Ku ya 16 Ukuboza, POSCO yatangaje ko izashora miliyoni 830 z'amadolari y'Amerika mu kubaka uruganda rwa lithium hydroxide muri Argentine mu rwego rwo gukora ibikoresho bya bateri z'imodoka zikoresha amashanyarazi. Bivugwa ko uruganda ruzatangira kubakwa mu gice cya mbere cya 2022, kandi ruzarangira rugashyirwa mu bikorwa mu gice cya mbere cya 2024. Nyuma yo kuzura, rushobora gukora toni 25.000 za lithium hydroxide buri mwaka, zishobora guhaza ibyifuzo by'umusaruro w'imodoka zikoresha amashanyarazi 600.000 buri mwaka.
Byongeye kandi, inama y'ubuyobozi ya POSCO yemeje ku ya 10 Ukuboza gahunda yo kubaka uruganda rwa lithium hydroxide hakoreshejwe ibikoresho fatizo bibitswe mu kiyaga cy'umunyu cya Hombre Muerto muri Argentine. Lithium hydroxide ni yo shingiro ry'ibikoresho byo gukora cathodes za bateri. Ugereranyije na bateri za lithium carbonate, bateri za lithium hydroxide zifite ubuzima burambye. Mu rwego rwo gusubiza ubwiyongere bw'ibyifuzo bya lithium ku isoko, mu 2018, POSCO yaguze uburenganzira bwo gucukura ikiyaga cy'umunyu cya Hombre Muerto muri Galaxy Resources yo muri Ositaraliya kuri miliyoni 280 z'amadolari y'Amerika. Mu 2020, POSCO yemeje ko ikiyaga kirimo toni miliyoni 13.5 za lithium, kandi yahise yubaka kandi ikoresha uruganda ruto rw'icyitegererezo iruhande rw'ikiyaga.
POSCO yavuze ko ishobora kongera kwagura uruganda rwa hydroxide ya lithium yo muri Argentine nyuma y’uko umushinga urangiye ugatangira gukora, bityo ubushobozi bw’uruganda mu gukora buri mwaka buziyongeraho andi toni 250.000.
