    THERE’S a dirty truth behind supposedly clean electric vehicles (EVs): the lithium batteries they run on can’t be easily recycled.

    Current methods include smelting – which involves high-temperature extraction – or leaching with acids. These processes are energy-intensive, costly and can also produce pollutive substances.

    Many companies have therefore opted not to recycle – globally, only 5 per cent of the world’s lithium batteries are recycled.
