Opel parent company Stellantis and Chinese battery manufacturer CATL are planning to build a billion-euro mega-factory in Zaragoza, Spain. Together, they will invest €4.1 billion in a plant for the production of lithium iron phosphate (LFP) cells for electric vehicles, as the companies announced on Tuesday. To this end, they have founded a joint venture in which each holds a 50 percent stake. The capacity of the plant could reach 50 gigawatts. However, further planning is dependent on the development of the market in Europe and the support of the European and Spanish authorities. Production is scheduled to start at the end of 2026. The battery plant is to be CO2-neutral.
