Lithium Carbonate ati Lithium Hydroxide jẹ awọn ohun elo aise mejeeji fun awọn batiri, ati idiyele ti kaboneti litiumu nigbagbogbo jẹ diẹ din owo ju litiumu hydroxide.Kini iyatọ laarin awọn ohun elo meji naa?
Ni akọkọ, ni ilana iṣelọpọ, mejeeji le fa jade lati lithium pyroxase, aafo idiyele ko tobi pupọ.Sibẹsibẹ ti awọn mejeeji ba yipada si ara wọn, iye owo afikun ati ohun elo nilo, kii yoo ni iṣẹ ṣiṣe idiyele.
Kaboneti litiumu jẹ iṣelọpọ nipasẹ ọna sulfuric acid acid, eyiti o gba nipasẹ iṣesi ti sulfuric acid ati lithium pyroxase, ati carbonate soda ti wa ni afikun si ojutu imi-ọjọ lithium sulfate, ati lẹhinna precipitated ati ki o gbẹ lati ṣeto kaboneti litiumu;
Igbaradi ti lithium hydroxide nipataki nipasẹ ọna alkali, iyẹn ni, sisun lithium pyroxene ati kalisiomu hydroxide.Awọn miiran lo ọna bẹ - ti a npe ni iṣuu soda carbonate pressurization, eyini ni, ṣe lithium - ojutu ti o ni, ati lẹhinna fi orombo wewe si ojutu lati ṣeto lithium hydroxide.
Iwoye, litiumu pyroxene le ṣee lo lati mura mejeeji litiumu carbonate ati lithium hydroxide, ṣugbọn ọna ilana yatọ, ẹrọ naa ko le pin, ati pe ko si aafo idiyele nla.Ni afikun, iye owo ti ngbaradi litiumu hydroxide pẹlu iyọ lake brine jẹ ga julọ ju igbaradi ti kaboneti litiumu.
Ni ẹẹkeji, ni apakan ti ohun elo, giga nickel ternary yoo lo lithium hydroxide.NCA ati NCM811 yoo lo batiri lithium hydroxide, nigba ti NCM622 ati NCM523 le lo mejeeji litiumu hydroxide ati lithium carbonate.Igbaradi gbona ti awọn ọja fosifeti irin litiumu (LFP) tun nilo lilo litiumu hydroxide.Ni gbogbogbo, awọn ọja ti a ṣe lati litiumu hydroxide maa n ṣiṣẹ dara julọ.
