I-Lithium Carbonate ne-Lithium Hydroxide kokubili kuyizinto zokusetshenziswa zamabhethri, futhi intengo ye-lithium carbonate ibilokhu ishibhile kune-lithium hydroxide. Uyini umehluko phakathi kwezinto ezimbili?
Okokuqala, ohlelweni lokukhiqiza, zombili zingakhishwa ku-lithium pyroxase, igebe lezindleko alilikhulu kangako. Kodwa-ke uma lezi zimbili zishintshela komunye nomunye, izindleko ezengeziwe kanye nemishini kuyadingeka, ngeke kube nokusebenza kwezindleko.
I-Lithium carbonate ikhiqizwa ngokuyinhloko ngendlela ye-sulfuric acid, etholakala ngokusabela kwe-sulfuric acid ne-lithium pyroxase, futhi i-sodium carbonate yengezwa kusixazululo se-lithium sulfate, bese ihlanjululwa futhi yomiswe ukuze kulungiswe i-lithium carbonate;
Ukulungiswa kwe-lithium hydroxide ikakhulukazi ngendlela ye-alkali, okungukuthi, ukugazinga i-lithium pyroxene ne-calcium hydroxide. Abanye basebenzisa indlela - ebizwa ngokuthi i-sodium carbonate pressurization, okungukuthi, yenza i-lithium - equkethe isixazululo, bese wengeza umcako esixazululo ukulungisa i-lithium hydroxide.
Sekukonke, i-lithium pyroxene ingasetshenziswa ukulungisa kokubili i-lithium carbonate ne-lithium hydroxide, kodwa umzila wenqubo uhlukile, imishini ayikwazi ukwabiwa, futhi alikho igebe elikhulu lezindleko. Ngaphezu kwalokho, izindleko zokulungiselela i-lithium hydroxide nge-salt lake brine ziphakeme kakhulu kunokulungiswa kwe-lithium carbonate.
Okwesibili, ingxenye yesicelo, i-nickel ternary ephezulu izosebenzisa i-lithium hydroxide. I-NCA ne-NCM811 zizosebenzisa i-lithium hydroxide yezinga lebhethri, kuyilapho i-NCM622 ne-NCM523 ingasebenzisa kokubili i-lithium hydroxide ne-lithium carbonate. Ukulungiswa okushisayo kwemikhiqizo ye-lithium iron phosphate (LFP) nakho kudinga ukusetshenziswa kwe-lithium hydroxide. Ngokuvamile, imikhiqizo eyenziwe nge-lithium hydroxide ngokuvamile yenza kangcono.
