Ua hoʻomaka ka hui i ka hoʻololi ʻana i nā hiʻohiʻona maʻamau i LFP chemistry e pōmaikaʻi mai kā lākou ʻike palekana palekana, lōʻihi ke ola pōʻai, a hoʻemi i ka hilinaʻi ʻana i nā mea liʻiliʻi e like me ka cobalt a me ka nickel. ʻO kēia hoʻololi hoʻolālā e hiki ai iā Tesla ke hōʻemi i nā kumukūʻai pākaukau i ka wā e hāʻawi ana i nā kaʻa me ka lōʻihi o ka lōʻihi, ʻoiai ka haʻahaʻa haʻahaʻa haʻahaʻa o ka ikehu i hoʻohālikelike ʻia i kā lākou mau pā uila NCA kuʻuna.
A: Ke kuhi hewa nei kēia hoʻohālikelike i ka pilina — hoʻohana maoli ʻia nā pākaukau LFP i kekahi mau kaʻa Tesla. Hoʻohana ʻo Tesla i nā kemika pākaukau like ʻole ma kā lākou lineup, me LFP (LiFePO4) a me NCA (Nickel Cobalt Aluminum). ʻO nā hiʻohiʻona Tesla i hoʻolako ʻia e LFP hiki ke hāʻawi i ka lōʻihi o ka lōʻihi o ka pākaukau a me nā kumukūʻai hoʻololi haʻahaʻa i hoʻohālikelike ʻia i nā hiʻohiʻona i hoʻolako ʻia e NCA, ʻoiai me ka liʻiliʻi liʻiliʻi. ʻO ka koho maikaʻi e pili ana i kāu mau mea nui: LFP no ka lōʻihi a me ke kumu kūʻai haʻahaʻa, NCA no ka palena kiʻekiʻe.
