ʻO ka mea i hala koke aku nei, ʻo ka Ministry of Industry and Information Technology o Kina (MIIT) he papa helu hou o nā hiʻohiʻona kaʻa uila i manaʻo ʻia, aia i kēia manawa kahi mana o ka Tesla Model 3 me nā ʻokoʻa kobalt-free. ʻOi aku ka maʻalahi, palekana, hiki iā ʻoe ke hana me ka ʻole o nā "mineral koko", akā hoʻonui i ke kaumaha o ka pākaukau a me ka kaʻa i lako.
Ma Kina, manaʻo ʻia e hoʻomaka ana ka hoʻopuka ʻana i ka mana pākaukau cobalt-free o ka Tesla Model 3 mai ka waena o Iulai a ʻAukake. Mea hoʻolako pākahiko , ʻo ia ka hui Kina Modern Amperex Technology, i ʻike ʻia ma ka honua holoʻokoʻa ʻo CATL. ʻO Tesla Model 3 ke kaumaha paona me nā ʻaniani kobalt-free 1745 kg, aʻo ke kaumaha o ke kumu hoʻohālike ma LG Chem NCM811 nickel-manganese-cobalt batteries he 1614 kg.
ʻO ka ʻōlelo hoʻohewa nui o nā pākahiko cobalt ʻo ia ka hoʻohana ʻia ʻana o ka hana keiki no ka unuhi ʻana mai ia mai nā mines ma ka Democratic Republic of Congo, kahi e ʻeli nui ʻia ai ka cobalt. Pono ʻoe e hoʻomanaʻo i ka palena o nā lako cobalt ma ka Honua a paʻakikī paha nā lako. No laila, koi ʻia ka ʻoihana e ʻimi i kahi ʻano ʻē aʻe i ka cobalt, ʻoiai ʻoi aku ka haʻahaʻa o ka ikehu o nā pila me ka ʻole o ka cobalt. No ka loaʻa ʻana o ka parity me nā ʻeke NCM, pono e hoʻonui a kaumaha nā ʻāpana kobalt-free, a he ala pololei kēia i ka pae hoʻemi.
ʻO ka mea maʻamau, hoʻohana ʻia nā pahu pahu cobalt-free i ke ʻano o ka lithium iron phosphate (LFP) i nā kaʻa kaʻa a me nā kaʻa kalepa, ʻoiai nā kaʻa kaʻa e hoʻohana i nā pihi i hana ʻia me ka nickel, cobalt a me ka manganese. Mai Tesla, hiki iā mākou ke manaʻo ʻo ka hoʻonui ʻana i nā pihi ʻo ia wale nō ka mōhai a ka hui e hana ai, a ʻaʻole e emi ka laulā o ke kumu hoʻohālike. Eia naʻe, hiki ke hāʻawi ʻia nā hiʻohiʻona me nā pihi me ka cobalt i nā kumukūʻai ʻoi aku ka maikaʻi. E kali kākou no ka hoʻomaka ʻana o ke kūʻai.
