Umhlinzeki we-Lithium Hydroxide eNingizimu Afrika

Kuyini i-Lithium Hydroxide?

I-Lithium hydroxide monohydrate (LiOH·H₂O) iyi-white granular solid ekhiqizwa yi-causticization ye-lithium carbonate ne-calcium hydroxide, noma ngokuqondile ekucutshungulweni kwe-lithium brine. Iyi-alkali enamandla, encibilika kakhulu emanzini, futhi yakha insipho ye-lithium enama-fatty acid. I-lithium hydroxide yezinga lebhethri (≥56.5% LiOH, ukungcola okuphansi kakhulu) isibe yinto ebaluleke kakhulu njengomthombo we-lithium okhethwayo wezinto ze-cathode ze-nickel ezisetshenziswa kumabhethri ezimoto zikagesi zesizukulwane esilandelayo.

Izinga Lebhethri — Ama-NMC nama-NCA Cathodes

I-LiOH esezingeni lebhethri ingumthombo we-lithium okhethwayo wezinto ze-cathode ezine-nickel ephezulu njenge-NMC (i-lithium nickel manganese cobalt oxide) kanye ne-NCA (i-lithium nickel cobalt aluminium oxide) ezisetshenziswa kumabhethri okugcina izimoto zikagesi kanye nesitoreji samandla. Ngokungafani ne-lithium carbonate, i-lithium hydroxide isabela ngokuhlanzekile kakhulu ngama-precursors ane-nickel ephezulu emazingeni okushisa aphansi, okuthuthukisa isimo se-cathode, ukuzinza kokujikeleza, kanye nobuningi bamandla - okubalulekile ekwandiseni ibanga lokushayela le-EV.

Ama-Lithium Greases nama-Lubricant

I-Lithium hydroxide iyi-ejenti eyinhloko yokwenza i-saponifying ekukhiqizweni kwamafutha e-lithium, amafutha ezinhloso eziningi asetshenziswa kakhulu emhlabeni. I-LiOH isabela nama-fatty acid (i-tallow, i-stearic acid, i-12-hydroxystearic acid) ukuze yakhe insipho ye-lithium eqinisa amafutha amaminerali noma ayisisekelo sokwenziwa abe amafutha aqinile, angangeni manzi, asebenza isikhathi eside asetshenziswa kuma-bearings, chassis, kanye nemishini yezimboni kuzo zonke izimboni zezimoto, izimayini, kanye nezimboni.

Izicelo Zokuhlafuna ze-CO₂ Nezimboni

Ama-canister e-lithium hydroxide asetshenziselwa ukumunca i-carbon dioxide ezindaweni ezivalekile njengemikhumbi-ngwenya kanye nemikhumbi-mkhathi, lapho ukusabela okungu-2LiOH + CO₂ → Li₂CO₃ + H₂O kususa i-CO₂ ngesisindo seyunithi ngayinye ngempumelelo kakhulu kune-soda lime. Izicelo zezimboni zifaka phakathi ukwelashwa kwamanzi (ukulungiswa kwe-pH), ukuhlanganiswa kwe-alkali kumakhemikhali okuhlaziya, kanye nokushintshashintsha kwengilazi ekhethekile kanye ne-ceramic formulations lapho i-lithium hydroxide ingathandwa kune-lithium carbonate ngenxa yokusabela kwayo ngqo.
