E hoʻohana ʻo Tesla i nā pūnaewele LiFePO4 ma Kina ma kahi o nā pūnaewele kobalt?
Nuhou hoihoi mai ka Hikina mamao. Ua ʻōlelo ʻo Reuters aia ʻo Tesla i ke kamaʻilio mua ʻana me ka mea hoʻolako uila ʻo LiFePO4 (Lithium Iron Phosphate, LFP). Hāʻawi lākou i kahi haʻahaʻa haʻahaʻa haʻahaʻa ma mua o nā ʻāpana lithium-ion i hoʻokumu ʻia i ka cobalt, akā ʻoi aku ka liʻiliʻi loa.
E hōʻoiaʻiʻo anei ʻo Tesla i ka honua e hoʻohana i nā cell LFP?
LFP (LiFePO4) ʻaʻole hiki ke hoʻopau i nā kaʻa no ka mea hiki iā lākou ke mālama i ka ikehu liʻiliʻi no ka paona like. ʻO ia hoʻi, ʻo ka hoʻāʻo ʻana e mālama i ka mana pākaukau i koho ʻia (e laʻa me 100 kWh) pono ka hoʻohana ʻana i nā pūʻolo pākahi nui a kaumaha. A he pilikia paha kēia i ka lele ʻana o ke kaʻa i 2 tons i ke kaumaha a kokoke i 2,5 tons ...
> ʻO Samsung SDI me ka pākaukau lithium-ion: i kēia lā graphite, silikoni koke, liʻiliʻi liʻiliʻi me nā metala liʻiliʻi a me kahi ākea o 360-420 km i ka BMW i3
Eia naʻe, e like me Reuters, ke kamaʻilio nei ʻo Tesla me CATL e hoʻolako i nā cell LiFePO.4... Pono lākou e ʻoi aku ka liʻiliʻi "e nā ʻumi o ka pakeneka" ma mua o nā "mea maoli". ʻAʻole i hōʻike ʻia inā i manaʻo ʻia nā cell NCA e hoʻohana ai ʻo Tesla a puni ka honua "i kēia manawa" a i ʻole ka ʻano NCM makemake (a ke hoʻohana nei?) Ma Kina.
ʻO NCA nā pūnaewele cathode nickel-cobalt-aluminum a ʻo NCM nā pūnana cathode nickel-cobalt-manganese.
LiFePO pūnaewele4 Loaʻa iā lākou kēia mau hemahema, akā he mau mea maikaʻi nō hoʻi lākou: ʻoi aku ka ʻoi aku o ko lākou kahe hoʻokuʻu ʻana (ʻoi aku ka liʻiliʻi o ka voltage i ka wā o ka hana), kū lākou i nā pōʻai hoʻoiho a ʻoi aku ka palekana ma mua o nā cell lithium-ion ʻē aʻe. He mea paʻakikī hoʻi e hoʻomāhuahua i ka ʻoiaʻiʻo ʻaʻole lākou e hoʻohana i ka cobalt, he mea kūʻai nui a hoʻopaʻapaʻa mau ʻia ma muli o ka wahi o kāna waihona a me nā keiki i maʻa i ka hana ʻana i nā mines.
