Lifeless EV Batteries Are Hoarding a Surprising Quantity of Helpful Lithium

The lithium batteries we deem unfit to be used in electrical automobiles may nonetheless include copious quantities of usable, pure lithium we might retrieve and reuse—a probably constant, bountiful provide we’re simply not attempting exhausting sufficient to faucet into, a brand new research suggests.

In a research revealed August 14 within the Journal of Environmental Management, researchers at Edith Cowan College (ECU) in Australia argue that tapping into the leftover lithium in used batteries might gas a practical, sustainable different to lithium mining. Shockingly, the lithium batteries that find yourself in landfills retain practically 80% of their lithium capability—nonetheless very a lot usable. Apart from the clear environmental benefit, recycling lithium batteries might additionally convey a wide selection of socioeconomic advantages, the paper states. 

The paper, a complete overview of the worldwide lithium provide chain, evaluates the efficacy of lithium extraction from mining and recycling. Mining stays the dominant methodology for lithium restoration, however its environmental impression alone ought to be motive sufficient to ultimately transfer away from it, the researchers defined in a statement. Recycling, in contrast, might provide way more bang for our buck. First, recycling processes produce round 61% much less carbon than mining whereas utilizing 83% much less vitality and 79% much less water. 

“By recycling these batteries, you may entry not solely the remaining lithium—which is already purified to close 99 p.c—however it’s also possible to retrieve the nickel and the cobalt from these batteries,” added Asad Ali, research lead creator and a postdoctoral scholar at ECU, within the assertion. Ideally, such recycling amenities wouldn’t be as demanding on the pure surroundings as mining, he stated.

Once more, we’ve got too many idle batteries mendacity round, the researchers famous—and that provide is just anticipated to develop. The worldwide lithium-ion battery market is predicted to develop at an annual charge of 13%, and we’re projected to eat roughly 1,600 kilotons of lithium by 2026. In Australia alone—the place the researchers are primarily based—a government report estimates that lithium battery waste might quantity to 137,000 tons every year. 

With the best investments in infrastructure, tapping into this useful resource might create a brand new, worthwhile area of interest within the vitality sector, stated research co-author Sadia Afrin, additionally a postdoctoral scholar at ECU. However it’s an space that must develop alongside the technological developments of industries that depend on lithium, she added.
