Lithium Carbonate ndi Lithium Hydroxide zonse ndi zinthu zopangira mabatire, ndipo mtengo wa lithiamu carbonate wakhala wotsika mtengo kuposa lithiamu hydroxide. Kodi kusiyana pakati pa zinthu ziwirizi ndi kotani?
Choyamba, popanga zinthu, zonse ziwiri zimatha kuchotsedwa mu lithiamu pyroxase, kusiyana kwa mtengo si kwakukulu kwambiri. Komabe, ngati ziwirizi zisinthana, ndalama zowonjezera ndi zida zimafunika, sipadzakhala phindu lililonse.
Lithium carbonate imapangidwa makamaka kudzera mu njira ya sulfuric acid acid, yomwe imapezeka kudzera mu momwe sulfuric acid ndi lithiamu pyroxase zimachitikira, ndipo sodium carbonate imawonjezedwa mu yankho la lithiamu sulfate, kenako imaphwanyidwa ndikuumitsidwa kuti ikonze lithiamu carbonate;
Kukonzekera kwa lithiamu hydroxide makamaka kudzera mu njira ya alkali, ndiko kuti, kuwotcha lithiamu pyroxene ndi calcium hydroxide. Ena amagwiritsa ntchito njira yotchedwa sodium carbonate pressurization, ndiko kuti, kupanga yankho lokhala ndi lithiamu, kenako ndikuwonjezera laimu ku yankholo kuti akonze lithiamu hydroxide.
Ponseponse, lithiamu pyroxene ingagwiritsidwe ntchito pokonzekera lithiamu carbonate ndi lithiamu hydroxide, koma njira yochitira izi ndi yosiyana, zida sizingagawidwe, ndipo palibe kusiyana kwakukulu kwa ndalama. Kuphatikiza apo, mtengo wokonzekera lithiamu hydroxide ndi salt lake brine ndi wokwera kwambiri kuposa wokonzekera lithiamu carbonate.
Kachiwiri, mbali ina ya ntchito, ternary ya nickel yambiri idzagwiritsa ntchito lithiamu hydroxide. NCA ndi NCM811 zidzagwiritsa ntchito lithiamu hydroxide ya batri, pomwe NCM622 ndi NCM523 zitha kugwiritsa ntchito lithiamu hydroxide ndi lithiamu carbonate. Kukonzekera kutentha kwa zinthu za lithiamu iron phosphate (LFP) kumafunanso kugwiritsa ntchito lithiamu hydroxide. Kawirikawiri, zinthu zopangidwa kuchokera ku lithiamu hydroxide nthawi zambiri zimagwira ntchito bwino.
