ʻO ka Lithium Carbonate a me ka Lithium Hydroxide nā mea waiwai ʻelua no nā pila, a ʻoi aku ka liʻiliʻi o ke kumukūʻai o ka lithium carbonate 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 kiʻi ʻia ʻelua mai ka lithium pyroxase, ʻaʻole nui ka nui o ke kumukūʻai. Eia naʻe inā hoʻololi nā mea ʻelua i kekahi i kekahi, pono ke kumu kūʻai hou a me nā mea hana, ʻaʻohe hana uku.
Hoʻokumu nui ʻia ka lithium carbonate ma o ka sulfuric acid acid method, i loaʻa ma o ka hopena o ka sulfuric acid a me ka lithium pyroxase, a hoʻohui ʻia ka sodium carbonate i ka solution lithium sulfate, a laila hoʻomaloʻo ʻia a maloʻo e hoʻomākaukau i ka lithium carbonate;
ʻO ka hoʻomākaukau ʻana i ka lithium hydroxide ma o ke ʻano alkali, ʻo ia hoʻi, ka ʻai ʻana i ka lithium pyroxene a me ka calcium hydroxide. Hoʻohana ka poʻe ʻē aʻe i ke ʻano - i kapa ʻia ʻo sodium carbonate pressurization, ʻo ia hoʻi, e hana i ka hopena 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 no ka hoʻomākaukau ʻana i ka lithium carbonate a me ka lithium hydroxide, akā ʻokoʻa ke ala kaʻina hana, ʻaʻole hiki ke hoʻokaʻawale ʻia nā mea hana, ʻaʻohe kumu kūʻai nui. Eia kekahi, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka hoʻomākaukau ʻana i ka lithium hydroxide me ka wai paʻakai paʻakai ma mua o ka hoʻomākaukau ʻana i ka lithium carbonate.
ʻO ka lua, ma kahi o ka noi, e hoʻohana ka nickel ternary kiʻekiʻe i ka lithium hydroxide. E hoʻohana ʻo NCA a me NCM811 i ka lithium hydroxide papa pākahi, a hiki i ka NCM622 a me NCM523 ke hoʻohana i ka lithium hydroxide a me ka lithium carbonate. Pono ka hoʻomākaukau wela o nā huahana lithium iron phosphate (LFP) i ka hoʻohana ʻana i ka lithium hydroxide. ʻO ka maʻamau, ʻoi aku ka maikaʻi o nā huahana i hana ʻia mai ka lithium hydroxide.
