by Prospects of Solid-State Batteries in Electric Vehicles
Solid-state batteries are considered a promising technology for electric vehicles because they can provide a range of over 600 miles on a single charge. Major automakers such as Nissan and Toyota plan to launch them into mass production within a few years. However, technological challenges and delays may affect these plans.
Companies including BMW, Mercedes-Benz, and Stellantis continue to invest in the development of solid-state batteries. BMW is already testing an i7 prototype with such batteries from the American company Solid Power. Mercedes is also experimenting with similar technology, which, according to developers, can increase energy density by 25%.
“These advantages not only increase the range but also influence the car’s design, for example, its architecture. Solid-state batteries are also less prone to overheating,” noted the head of Mercedes’ battery development department, Uwe Keller.
Stellantis calls solid-state batteries the “North Star” in the battery field because they allow manufacturers to choose between greater range or fewer materials. Toyota and Nissan also aim to commercialize this technology by the end of the decade, although timelines may change.
Despite the optimism of automakers, mass production of solid-state batteries is likely to begin no earlier than the 2030s. Technological difficulties, such as material stability and production cost, remain the main obstacles. Meanwhile, traditional lithium-ion batteries continue to dominate the market, improving their efficiency.
