Ushintsho lomhlaba olubheke ekusebenziseni ugesi namandla avuselelekayo selubeke izinto ezisekelwe ku-lithium ekuqhakazeni kwezimboni zesimanje. Phakathi kwezinto ezibalulekile, i-lithium hydroxide isiyisithako esibalulekile sobuchwepheshe bebhethri yesizukulwane esilandelayo, ikakhulukazi ekukhiqizeni izinto ze-cathode ezinama-nickel amaningi ezisebenzisa izimoto zikagesi kanye nezinhlelo ezinkulu zokugcina amandla. Njengoba abakhiqizi bezimishini bephokophela ukuba namandla aphezulu, isikhathi eside sokusebenza, nokuzinza okuthuthukisiwe kwezinga lokushisa, isidingo se-lithium hydroxide esezingeni eliphezulu siqhubeka nokukhula ezindaweni zokuhlinzekwa komhlaba wonke. Lesi sihloko sihluza izisekelo zamakhemikhali, izinhlobonhlobo zezicelo, kanye nezinzuzo zokuncintisana ze-lithium hydroxide, ngenkathi kugcizelelwa ukuthi i-Shanghai Oujin Lithium Industrial Co., Ltd. ihlinzeka ngeziphuzo eziphakeme kakhulu ezihlangabezana namazinga aqinile emikhakha yebhethri yesimanje nezimboni.

I-lithium hydroxide (LiOH) iyinhlanganisela ye-alkaline engaphili, ebonakala njenge-solid emhlophe, engenaphunga, eyenziwe ngamakristalu ngaphansi kwezimo ezijwayelekile. Ihlukaniswa njengesisekelo esinamandla, esincibilika kalula emanzini ukuze sikhiqize izixazululo ze-alkaline ezinomlinganiso ophakeme we-pH. Le nhlanganisela ikhona ikakhulukazi ngezindlela ezimbili ezithengiswayo: i-lithium hydroxide eyomile (LiOH) kanye ne-lithium hydroxide monohydrate (LiOH·H₂O). Uhlobo olomile alunawo amanzi okwenziwa amakristalu futhi lunokuqukethwe okuphezulu kwe-lithium esebenzayo, okwenza kube kuhle kakhulu ezinhlelweni ezidinga okokufaka kwe-lithium okugxilile. Uhlobo lwe-monohydrate, oluhlanganisa imolekyuli eyodwa yamanzi ngeyunithi yefomula, lusetshenziswa kabanzi ekwenzeni ama-cathode ebhethri ngenxa yokuqina kwalo, ukulula kokuliphatha, kanye nokusabela okungaguquki ngesikhathi senqubo ye-calcination. Zombili izindlela zibonisa i-hygroscopicity enamandla, okusho ukuthi zithatha kalula umswakama ne-carbon dioxide emoyeni ongazungezile, ngakho-ke ukugcinwa kahle ezindaweni ezivaliwe, ezomile kubalulekile ukugcina ubumsulwa. Ukukhiqizwa kwe-lithium hydroxide esezingeni eliphezulu kuvame ukubandakanya ukuguqulwa kwe-lithium carbonate ngokusebenzisa ukusabela kwe-causticization nge-calcium hydroxide, okulandelwa izigaba zokwenziwa kwamakristalu, ukuhlunga, nokomisa. Abakhiqizi abathuthukile njenge-Shanghai Oujin Lithium Industrial Co., Ltd. basebenzisa izilawuli eziqinile zenqubo kuzo zonke izigaba ukuze bafeze ubumsulwa obudlula u-99.5%, baqinisekise ukuthi abakhiqizi abalandelayo bathola impahla eluhlaza engaguquki futhi ethembekile yezinqubo zabo ezibalulekile.

