I-Lithium Carbonate kanye ne-Lithium Hydroxide zombili ziyizinto zokusetshenziswa zamabhethri, futhi intengo ye-lithium carbonate ibilokhu ishibhile kancane kune-lithium hydroxide. Uyini umehluko phakathi kwalezi zinto ezimbili?
Okokuqala, enqubweni yokukhiqiza, zombili zingakhishwa ku-lithium pyroxase, igebe lezindleko alilikhulu kangako. Kodwa-ke uma lokhu kushintshelana, kudingeka izindleko ezengeziwe kanye nemishini, ngeke kube nokusebenza kwezindleko.
I-lithium carbonate ikhiqizwa kakhulu ngendlela ye-sulfuric acid acid, etholakala ngokusabela kwe-sulfuric acid kanye ne-lithium pyroxase, bese i-sodium carbonate ingezwa esixazululweni se-lithium sulfate, bese ishiswa bese yomiswa ukuze kulungiselelwe i-lithium carbonate;
Ukulungiswa kwe-lithium hydroxide ikakhulukazi ngendlela ye-alkali, okungukuthi, ukuthosa i-lithium pyroxene kanye ne-calcium hydroxide. Abanye basebenzisa indlela ebizwa ngokuthi i-sodium carbonate pressurization, okungukuthi, ukwenza isixazululo esiqukethe i-lithium, bese befaka i-lime esixazululweni ukulungiselela i-lithium hydroxide.
Sekukonke, i-lithium pyroxene ingasetshenziswa ukulungiselela i-lithium carbonate kanye ne-lithium hydroxide, kodwa indlela yenqubo ihlukile, imishini ayikwazi ukwabelwana ngayo, futhi akukho sikhala esikhulu sezindleko. Ngaphezu kwalokho, izindleko zokulungiselela i-lithium hydroxide nge-salt lake brine ziphakeme kakhulu kunokulungiselela i-lithium carbonate.
Okwesibili, engxenyeni yokusetshenziswa, i-nickel ternary ephezulu izosebenzisa i-lithium hydroxide. I-NCA kanye ne-NCM811 zizosebenzisa i-lithium hydroxide yebanga lebhethri, kuyilapho i-NCM622 kanye ne-NCM523 zingasebenzisa i-lithium hydroxide kanye ne-lithium carbonate. Ukulungiswa kwemikhiqizo ye-lithium iron phosphate (LFP) ngokushisa nakho kudinga ukusetshenziswa kwe-lithium hydroxide. Ngokuvamile, imikhiqizo eyenziwe nge-lithium hydroxide ivame ukusebenza kangcono.
