Lithium Carbonate ndi Lithium Hydroxide onse ndi zida zopangira mabatire, ndipo mtengo wa lithiamu carbonate wakhala wotchipa kuposa lithiamu hydroxide.Kodi pali kusiyana kotani pakati pa zida ziwirizi?
Choyamba, popanga, onse amatha kuchotsedwa ku lithiamu pyroxase, kusiyana kwa mtengo sikuli kwakukulu.Komabe ngati awiriwo akusinthana wina ndi mzake, mtengo wowonjezera ndi zida zimafunikira, sipadzakhala ndalama zogwirira ntchito.
Lithium carbonate makamaka opangidwa kudzera njira sulfuric asidi, amene analandira mwa zimene sulfuric asidi ndi lithiamu pyroxase, ndi sodium carbonate anawonjezera kuti lifiyamu sulphate njira, ndiyeno precipitated ndi zouma kukonzekera lithiamu carbonate;
Kukonzekera kwa lithiamu hydroxide makamaka kudzera mu njira ya alkali, ndiko kuti, kuwotcha lithiamu pyroxene ndi calcium hydroxide.Enawo amagwiritsa ntchito njira - yotchedwa sodium carbonate pressurization, ndiko kuti, kupanga lithiamu - yomwe ili ndi yankho, ndiyeno onjezerani laimu ku njira yothetsera lithiamu hydroxide.
Ponseponse, lithiamu pyroxene ingagwiritsidwe ntchito pokonzekera zonse za lithiamu carbonate ndi lithiamu hydroxide, koma njira yopangira njira ndi yosiyana, zida sizingagawidwe, ndipo palibe kusiyana kwakukulu kwa mtengo.Komanso, mtengo wa kukonzekera lithiamu hydroxide ndi mchere nyanja brine ndi apamwamba kwambiri kuposa yokonza lithiamu carbonate.
Kachiwiri, mu gawo la ntchito, high nickel ternary idzagwiritsa ntchito lithiamu hydroxide.NCA ndi NCM811 adzagwiritsa batire kalasi lithiamu hydroxide, pamene NCM622 ndi NCM523 angagwiritse ntchito onse lithiamu hydroxide ndi lithiamu carbonate.Kukonzekera kwamafuta a lithiamu iron phosphate (LFP) kumafunanso kugwiritsa ntchito lithiamu hydroxide.Nthawi zambiri, zinthu zopangidwa kuchokera ku lithiamu hydroxide nthawi zambiri zimakhala bwino.
