Mutengesi weLithium Hydroxide muSouth Africa

Chii Chinonzi Lithium Hydroxide?

Lithium hydroxide monohydrate (LiOH·H₂O) chinhu chichena chakasimba chinogadzirwa nekushandiswa kwe lithium carbonate ne calcium hydroxide, kana zvakananga kubva mukugadzirwa kwe lithium brine. I alkali yakasimba, inonyungudika zvikuru mumvura, uye inogadzira lithium sipo dzine mafuta acids. Lithium hydroxide yemhando yebhatiri (≥56.5% LiOH, tsvina yakaderera) yave yakakosha zvikuru senzvimbo inofarirwa ye lithium yezvinhu zvine nickel cathode zvinoshandiswa mumabhatiri emagetsi echizvarwa chinotevera.

Giredhi reBhatiri — NMC & NCA Cathodes

LiOH yemhando yebhatiri ndiyo sosi yelithium inonyanya kufarirwa yekushandisa zvinhu zvine nickel cathode zvakaita seNMC (lithium nickel manganese cobalt oxide) uye NCA (lithium nickel cobalt aluminium oxide) zvinoshandiswa mumabhatiri emagetsi nemagetsi. Kusiyana nelithium carbonate, lithium hydroxide inoshanda zvakachena ne high-nickel precursors patembiricha yakaderera, zvichivandudza chimiro che cathode, kugadzikana kwecycling, uye kuwanda kwesimba - zvakakosha pakuwedzera huwandu hwekutyaira kweEV.

Mafuta eLithium & Mafuta ekuwedzera

Lithium hydroxide ndiyo inonyanya kushandiswa mukugadzira lithium grease, iyo inonyanya kushandiswa pasi rose mumabasa akawanda. LiOH inoshanda pamwe chete nemafuta acids (tallow, stearic acid, 12-hydroxystearic acid) kugadzira sipo dze lithium dzinoita kuti mafuta emineral kana synthetic base awedzere kuita mafuta akasimba, asingapindi mvura, anoshanda kwenguva refu anoshandiswa mumabheringi, chassis, uye mumichina yemaindasitiri muzvikamu zvemotokari, migodhi, uye maindasitiri.

CO₂ Kukwesha & Kushandiswa Kwemaindasitiri

Matangi eLithium hydroxide anoshandiswa kunwisa carbon dioxide munzvimbo dzakamanikana dzakadai sengarava dzemugungwa nendege dzemuchadenga, uko reaction 2LiOH + CO₂ → Li₂CO₃ + H₂O inobvisa CO₂ pahuremu hweyuniti zviri nani kupfuura soda lime. Mashandisirwo emaindasitiri anosanganisira kurapwa nemvura (pH adjustment), alkali fusion mu analytical chemistry, uye se flux mu specialty glass and ceramic formulations uko lithium hydroxide inogona kusarudzwa pane lithium carbonate nekuda kwe reactivity yayo yakananga.
