Lithium Carbonate thiab Lithium Hydroxide yog ob qho tib si raw khoom rau roj teeb, thiab tus nqi ntawm lithium carbonate yeej ib txwm pheej yig dua lithium hydroxide.Qhov txawv ntawm ob yam khoom yog dab tsi?
Ua ntej, hauv cov txheej txheem tsim khoom, ob qho tib si tuaj yeem muab rho tawm los ntawm lithium pyroxase, tus nqi sib txawv tsis loj heev.Txawm li cas los xij yog tias ob qho kev hloov mus rau ib leeg, tus nqi ntxiv thiab cov khoom siv yuav tsum tau ua, yuav tsis muaj nqi ua haujlwm.
Lithium carbonate feem ntau yog tsim los ntawm sulfuric acid acid txoj kev, uas yog tau los ntawm cov tshuaj tiv thaiv ntawm sulfuric acid thiab lithium pyroxase, thiab sodium carbonate yog ntxiv rau lithium sulfate tov, thiab ces precipitated thiab qhuav los npaj lithium carbonate;
Kev npaj ntawm lithium hydroxide feem ntau yog los ntawm alkali txoj kev, uas yog, ci lithium pyroxene thiab calcium hydroxide.Lwm tus siv txoj kev - hu ua sodium carbonate pressurization, uas yog, ua lithium - muaj cov tshuaj, thiab ces ntxiv txiv qaub rau cov tshuaj los npaj lithium hydroxide.
Zuag qhia tag nrho, lithium pyroxene tuaj yeem siv los npaj ob qho tib si lithium carbonate thiab lithium hydroxide, tab sis txoj kev sib txawv, cov khoom siv tsis tuaj yeem sib koom, thiab tsis muaj qhov sib txawv loj.Tsis tas li ntawd, tus nqi ntawm kev npaj lithium hydroxide nrog ntsev pas dej brine yog ntau dua li kev npaj ntawm lithium carbonate.
Secondly, nyob rau hauv ib feem ntawm daim ntawv thov, siab nickel ternary yuav siv lithium hydroxide.NCA thiab NCM811 yuav siv roj teeb qib lithium hydroxide, thaum NCM622 thiab NCM523 tuaj yeem siv lithium hydroxide thiab lithium carbonate.Kev npaj thermal ntawm lithium hlau phosphate (LFP) cov khoom kuj yuav tsum tau siv lithium hydroxide.Feem ntau, cov khoom tsim los ntawm lithium hydroxide feem ntau ua tau zoo dua.
