Ma ka lā 16 o Kekemapa, ua hoʻolaha ʻo POSCO e hoʻolilo ʻo ia i ka US $ 830 miliona e kūkulu i kahi mea kanu lithium hydroxide ma Argentina no ka hana ʻana i nā mea pākaukau no nā kaʻa uila.Ua hōʻikeʻia e hoʻomaka ka mea kanu i ka hana i ka hapa mua o 2022, a e hoʻopauʻia a hoʻokomoʻia i loko o ka hana i ka hapa mua o 2024. Ma hope o ka pauʻana, hiki iā ia ke hana i ka 25,000 tons lithium hydroxide i kēlā me kēia makahiki, hiki ke hoʻokō i ka hana makahiki. koi o 600,000 kaʻa uila.
Eia kekahi, ua ʻae ka papa alakaʻi o POSCO i ka lā 10 Dekemaba i kahi hoʻolālā e kūkulu i kahi mea kanu lithium hydroxide me ka hoʻohana ʻana i nā mea maka i mālama ʻia ma ka loko paʻakai ʻo Hombre Muerto ma Argentina.ʻO Lithium hydroxide ka mea kumu no ka hana ʻana i nā cathodes pākaukau.Ke hoʻohālikelike ʻia me nā pākahi lithium carbonate, ʻoi aku ka lōʻihi o ka lawelawe ʻana o nā pākahi lithium hydroxide.I ka pane ʻana i ka piʻi nui ʻana o ka lithium i ka mākeke, i ka makahiki 2018, ua loaʻa iā POSCO nā kuleana mining o ka loko paʻakai ʻo Hombre Muerto mai Australia's Galaxy Resources no US $ 280 miliona.I ka makahiki 2020, ua hōʻoia ʻo POSCO he 13.5 miliona tons lithium ka loko, a ua kūkulu koke a hana i kahi mea kanu hōʻike liʻiliʻi e ka loko.
Ua ʻōlelo ʻo POSCO e hiki ke hoʻonui hou aku i ka mea kanu lithium hydroxide Argentine ma hope o ka pau ʻana o ka papahana a hoʻokomo ʻia i ka hana, no laila e hoʻonui ʻia ka mana hana makahiki o ka mea kanu e kekahi 250,000 tons.
