Not all electric-vehicle batteries are hitting the scrap heap when they're done in cars. Come the end of the road, when the lithium-ion battery can no longer provide the driving range and acceleration required to power a vehicle, it still holds up to 80 per cent of its storage capability.
In 2017, when worldwide sales of electric vehicles exceeded one million cars per year for the first time, calculations from UK-based University of Birmingham researchers revealed stark figures. These vehicles alone are destined to leave some 250,000 tonnes of unprocessed battery waste when they eventually reach the scrap heap in 2027.
In a similar vein, German start-up Duesenfeld shreds batteries under inert nitrogen, with the flammable electrolyte being pumped out, evaporated and condensed. Dry materials are then separated by operators based on size, weight, magnetism and electric conductivity.
For example, electronic waste recycler TES has opened two new battery-recycling facilities in Singapore and France that recover elements using mechanical and hydro-metallurgical methods. Each site uses auto-punching machines and shredders to break batteries down into fine substances, while in a solution.
