Millions of electric cars are coming. What happens to all the dead batteries?
https://www.sciencemag.org/news/2021/05/millions-electric-cars-are-coming-what-happens-all-dead-batteries...Governments are inching toward requiring some level of recycling. In 2018, China imposed new rules aimed at promoting the reuse of EV battery components. The European Union is expected to finalize its first requirements this year. In the United States, the federal government has yet to advance recycling mandates, but several states, including California—the nation’s largest car market—are exploring setting their own rules....
...Better recycling methods would not only prevent pollution, researchers note, but also help governments boost their economic and national security by increasing supplies of key battery metals that are controlled by one or a few nations. “On the one side, [disposing of EV batteries] is a waste management problem. And on the other side, it’s an opportunity for producing a sustainable secondary stream of critical materials,” says Gavin Harper, a University of Birmingham researcher who studies EV policy issues.
To jump-start recycling, governments and industry are putting money into an array of research initiatives. The U.S. Department of Energy (DOE) has pumped some $15 million into a ReCell Center to coordinate studies by scientists in academia, industry, and at government laboratories. The United Kingdom has backed the ReLiB project, a multi-institution effort. As the EV industry ramps up, the need for progress is becoming urgent, says Linda Gaines, who works on battery recycling at DOE’s Argonne National Laboratory. “The sooner we can get everything moving,” she says, “the better.”...
