The Chinese behemoth that makes electric-car batteries for Tesla Inc. and Volkswagen AG developed a power pack that lasts more than a million miles — an industry landmark and a potential boon for automakers trying to sway drivers to their EV models. Contemporary Amperex Technology Co. Ltd. is ready to produce a battery that lasts 16 years and 2 million kilometers (1.24 million miles), Chairman Zeng Yuqun said in an interview at company headquarters in Ningde, southeastern China. Warranties on batteries currently used in electric cars cover about 150,000 miles or eight years, according to BloombergNEF.

Extending that lifespan is viewed as a key advance because the pack could be reused in a second vehicle. That would lower the expense of owning an electric vehicle, a positive for an industry that’s seeking to recover sales momentum lost to the coronavirus outbreak and the slumping oil prices that made gas guzzlers more competitive.

“If someone places an order, we are ready to produce,” said Zeng, 52, without disclosing if contracts for the long-distance product have been signed. It would cost about 10% more than the batteries now inside EVs, said Zeng, whose company is the world’s largest maker of the batteries.

Anticipating a rapid return to growth for the EV industry, CATL is plowing research-and-development dollars into advances in battery technology. While the coronavirus outbreak will drag down sales throughout this year, EV demand will pick up in early 2021, said Zeng, who founded CATL a decade ago.
