I-Lithium Carbonate kunye ne-Lithium Hydroxide zombini zizinto ezisetyenziswa kwiibhetri, kwaye ixabiso le-lithium carbonate belisoloko liphantsi kune-lithium hydroxide. Yintoni umahluko phakathi kwezi zinto zimbini?
Okokuqala, kwinkqubo yemveliso, zombini zinokutsalwa kwi-lithium pyroxase, umsantsa weendleko awukhulu kangako. Nangona kunjalo, ukuba ezi zimbini ziyatshintshana, iindleko ezongezelelweyo kunye nezixhobo ziyafuneka, akuyi kubakho ndleko yokusebenza.
I-lithium carbonate iveliswa kakhulu ngendlela ye-sulfuric acid acid, efunyanwa ngokusabela kwe-sulfuric acid kunye ne-lithium pyroxase, kwaye i-sodium carbonate yongezwa kwisisombululo se-lithium sulfate, ize emva koko yomiswe ukuze kulungiswe i-lithium carbonate;
Ukulungiswa kwe-lithium hydroxide ikakhulu ngendlela ye-alkali, oko kukuthi, ukurosta i-lithium pyroxene kunye ne-calcium hydroxide. Ezinye zisebenzisa indlela ebizwa ngokuba yi-sodium carbonate pressurization, oko kukuthi, ukwenza isisombululo esine-lithium, uze wongeze ilayimu kwisisombululo ukulungiselela i-lithium hydroxide.
Lilonke, i-lithium pyroxene ingasetyenziselwa ukulungisa i-lithium carbonate kunye ne-lithium hydroxide, kodwa indlela yenkqubo yahlukile, izixhobo azinakwabelwana ngazo, kwaye akukho msantsa mkhulu weendleko. Ukongeza, iindleko zokulungiselela i-lithium hydroxide kunye ne-salt lake brine ziphezulu kakhulu kunokulungiselela i-lithium carbonate.
Okwesibini, kwinxalenye yokusetyenziswa, i-nickel ternary ephezulu iya kusebenzisa i-lithium hydroxide. I-NCA kunye ne-NCM811 ziya kusebenzisa i-lithium hydroxide ye-battery grade, ngelixa i-NCM622 kunye ne-NCM523 zingasebenzisa zombini i-lithium hydroxide kunye ne-lithium carbonate. Ukulungiswa kwe-thermal kweemveliso ze-lithium iron phosphate (LFP) kufuna nokusetyenziswa kwe-lithium hydroxide. Ngokubanzi, iimveliso ezenziwe nge-lithium hydroxide zihlala zisebenza ngcono.
