POSCO Future M, the battery materials unit of POSCO Holdings, said Monday it has secured a 1 trillion-won ($668 million) contract to supply battery materials to a global automaker. Under the five-year agreement, POSCO Future M will supply synthetic graphite anode active materials to the undisclosed carmaker from 2027 through 2032, the company said in a press release. To fulfill the contract, the company plans to invest 357 billion won to build a synthetic graphite anode plant in Vietnam. In October, POSCO Future M signed a separate 670 billion-won deal with the same automaker to supply natural graphite anodes. The company said it plans to expand the partnership to include lithium and cathode materials. POSCO Future M currently produces cathode materials for nickel-cobalt-manganese (NCM) and nickel-cobalt-manganese-aluminum (NCMA) batteries. It plans to expand its portfolio to include lithium iron phosphate (LFP), all-solid-state batteries (ASBs) and lithium manganese-rich (LMR) batteries. Backed by its advanced technology and expanded production capacity, the company said it is "in talks"
