Ngomhla we-16 kweyoMnga, iPOSCO yabhengeza ukuba iza kutyala imali eyi-US $830 yezigidi ukwakha isityalo se-lithium hydroxide eArgentina ukuze kuveliswe izixhobo zebhetri zezithuthi zombane. Kubikwa ukuba isityalo siza kuqala ukwakhiwa kwisiqingatha sokuqala sowama-2022, kwaye siza kugqitywa size sisetyenziswe kwisiqingatha sokuqala sowama-2024. Emva kokuba sigqityiwe, singavelisa iitoni ezingama-25,000 ze-lithium hydroxide ngonyaka, ezinokuhlangabezana neemfuno zonyaka zemveliso yezithuthi zombane ezingama-600,000.
Ukongeza, ibhodi yabalawuli bePOSCO yavuma nge-10 kaDisemba isicwangciso sokwakha isityalo se-lithium hydroxide kusetyenziswa izinto eziluhlaza ezigcinwe kwichibi letyuwa laseHombre Muerto eArgentina. I-lithium hydroxide yeyona nto iphambili yokwenza ii-cathodes zebhetri. Xa kuthelekiswa neebhetri ze-lithium carbonate, iibhetri ze-lithium hydroxide zinobomi obude benkonzo. Ukuphendula imfuno ekhulayo ye-lithium kwimarike, ngo-2018, i-POSCO yafumana amalungelo okumba ichibi letyuwa laseHombre Muerto kwiGalaxy Resources yase-Australia nge-US$280 yezigidi. Ngo-2020, i-POSCO yaqinisekisa ukuba ichibi liqulethe iitoni ezili-13.5 zezigidi ze-lithium, kwaye ngoko nangoko yakha yaza yaqhuba isityalo esincinci sokubonisa ecaleni kwechibi.
I-POSCO ithe inokwandisa ngakumbi isityalo saseArgentina se-lithium hydroxide emva kokuba iprojekthi igqityiwe kwaye iqalisiwe ukusebenza, ukuze amandla okuvelisa ngonyaka wesityalo ande ngezinye iitoni ezingama-250,000.
