China's rapid increase in electric vehicle (EV) sales has led to a surge in spent batteries, with nearly 400,000 tonnes generated last year and projected to rise to one million tonnes per year by 2030. To address this waste issue, the Chinese government has launched new policies mandating end-of-life recycling for EVs and their batteries, with manufacturers responsible for recycling. This strategy not only addresses the waste problem but also aims to secure critical minerals like lithium, cobalt, nickel, and manganese. Chinese companies like CATL's Brunp subsidiary and Botree are leading the way in battery recycling, offering higher prices to EV owners and expanding into foreign markets to meet demand.