Ngokombono wokuphepha kanye nemithetho, i-lithium hydroxide ihlukaniswa njenge-substance enobudlova edinga izinqubo zokuphatha eziqaphile. Ingadala ukulimala okubi esikhunjeni kanye nomonakalo emehlweni lapho kuthintana ngqo, futhi ukuhogelwa kotshani bayo kufanele kugwenywe ngokusebenzisa umoya owanele kanye nemishini yokuzivikela yomuntu. Naphezu kwezidingo zokuphatha, indima engashintshwa yale compound ekugcineni kwamandla aphezulu kuyenza ibe yinye yezinto ezihweba kakhulu ezivela ku-lithium emakethe omhlaba. Imakethe yomhlaba wonke ye-lithium hydroxide ibone ukukhula okukhulu emashumini eminyaka adlule, okushukunyiswa ikakhulukazi yi-EV revolution kanye nokwamukelwa okwandayo kwezinhlanganisela ze-cathode ezicebile nge-nickel ezidinga lo mthombo we-lithium ngaphezu kwezinye izindlela. Ukuqonda izici ezihlukile zohlobo ngalunye lwe-lithium hydroxide kwenza amaqembu okuthenga kanye nonjiniyela bebhethri bakwazi ukukhetha izinga elihle kakhulu lezinhlelo zabo ezithile zokukhiqiza, balinganise ukusabela, izindleko, kanye nezinto zokuthutha.

Isicelo esivelele kakhulu nesikhula ngokushesha kakhulu se-lithium hydroxide sitholakala ekukhiqizeni izinto zekhodi ezinama-nickel aphezulu njenge-NCM (nickel-cobalt-manganese) ne-NCA (nickel-cobalt-aluminum). Lezi zindlela zekhodi ziyisisekelo samabhethri e-lithium-ion anamuhla asetshenziswa ezimotweni zikagesi, ezinhlelweni zokugcina amandla esikali esikhulu, kanye nezinto zikagesi eziphathekayo. Ngokungafani ne-lithium carbonate, okuyiyona mthombo we-lithium okhethwayo wezindlela zekhodi ezinama-nickel aphansi njenge-LFP (lithium iron phosphate) ne-NCM-111, i-lithium hydroxide yenza kube lula ukuhlanganiswa kwama-oxide anama-nickel amaningi anomsebenzi ongcono kakhulu we-electrochemical. Ukusetshenziswa kwe-lithium hydroxide ekukhiqizeni ikhodi kunciphisa izinga lokushisa lokuhlanganisa elidingekayo, kunciphisa ukuthutha kwama-ion amatshe ayisisekelo, futhi kukhuthaza ukwakheka kwesakhiwo samakristalu esihle esithuthukisa ukugcinwa kwamandla kanye nekhono lokusebenza ngesivinini. Amaseli ebhethri akhiqizwa ngamakhodi atholakala ku-lithium hydroxide abonisa njalo amandla aphezulu kakhulu, ukuzinza okuthuthukisiwe komjikelezo, kanye nokusebenza okungcono ngaphansi kwezimo zokusebenza zamandla aphezulu. Njengoba abakhiqizi bezimoto bejaha ukwandisa ibanga lokushayela nokunciphisa izikhathi zokushaja, ukuguqukela ezindleleni zekhodi ezinama-nickel amaningi kuye kwaba yinto enkulu embonini, okuqondisa ngqo isidingo se-lithium hydroxide esezingeni lebhethri emhlabeni wonke. Abahlaziyi bemboni balinganisela ukuthi isabelo se-lithium hydroxide esetshenziswa esidingweni sonke se-lithium samabhethri sizodlula u-60% ngaphakathi kwalo mdlalo, okugcizelela ukubaluleka kwayo kwezinguquko zamandla.

