Ma ka lā 16 o Kēkēmapa, ua hoʻolaha ʻo POSCO e hoʻokomo kālā ana i US$830 miliona e kūkulu i kahi hale hana lithium hydroxide ma Argentina no ka hana ʻana i nā mea pila no nā kaʻa uila. Ua hōʻike ʻia e hoʻomaka ke kūkulu ʻana o ka hale hana i ka hapa mua o 2022, a e hoʻopau ʻia a hoʻokomo ʻia i ka hana i ka hapa mua o 2024. Ma hope o ka hoʻopau ʻana, hiki iā ia ke hana i 25,000 tons o ka lithium hydroxide i kēlā me kēia makahiki, kahi e hiki ai ke hoʻokō i ke koi hana makahiki o 600,000 mau kaʻa uila.
Eia kekahi, ua ʻāpono ka papa alakaʻi o POSCO ma Dekemaba 10 i kahi hoʻolālā e kūkulu i kahi hale hana lithium hydroxide me ka hoʻohana ʻana i nā mea maka i mālama ʻia ma ka loko paʻakai ʻo Hombre Muerto ma Argentina. ʻO ka lithium hydroxide ka mea nui no ka hana ʻana i nā cathodes pākahiko. Ke hoʻohālikelike ʻia me nā pila lithium carbonate, ʻoi aku ka lōʻihi o ke ola lawelawe o nā pila lithium hydroxide. I ka pane ʻana i ka ulu ʻana o ke koi no ka lithium ma ka mākeke, i ka makahiki 2018, ua loaʻa iā POSCO nā kuleana mining o ka loko paʻakai ʻo Hombre Muerto mai nā Galaxy Resources o Australia no US$280 miliona. I ka makahiki 2020, ua hōʻoia ʻo POSCO aia i loko o ka loko he 13.5 miliona tons o ka lithium, a ua kūkulu koke a hoʻokele i kahi hale hana hōʻikeʻike liʻiliʻi ma ka loko.
Ua ʻōlelo ʻo POSCO e hoʻonui hou aku paha ia i ka hale hana lithium hydroxide Argentine ma hope o ka pau ʻana o ka papahana a hoʻokomo ʻia i ka hana, i hiki ai ke hoʻonui ʻia ka mana hana makahiki o ka hale hana e 250,000 tons hou aʻe.
