The boss of Stellantis says that the weights of the battery packs used by electric vehicles need to be significantly reduced to make them more environmentally friendly and solve lithium scarcity problems.While recently speaking at the Stellantis’ Freedom of Mobility Forum, the automotive group’s chief executive Carlos Tavares noted that current EVs with a range of approximately 250 miles (400 km) require roughly an extra 500 kg (1,000 lbs) of additional raw materials over conventional internal combustion-powered vehicles. However, Tavares expressed hope that breakthroughs will slash the weight of EV battery packs.Read: Stellantis Lays Off 400 U.S. White-Collar Workers Amidst “Competitive Pressures”“From an environmental standpoint … I don’t think it makes sense [to have such heavy battery packs],” Tavares said, reports Reuters.
