau hauv high voltage systems.
B.Txhim kho qhov ruaj khov ntawm qhov zoo electrode thiab txo qhov tshwm sim ntawm sab kev cuam tshuam ntawm qhov tsis zoo electrode interface.
C.Txhim cov nplaim taws-cov khoom tiv thaiv ntawm lub roj teeb kom txhim kho kev nyab xeeb tag nrho.
FEMC muaj trifluoroethyl thiab carbonate pawg hauv nws cov qauv molecular, muab nws reactivity thiab selectivity nyob rau hauv lub synthesis ntawm fluorinated zoo tshuaj. Nws yog ib qho kev cog lus fluorinated organic synthesis intermediate uas tuaj yeem siv los ua kom muaj ntau yam khoom muaj nqis - ntxiv cov tshuaj fluorinated zoo.
Cov khoom tshwj xeeb dab tsi uas cov fluorine - muaj cov qauv ntawm FEMC coj los rau hauv cov electrolyte?
Los ntawm kev siv propylene carbonate (PC) ua ib qho dopant, peb tau hloov kho lub plhaub kev daws teeb meem los ntawm FEMC, tsim lub siab -voltage resistant thiab nyab xeeb electrolyte.
Puas yog FEMC feem ntau yog siv los ua qhov kev sib tw ntawm FEMC yog dab tsi?
Kev taw qhia ntawm -CF3 pawg rau hauv nws cov qauv molecular txo cov solubility ntawm Li+, ua rau txo qis hauv electrolyte conductivity. Yog li ntawd, thaum siv FEMC ua ib co- hnyav, cov nyiaj ntxiv yuav tsum tau tswj nruj me ntsis kom sib npaug ua haujlwm.
B.In ntshiab FEMC-raws li electrolytes, Li+ yooj yim koom tes nrog FEMC, ntxiv txo LUMO zog theem ntawm lub molecule. Qhov no ua rau kom tsis tu ncua thiab irreversible decomposition ntawm cov electrolyte ntawm graphite interface, ua rau roj.
Cov teeb meem dab tsi yog FEMC lub hom phiaj los daws cov teeb meem lithium roj teeb?
Nyob rau hauv cov electrolyte, FEMC complexes nrog lithium ions, ntxiv ua rau ib tug txo nyob rau hauv lub LUMO zog theem. Yog li ntawd, cov ntshiab FEMC-raws li electrolyte tsis tu ncua decomposes ntawm graphite nto, ua rau roj tsim thiab roj teeb tsis ua hauj lwm.