Ngaphandle kwendima yayo ebalulekileyo kubuchwepheshe bebhetri, i-lithium hydroxide isebenza njengesisekelo esisebenzayo ezimbonini eziningi. Enye yezinto ezisetshenziswa isikhathi eside ukukhiqiza amafutha okugcoba asekelwe ku-lithium, lapho i-lithium hydroxide isabela khona nama-fatty acids ukwakha izinto ezijiyisayo ze-lithium soap. Amafutha la abonisa ukumelana kahle namanzi, ukuzinza ezingeni lokushisa eliphezulu, namandla okumelana nokucindezelwa komshini, okwenza abe yisidingo ezindaweni zezimoto, imishini yezimboni, kanye nezindiza. Enye indawo ebalulekile ihlanganisa ukumunca i-carbon dioxide (CO₂) ezindaweni ezivalekile njengezikebhe zokucwilisa, izindiza zomkhathi, kanye nezinhlelo zokuphefumula kabusha. I-lithium hydroxide isabela ngokushesha ne-CO₂ ukwakha i-lithium carbonate namanzi, okusula umoya wale nto eyimfucuza yomzimba. Leli khono lekhemikhali libuye lisetshenziswe ezinhlelweni zokuhlanza igesi ezindaweni zemvelo nezimboni. Embonini yezemithi, i-lithium hydroxide iyisisekelo ekwenzeni imithi ehlukahlukene esekelwe ku-lithium, okubalwa phakathi kwalokho okusetshenziselwa ukwelapha i-bipolar disorder nezinye izimo zezinzwa. Imboni yengilazi neyemikhiqizo yobumba isebenzisa i-lithium hydroxide njengesisekelo sokunciphisa amazinga okuncibilika, ukuthuthukisa izakhiwo zokunweba ngenxa yokushisa, nokuthuthukisa ukuqina kwemikhiqizo eqediwe. Ukusebenza okuhlukahlukene kwe-lithium hydroxide kulezi zimboni ezahlukene kudala isidingo esiningi esinciphisa ukungazinzi kwemakethe futhi sisekele ukutshalwa kwezimali esikhathini eside emandleni okukhiqiza.

Umbuzo obalulekile ovame ukuvela phakathi kwabakhiqizi bebhethri kanye nochwepheshe bokuthenga ukuthi kungani i-lithium hydroxide ikhethwa kakhulu kunama-lithium carbonate ezicelo ezinamandla aphezulu. Impendulo itholakala ekuziphatheni okuhlukile kwamakhemikhali kwalezi zinhlanganisela ezimbili ze-lithium ngesikhathi sokwenziwa kwe-cathode. Lapho kukhiqizwa ama-cathode e-NCM noma i-NCA aphezulu kwi-nickel, inqubo ye-calcination idinga umthombo we-lithium ongasebenza kahle nesibonelo se-hydroxide esixubile emazingeni okushisa avame ukusuka ku-700°C kuye ku-950°C. I-lithium hydroxide iyabola emazingeni okushisa aphansi futhi ibonisa ukusebenza okuphezulu kune-lithium carbonate, okuvumela ukuthi i-lithiumization ephelele kakhulu yesakhiwo somphathi we-cathode. Lokhu kusebenza okuthuthukisiwe kuguqulela ngqo kumandla aphezulu, ukuxubana okuphansi kwe-cation, kanye nokunciphisa izinhlanganisela ze-lithium ezisele ebusweni be-cathode, konke lokhu kunomthelela ekusebenzeni okungcono kwebhethri nasekuphileni okude. Ngaphezu kwalokho, ukusetshenziswa kwe-lithium hydroxide kunciphisa ukukhishwa kwe-CO₂ ngesikhathi se-calcination, okungadala izimbobo kanye neziphazamiso zesakhiwo kumagundane e-cathode uma kungalawulwa kahle. Iphuzu eliphansi lokuncibilika kwe-lithium hydroxide futhi lenza kube lula ukumanzisa okungcono nokungena kumagundane esibonelo, okuholela ekusabalalisweni okulinganayo kwezinto kanye nokuhlangana okungcono kwe-electrochemical kuwo wonke ama-electrode. Ezinhlanganisweni eziphezulu ze-nickel lapho okuqukethwe kwe-nickel kudlula u-80%, i-lithium hydroxide ayizuzisi nje kuphela kodwa iyadingeka ukuze kufezekiswe izici ezifunwayo ze-electrochemical. Abakhiqizi bamabhethri abashintsha kusuka ku-lithium carbonate baye ku-lithium hydroxide njalo babika ukwanda kwamandla angu-5% kuye ku-15% kuwo, kanye nokuthuthuka okubonakalayo ekuphileni komjikelezo kanye nemingcele yokuphepha.
