Seoul: South Korean battery maker LG Energy Solution Ltd said on Tuesday that it would spend $2.1 billion together with General Motors (GM) to build another electric vehicle (EV) battery factory in America. LGES and GM are expected to chip in half of the amount each through their US-based joint venture, Ultium Cells LLC, for what will be their third joint battery plant in America, a regulatory filing by LG Chem Ltd, LGES' parent company, showed. The investment will be made in installments through 2026, the filing read. LGES declined to provide details, such as the location or size, until the formal announcement. The two companies are expected to hold an event soon to unveil the investment in detail, reports Yonhap news agency. It had been widely expected that Ultium Cells is looking at Michigan as the site for the third battery plant.
