Sweden-based Northvolt is looking to develop the world's "greenest" battery by recycling old batteries, stripping out the waste, and reusing the rare earth metals that help to generate energy.
Demand for lithium batteries has surged since the advent of electric vehicles, which had a record-breaking year in 2022, accounting for 12.1% of the total market share for new cars in Europe. Going electric has long been touted as a key fix to the climate crisis, but batteries' start and end of life pose a big, dirty problem — something Northvolt wants to solve.
