CAS NO: 90076-65-6 LiTFSI/Lithium Bis (trifluoromethanesulfonimide)

Nws yog ib qho imide-raws lithium ntsev, tus yam ntxwv los ntawm: tsis tshua muaj siab solubility, nws tus kheej- dissolve tom qab nqus dej, qeeb hydrolysis tus nqi, kub tsis kam, thiab corrosiveness rau lub tam sim no collector nyob rau hauv tej yam voltages. Thiab tuaj yeem muab siab - cov khoom siv electrolyte purity, kom ntseeg tau zoo ionic conductivity thiab electrochemical stability.

A.Nws tuaj yeem txhim kho qhov kev coj ua ntawm electrolyte thiab, raws li qhov me me ntawm cov khoom ntxiv, txhim kho qhov qis - qhov kub thiab txias ntawm cov electrolyte.
B.Qhov muaj peev xwm tawg tau zoo thiab ruaj khov ntawm LiTFSI hauv cov khoom siv polymer ua rau nws muaj txiaj ntsig zoo hauv cov khoom siv polymer-raws li electrolytes thiab hauv kev tshawb fawb txog qee cov khoom- xeev electrolytes.
C.As hydrophilic organic ntsev, nws muaj ntau yam kev siv hauv hluav taws xob thiab hluav taws xob.
D.Lwm yam khoom tseem ceeb ntawm LiTFSI yog nws cov dej solubility siab heev: 21 mol/L lossis ≈6 kg/L. Vim nws cov solubility siab, LiTFSI tau kawm ua ib qho electrolyte rau lithium- ion roj teeb, hnub ci hlwb, thiab cov ntawv siv zoo sib xws.

LiTFSI feem ntau yog siv los daws cov teeb meem kev ua haujlwm tsis zoo thiab teeb meem kev nyab xeeb ntawm lithium roj teeb nyob rau hauv high voltage thiab kub tsis tshua muaj huab cua txias.

Nrog rau kev siv cov roj teeb lithium hauv cov tsheb tshiab, kev siv cov khoom siv hluav taws xob tshiab thiab cov khoom siv hluav taws xob tshiab thiab cov khoom siv hluav taws xob- lub xeev, thiab kev tso tawm nrawm dua, qhov kev thov rau LiTFSI yuav nce ntxiv.

LiTFSI yuav tsum tau ceev faj tshwj xeeb txog kev tiv thaiv cov dej noo thaum siv thiab khaws cia vim tias nws muaj qhov cuam tshuam rau kev nqus dej noo, thiab thaum nws nqus dej noo, nws yuav hnov ​​​​mob nrog dej los ua corrosive thiab toxic hydrogen fluoride, uas yuav ua rau nws qhov kev ua tau zoo poob thiab cuam tshuam rau kev nyab xeeb ntawm lub roj teeb.
