Electric vehicles have a dirty secret. The race is on to clean it up

The rollout of electrical autos is fixing one environmental downside and creating one other one, however options are on the horizon

New advances in recycling are offering an answer to the environmental harm brought on by skyrocketing demand for lithium-ion (Li-ion) batteries.

A booming marketplace for EVs has prompted a scramble for lithium, nickel, cobalt and different minerals used to make the batteries that energy them.

The soiled enterprise of lithium mining has been mired in controversy, with accusations of poisoned rivers in Tibet and Argentina and water shortages in Chile, whereas cobalt extraction within the Democratic Republic of Congo has been linked to modern-day slavery.

Recycling Li-ion batteries, that are usually extra advanced and might even explode if not handled with care, has proved prohibitively costly, with some estimates placing the worldwide recycling charge at simply 5 per cent.

Nevertheless, a rising variety of recycling firms are attempting to shut the loop on Li-ion cells and spare them from landfill, drawing on developments in hydrometallurgy, the place supplies in batteries are dissolved and separated in acids and solvents.

Within the US, former Tesla chief technical officer Jeffrey Brian Strausel arrange Nevada-based Redwood Materials (pictured under) and hopes to make sufficient recycled supplies for 5m EV batteries by 2025.

The agency has gained the backing of the US Division of Power within the type of a $2bn (£1.7bn) mortgage, and is partnering with Audi, Volkswagen and Toyota to recycle their EV batteries.

“Redwood’s mission is to create a round provide chain for electrical autos that makes them extra sustainable and drives down the only costliest part: batteries,” stated a spokesperson for the corporate. “Ramping up a home battery supplies provide chain is the easiest way we are able to meet the US’s 2030 electrification targets.” 

In Canada, Li-cycle has 4 crops recycling 30,000 tonnes of batteries a yr, with plans for one more three websites within the pipeline.

In the meantime within the UK, the place Li-ion EV batteries need to be despatched abroad for processing, Altilitech, a inexperienced expertise firm aiming to decarbonise the EV provide chain, is bidding to open a first-of-its-kind recycling centre. The agency has been awarded £3m of presidency funding and hopes to be operational at a brand new website in Teesside by 2025.
