As battery demand grows, recycling needs to capture more of the valuable resources in each cell

Global demand for batteries is surging. Lithium-ion cells are being incorporated into ever-wider areas of consumer and industrial life, but one of the biggest drivers of battery demand is the accelerating transition to electric vehicles (EVs). EV numbers are predicted to rise by 36% per year globally, passing 245 million vehicles by 2030.

The lithium-ion batteries that power a typical EV might contain around 29kg of nickel, 8kg of cobalt and 6kg of lithium. Meanwhile, dumping expired batteries can contaminate the environment with toxic compounds, or cause them to degrade, self-ignite and start fires in landfills. An obvious answer is to recycle batteries for their valuable materials, and create a more circular battery economy.
