Lub npe tshuaj: Lithium tetrafluoroborate
Lub npe Askiv: Lithium tetrafluoroborate
CAS Nr .: 14283-07-9
Cov tshuaj formula: LiBF4
Molecular Luj: 93.75 g / mol
Cov tsos mob: dawb los yog daj hmoov
Lithium Tetrafluoroborate (LiBF4) yog cov hmoov dawb los yog daj me ntsis, yooj yim soluble hauv dej, muaj solubility zoo nyob rau hauv carbonate cov kuab tshuaj thiab ether tebchaw, muaj ib tug melting point ntawm 293-300 ° C, thiab ib tug txheeb ze ntom ntawm 0.852 g / cm3.
Lithium tetrafluoroborate muaj tshuaj lom neeg ruaj khov thiab thermal stability, thiab feem ntau yog siv los ua ib qho ntxiv hauv LiPF6 raws li electrolyte system los txhim kho lub neej voj voog thiab txhim kho kev ua haujlwm ntawm lithium ion roj teeb.Tom qab ntxiv LiBF4 rau electrolyte, qhov kub thiab txias ua haujlwm ntawm lithium ion roj teeb tuaj yeem nthuav dav, thiab kev ua haujlwm siab thiab qis qis ntawm lub roj teeb tuaj yeem txhim kho.
