Audi AG aims to use solid-state batteries for future high-powered electric sports cars, possibly starting with an all-electric supercar.
High-performance EVs need significantly better batteries than today’s lithium-ion units, Peter Oberndorfer, who heads Audi's product and technology communications, tells Motoring. He says even next-generation lithium-ion batteries aren’t likely to suffice for future EV demands.
While traditional lithium-ion technology continues to be refined, the “real progress” will come from solid-state and other advanced batteries, Oberndorfer says. He points to the potential for improved energy density that can extend a vehicle’s driving range and shorten recharging times.
No time frame was given for the program. But Motoring and other media reports speculate that Audi has revived the development of an electric supercar to compete against the next-generation Tesla Roadster and Rimac Concept One EVs. Other carmakers don’t expect solid-state batteries to be ready for mass production for about a decade.
Audi’s first wave of EVs, which will be marketed under the company’s e-tron sub-brand, will use lithium-ion packs. The rollout starts this year with a crossover/SUV. A sportback model and sedan also are in the works.
