Umahluko phakathi kweBanga lebhetri iLithium Carbonate kunye neLithium Hydroxide

I-Lithium Carbonate kunye neLithium Hydroxide zombini zizixhobo ezikrwada zeebhetri, kwaye ixabiso le-lithium carbonate belisoloko linexabiso eliphantsi kune-lithium hydroxide. Uthini umahluko phakathi kwezi zinto zimbini?

Okokuqala, kwinkqubo yokuvelisa, zombini zinokukhutshwa kwi-lithium pyroxase, i-gap yeendleko ayinkulu kakhulu. Nangona kunjalo ukuba ezimbini zitshintshela omnye komnye, iindleko ezongezelelweyo kunye nezixhobo ezifunekayo, akuyi kuba neendleko zokusebenza.

I-lithium carbonate iveliswa ikakhulu ngendlela ye-asidi ye-sulfuric, efumaneka ngokusabela kwe-sulfuric acid kunye ne-lithium pyroxase, kunye ne-sodium carbonate yongezwa kwisisombululo se-lithium sulfate, kwaye emva koko i-precipitated kwaye yomiswe ukulungiselela i-lithium carbonate;

Ukulungiswa kwe-lithium hydroxide ngokukodwa ngokusebenzisa indlela ye-alkali, oko kukuthi, ukutshisa i-lithium pyroxene kunye ne-calcium hydroxide. Abanye basebenzisa indlela ebizwa ngokuba yi-sodium carbonate pressurization, oko kukuthi, yenza i-lithium - equlethe isisombululo, kwaye ungeze i-lime kwisisombululo ukulungiselela i-lithium hydroxide.

Ngokubanzi, i-lithium pyroxene ingasetyenziselwa ukulungiselela zombini i-lithium carbonate kunye ne-lithium hydroxide, kodwa indlela yenkqubo ihluke, izixhobo azikwazi ukwabelwana, kwaye akukho ntlawulo enkulu yeendleko. Ukongeza, iindleko zokulungiselela i-lithium hydroxide ngetyuwa ye-lake brine iphezulu kakhulu kunokulungiswa kwe-lithium carbonate.

Okwesibini, inxalenye yesicelo, i-nickel ternary ephezulu iya kusebenzisa i-lithium hydroxide. I-NCA kunye ne-NCM811 iya kusebenzisa ibhetri ye-lithium hydroxide, ngelixa i-NCM622 kunye ne-NCM523 ingasebenzisa zombini i-lithium hydroxide kunye ne-lithium carbonate. Ukulungiswa kwe-thermal ye-lithium iron phosphate (LFP) iimveliso nazo zifuna ukusetyenziswa kwe-lithium hydroxide. Ngokuqhelekileyo, iimveliso ezenziwe kwi-lithium hydroxide zihlala zisebenza ngcono.
