A Prediction Model for Recycling Amount of Recycled Metal from Waste Power Battery

Abstract Dependency on importing lithium, nickel and other battery metal resources is increasing. It has an impact on the safety of the supply chain of NEV power batteries. Therefore, ensuring supply of key metal resources is of great necessity to China’s NEV industry. The valuable metals Li, Ni, Co, Mn can be extracted from waste power batteries through recycling, which is conducive to reducing China’s dependence on foreign metal resources. In this paper, a model was established to predict the recycling amount of regenerative metal for power batteries in China. Meanwhile, the influence of regenerative metal on the production and supply of power batteries was analyzed. The results show that the contribution of renewable materials to the supply of Li, Co, Ni and Mn will gradually increase from 4%-7% in 2021 to 19%-54% in 2030 as the number of power batteries decommissioned increases from year to year. Under the background of carbon neutrality, waste power batteries will be used as a reserve of key metal resources, and become an important resource to be seized by major battery manufacturers and vehicle manufacturers.
