ʻO ka Lithium Carbonate a me ka Lithium Hydroxide nā mea maka no nā pila, a ʻo ke kumukūʻai o ka lithium carbonate ua emi mau ka haʻahaʻa ma mua o ka lithium hydroxide. He aha ka ʻokoʻa ma waena o nā mea ʻelua?
ʻO ka mea mua, i ke kaʻina hana, hiki ke unuhi ʻia nā mea ʻelua mai ka lithium pyroxase, ʻaʻole nui ka ʻokoʻa kumukūʻai. Eia naʻe inā hoʻololi nā mea ʻelua kekahi i kekahi, pono ke kumukūʻai hou a me nā lako, ʻaʻohe hana kumukūʻai.
Hoʻopuka nui ʻia ka Lithium carbonate ma o ke ʻano waikawa sulfuric acid, i loaʻa ma o ka hopena o ka sulfuric acid a me ka lithium pyroxase, a hoʻohui ʻia ka sodium carbonate i ka hopena lithium sulfate, a laila hoʻomoʻa ʻia a maloʻo e hoʻomākaukau i ka lithium carbonate;
ʻO ka hoʻomākaukau ʻana o ka lithium hydroxide ma o ke ʻano alkali, ʻo ia hoʻi, ke kālua ʻana i ka lithium pyroxene a me ka calcium hydroxide. Hoʻohana nā mea ʻē aʻe i ke ʻano i kapa ʻia ʻo sodium carbonate pressurization, ʻo ia hoʻi, hana i ka hopena i loaʻa ka lithium, a laila hoʻohui i ka lime i ka hopena e hoʻomākaukau ai i ka lithium hydroxide.
Ma keʻano holoʻokoʻa, hiki ke hoʻohana ʻia ka lithium pyroxene e hoʻomākaukau i ka lithium carbonate a me ka lithium hydroxide, akā ʻokoʻa ke ala hana, ʻaʻole hiki ke kaʻana like ʻia nā lako, a ʻaʻohe ʻokoʻa kumukūʻai nui. Eia kekahi, ʻoi aku ke kiʻekiʻe o ke kumukūʻai o ka hoʻomākaukau ʻana i ka lithium hydroxide me ka brine loko paʻakai ma mua o ka hoʻomākaukau ʻana o ka lithium carbonate.
ʻO ka lua, ma kahi ʻāpana o ka noi, e hoʻohana ka nickel ternary kiʻekiʻe i ka lithium hydroxide. E hoʻohana ʻo NCA lāua ʻo NCM811 i ka lithium hydroxide papa pākahiko, ʻoiai hiki iā NCM622 lāua ʻo NCM523 ke hoʻohana i ka lithium hydroxide a me ka lithium carbonate. Pono pū ka hoʻomākaukau wela o nā huahana lithium iron phosphate (LFP) i ka hoʻohana ʻana i ka lithium hydroxide. Ma keʻano laulā, ʻoi aku ka maikaʻi o nā huahana i hana ʻia mai ka lithium hydroxide.
