Battery recycling could help make electric vehicle production more sustainable

The humble battery is having a moment, as countries around the world turn their attention to electric vehicles (EVs) to cut carbon emissions from transportation.
The key to transitioning from gasoline-powered cars to electric hinges on efficient, long-lasting batteries. But the production of batteries depends on the (finite) supply of a bunch of key minerals like lithium and cobalt, which is already leading to a scramble by major world powers and corporations to secure these resources.
Most of the world's supply of lithium comes from just four countries: Australia, Chile, China and Argentina. The supply of cobalt is even more concentrated, with 70 per cent of it coming from the Democratic Republic of Congo alone.
That makes it important to secure another source of these minerals — by recycling old batteries.
"The more EVs that are bought and put through the recycling process, the more we can offset, in the future, raw materials from the ground and have a more sustainable source for the raw materials," said Kunal Phalpher, chief strategy officer at battery recycling company Li-Cycle.
Li-Cycle, which is based in Toronto, is building a "hub and spoke" system to deal with old batteries. Phalpher said that transporting heavy EV batteries can be expensive and tricky. The company's spokes are smaller facilities that would be closer to where the batteries are coming from, thereby cutting down on transportation costs.
Batteries (like the one from a Chevy Bolt seen in the photo above) are shredded into a "black mass" in the Li-Cycle's spoke facilities, then sent to a central hub facility that processes it into useful minerals like cobalt, nickel and lithium that can be reused in batteries and other products.
The company operates spoke facilities in Kingston, Ont., and Rochester, N.Y., with more on the way. It's building its first hub facility in Rochester.
Phalpher said Li-Cycle can recover up to 95 per cent of the materials in old batteries.
EV batteries last about 10 years. Phalpher said he expects a large number of EV batteries in Ontario to start reaching the end of their lifecycle by 2030.
Nikki Skuce, who co-authored a report with the Pembina Institute last year about EV battery recycling policy in British Columbia, says the federal and provincial governments need to formulate an action plan for used batteries.
"I think it's great to see all of these incentives and targets for electric vehicles," Skuce said. "But we also really need to look at the whole life cycle and be investing now in that recycling capacity."
