FAQ
1.Dab tsi yog qhov tseem ceeb tshaj plaws ntawm LiFSI hauv lithium roj teeb electrolytes
A.High hluav taws xob conductivity;
B.Zoo qis-kev ua haujlwm kub;
C.Resistance rau hydrolysis, thiab lwm yam.
2.Kev Npaj LiFSI thiab nws cov kev sib tw uas cuam tshuam:
Cov txheej txheem kev npaj rau LiFSI feem ntau koom nrog thawj qhov kev sib txuas ntawm dichlorosulfonylimide, ua raws li cov txheej txheem fluorination thiab lithiation kom tau txais cov khoom. Cov txheej txheem no suav nrog ntau cov kauj ruam, nyuaj, thiab ua rau cov khoom lag luam qis.
Lub LiFSI npaj siv cov txheej txheem uas twb muaj lawm muaj tsawg purity; impurities xws li chloride ions thiab insoluble tshuaj muaj peev xwm corrode lub txhuas tam sim no collector, yog li txo qhov kev ua tau zoo ntawm lithium{0}} ion roj teeb.
3.Vim li cas LiFSI thiaj suav hais tias yog kev cog lus tshiab lithium ntsev los hloov LiPF6?
LiFSI tuaj yeem siv los ua ib qho electrolyte ntawm nws tus kheej, thiab nws nthuav tawm cov kev ua tau zoo ntawm electrolyte, txhim kho cov cim tseem ceeb xws li electrolyte conductivity, siab thiab qis -kub kev ua haujlwm, thiab hydrolysis tsis kam. Nws kuj suppresses roj tiam, ua tau zoo raws li cov kev xav tau ntawm cov roj teeb uas muaj zog ntxiv.
