China’s EV Market Is Booming. There’s Just One Problem

But waste management companies have yet to catch up to the new reality.CommentLoaderSave StorySave this storyCommentLoaderSave StorySave this storyAfter spending the past decade building the world’s largest electric vehicle market, China is confronting one consequence of its success: a growing wave of batteries nearing the end of their service life.Annual sales of battery-powered vehicles in China, including fully electric vehicles and plug-in hybrids, have surged from about 1 million in 2018 to more than 16 million in 2025. With EV batteries typically lasting about eight years, the country is entering its first major wave of battery retirements.The number of batteries requiring disposal or reprocessing is expected to grow rapidly in the years ahead. That poses a major waste-management and recycling challenge for the nation.China reported 400,000 metric tons of EV battery waste last year. A joint study by researchers in China and the United States projected that the figure could grow to 1.69 million metric tons in 2030 and 22.39 million metric tons by 2040.For years, critics of electric vehicles have argued that their environmental benefits are overstated. EVs eliminate tailpipe emissions, but their full life-cycle effects—including the environmental and safety risks posed by discarded lithium-ion batteries—remain a concern. Governments largely chose to accelerate EV adoption anyway, betting that recycling systems would eventually catch up.China began building a recycling system early and has created enough nominal capacity to handle the emerging wave. But much of the country’s used-battery supply continues to flow through uncertified recyclers, which poses serious environmental and safety risks linked to contamination and improper disposal. In a case announced in Jiangxi Province in 2024, an uncertified company was found to have improperly dismantled 364 metric tons of waste lithium iron phosphate batteries. The resulting contamination caused vegetation to die across 6 acres of forest and killed more than 420 cubic feet of standing timber.Although recycling technology has improved, sustaining a profitable battery recycling business remains challenging. Because China leads the world in EV adoption, how Beijing manages both the risks and opportunities of battery retirement could help shape the industry’s global model.China began developing a formal EV battery recycling system as early as 2018. More than 150 companies have since been placed on the government’s certification “white list,” authorizing them to process retired vehicle batteries.By 2023, certified companies had a combined annual processing capacity of 623,000 metric tons, more than 1.5 times the volume of batteries retired that year. Yet they handled only about 25 percent of those batteries, highlighting a gap in recycling efforts.An investigation published earlier this year by Yicai, a Chinese financial news outlet, illustrated the gap between official capacity and actual operations. Its reporters attempted to contact every company on the white list and found that more than 100 were no longer operating or could not be reached.In the paper, “The Urgency to Regulate Informal EV Battery Recycling in China,” researchers described China’s effort to control the informal market as a “losing battle.”“There is poisoning, explosion, and fire caused by improper battery dismantling, waste water being dumped into rivers, contaminants being seeped into groundwater and polluting the soil,” Laixiang Sun, a professor at the University of Maryland and coauthor of the paper, told Inside Climate News.“There is the lithium, copper, and nickel in the batteries,” said Yan Wang, a professor of mechanical engineering at Worcester Polytechnic Institute. “You cannot dump them into the environment.”Yan Wang is also a cofounder of Asc
