POSCO Group announced on August 19 that it will cooperate with Chinese cathode materials producer Longbai Group across the secondary battery materials value chain, including battery-grade lithium supply and used battery recycling.

POSCO Holdings signed a strategic MOU with Longbai Group at POSCO Center in Seoul. Under the agreement, POSCO Group will seek to supply battery-grade lithium produced in South Korea and overseas to Longbai Group.

Potential supply sources include lithium produced from Australian ore by POSCO Pilbara Lithium Solution in Yulchon Industrial Complex, brine-based lithium from POSCO Argentina, and lithium recovered from used batteries by POSCO HY Clean Metal.

POSCO Pilbara Lithium Solution plans to complete Longbai Group’s quality certification process for its ore-based battery-grade lithium hydroxide by the fourth quarter of this year. Once certification is completed, the two sides will discuss potential mass-production supply.
