A growing number of global automakers and battery companies are entering the solid-state battery market South Korea’s Lotte Chemical Corp. is advancing into the electric vehicle battery market by forming a $200 million joint venture with US battery startup Soelect Inc.The petrochemical unit of Lotte Group, Korea’s fifth-largest conglomerate, on Tuesday signed a memorandum of understanding with Soelect to manufacture advanced battery components for electric vehicles in the US.With the $200 million investment in the JV, the two companies aim to scale up production of Soelect’s lithium metal anodes for next-generation batteries with higher energy density and fast-charging capabilities.Based in Greensboro, North Carolina, Soelect is currently producing lithium metal anodes for next-generation solid-state batteries on a pilot basis.Soelect and Lotte Chemical plan to mass produce such advanced batteries from 2025 when solid-state batteries are expected to be widely adopted by EV makers.
