Lithium Hydroxide siv rau dab tsi?
1. Los tsim cov sib txawv lithium compounds thiab lithium ntsev:
Lithium Hydroxide yog siv rau hauv kev tsim cov lithium ntsev ntawm stearic thiab ntxiv fatty acids. Tsis tas li ntawd, lithium hydroxide feem ntau yog siv los tsim cov khoom sib txawv lithium thiab lithium ntsev, nrog rau lithium soaps, lithium-based greases thiab alkyd resins. Thiab nws yog dav siv raws li catalysts, yees duab developers, tsim cov neeg sawv cev rau spectral tsom xam, additives nyob rau hauv alkaline roj teeb.
2. Los tsim cov khoom siv cathode rau cov roj teeb lithium-ion:
Lithium Hydroxide feem ntau yog siv los tsim cov khoom siv cathode rau lithium-ion roj teeb xws li lithium cobalt oxide (LiCoO2) thiab lithium hlau phosphate. Raws li cov khoom siv ntxiv rau alkaline roj teeb electrolyte, lithium hydroxide tuaj yeem ua kom muaj zog hluav taws xob los ntawm 12% mus rau 15% thiab roj teeb lub neej ntawm 2 lossis 3 zaug. Lithium hydroxide roj teeb qib, nrog qis melting point, tau txais prevailingly txais raws li ib tug zoo electrolyte cov ntaub ntawv nyob rau hauv NCA, NCM lithium-ion roj teeb tsim, uas enables npib tsib xee-nplua nuj lithium roj teeb muaj zog zoo dua lithium carbonate; thaum kawg tseem yog qhov kev xaiv tseem ceeb rau LFP thiab ntau lwm cov roj teeb kom deb li deb.
3. Roj:
Ib qho nrov lithium roj thickener yog lithium 12-hydroxystearate, uas ua rau lub hom phiaj dav dav lubricating roj vim nws cov dej tsis kam thiab muaj txiaj ntsig ntawm qhov kub thiab txias. Cov no yog siv los ua cov thickener hauv lubricating roj. Lithium roj muaj ntau lub hom phiaj. Nws muaj qhov kub thiab txias thiab dej tsis kam thiab nws tseem tuaj yeem txhawb nqa kev kub ntxhov, ua rau nws haum rau ntau yam lag luam. Nws yog tshwj xeeb tshaj yog siv hauv kev lag luam tsheb thiab tsheb.
4. Carbon dioxide txhuam:
Lithium Hydroxide yog siv nyob rau hauv ua pa roj purification systems rau spacecraft, submarines, thiab rebreathers kom tshem tawm carbon dioxide los ntawm exhaled roj los ntawm ua lithium carbonate thiab dej. Lawv kuj yog siv los ua ib qho additive nyob rau hauv electrolyte ntawm alkaline roj teeb. Nws tseem paub tias yog carbon dioxide scrubber. Cov khoom ci lithium hydroxide tuaj yeem siv los ua cov pa roj carbon dioxide absorbent rau cov neeg ua haujlwm hauv lub nkoj thiab cov nkoj hauv nkoj. Cov pa roj carbon dioxide tuaj yeem nqus tau yooj yim hauv cov pa uas muaj dej vapor.
5. Lwm yam kev siv:
Nws kuj yog siv hauv ceramics thiab qee qhov Portland cement formulations. Lithium hydroxide (isotopically enriched nyob rau hauv lithium-7) yog siv rau alkalize lub reactor coolant nyob rau hauv cov dej pressurized reactors rau corrosion tswj.
