ʻO nā pākahi Lithium ka ʻenehana ʻenehana kiʻekiʻe loa i kēia lā, me ke kiʻekiʻe o ka ikehu kiʻekiʻe, ke ola lōʻihi, ka haʻahaʻa haʻahaʻa haʻahaʻa, ka palekana o ke kaiapuni a me nā pono ʻē aʻe.Hoʻohana nui ʻia lākou i nā kelepona akamai, laptops a me nā huahana uila ʻē aʻe, a me nā kaʻa ikehu hou a me ka ikehu makani, ka ikehu o ka lā a me nā mea mālama ikehu nui ʻē aʻe.Me nā pahuhopu hōʻemi kalapona honua, hoʻololi electrification a me nā hoʻoponopono kulekele, ke hōʻike nei ka noi ʻana o ka mākeke lithium i ka ulu pahū.Manaʻo ʻia e 2025, hiki i ka nui o ka mākeke pākahi lithium honua i 1.1 trillion US kālā.
ʻAʻole hilinaʻi ka hana a me ka maikaʻi o nā pā lithium i ka hana a me ka paʻa o nā ion lithium, akā i ke koho a me ka ratio o nā mea pākaukau.I waena o lākou, ʻo ka magnesium carbonate kahi mea pākaukau koʻikoʻi, i hoʻohana nui ʻia e hana i ka precursor o nā mea electrode maikaʻi, a hiki ke hoʻohana ʻia e hoʻomaikaʻi i ke ʻano a me ka conductivity o nā mea electrode maikaʻi ʻole.He kuleana koʻikoʻi ka Magnesium carbonate i nā pā lithium, akā pehea e koho ai i ka magnesium carbonate kiʻekiʻe?Eia kekahi mau ʻōlelo aʻoaʻo:
- E nānā inā paʻa ka ʻike nui o ka magnesium carbonate.ʻO ka ʻike nui o ka magnesium carbonate e pili ana i ka ʻike o nā ion magnesium, i hoʻomalu ʻia ma waena o 40-42%.ʻO ke kiʻekiʻe a i ʻole ka haʻahaʻa o ka magnesium ion content e hoʻopilikia i ka ratio a me ka hana o nā mea electrode maikaʻi.No laila, i ke koho ʻana i ka magnesium carbonate, koho i kēlā mau mea hana me ka ʻenehana hana kiʻekiʻe a me ka pae ʻenehana.Hiki iā lākou ke hoʻopaʻa pono i ka ʻona magnesium ion o ka magnesium carbonate a hōʻoia i ka maikaʻi o ka maloʻo huahana a me ka wehe ʻana i ka haumia.
- E nānā inā mālama ʻia nā haumia magnetic o ka magnesium carbonate ma kahi haʻahaʻa.ʻO nā mea haumia magnetic e pili ana i nā mea metala a i ʻole nā hui e like me ka hao, cobalt, nickel, a me nā mea ʻē aʻe, e hoʻopilikia i ka wikiwiki o ka neʻe ʻana a me ka pono o nā ion lithium ma waena o nā electrodes maikaʻi a maikaʻi ʻole, e hōʻemi i ka hiki a me ke ola o nā pā.No laila, i ke koho ʻana i ka magnesium carbonate, e koho i kēlā mau huahana me nā haumia magnetic ma lalo o 500 ppm (hoʻokahi i loko o ka miliona), a hōʻoia iā lākou e nā mea hana hoʻokolohua.
- E nānā inā he haʻahaʻa ka nui o ka magnesium carbonate.E hoʻopili ka nui o ka magnesium carbonate i ka morphology a me ka crystallinity o nā mea electrode maikaʻi, a laila pili i ka hana hoʻoiho a me ka paʻa o ka pōʻai.No laila, i ke koho ʻana i ka magnesium carbonate, e koho i kēlā mau huahana me ka liʻiliʻi liʻiliʻi liʻiliʻi a me ka nui like me nā mea ʻē aʻe.Ma ka ʻōlelo maʻamau, ʻo ka nui o ka nui D50 (ʻo ia hoʻi, 50% ka nui o ka hoʻohele kumulative particle) o ka magnesium carbonate ma kahi o 2 microns, D90 (ie, 90% cumulative distribution particle size) ma kahi o 20 microns.
I ka pōkole, i ka pōʻaiapili o ka hoʻonui wikiwiki ʻana o ka mākeke pākaukau lithium, ka magnesium carbonate ma ke ʻano he mea pākaukau koʻikoʻi, pili pono kona ʻano i ka hana a me ka maikaʻi o nā pā lithium.No laila, i ke koho ʻana i ka magnesium carbonate, pono mākou e koho i kēlā mau huahana me ka ʻike nui paʻa, nā mea haumia haʻahaʻa haʻahaʻa a me ka nui o nā ʻāpana liʻiliʻi e hōʻoia i ka hana kūpono a me ka hoʻohana lōʻihi o nā pā lithium.
