Recycling could become the dominant source of key materials for electric-vehicle components in China over the coming decades, new research said.
This shift is critical because finite raw material resources threaten the long-term sustainability of the electric-vehicle (EV) manufacturing boom. As the industry expands, relying solely on newly mined minerals may become physically or economically impossible.
Xin Xiong, a professor at Nanjing University, led the study examining how the circular economy can support the automotive sector. The findings suggest that the recovery of materials from end-of-life vehicles will eventually outweigh the extraction of virgin minerals to meet production demands [1].
China currently holds a massive lead in the global supply chain. The country accounts for more than 70% of global EV battery production [2]. This scale provides a significant advantage in establishing the infrastructure needed to collect and process spent batteries at a national level.
Integrating recycled materials into the manufacturing loop reduces the environmental impact of mining, and mitigates the risks associated with volatile commodity prices. The study said that the transition to a recycling-dominant model is a logical evolution for a market facing resource scarcity [1].
While the transition will take decades to fully realize, the groundwork involves developing more efficient chemical and mechanical processes to extract high-purity metals from old cells. These efforts aim to ensure that the growth of the EV fleet does not outpace the availability of the minerals required to build them [1].
“Recycling could become the dominant source of key materials for electric-vehicle components in China.”
China's move toward a circular battery economy aims to decouple industrial growth from mineral extraction. By leveraging its current dominance in battery production, China is positioning itself to reduce dependence on volatile global mining markets and create a self-sustaining loop of materials that secures its automotive supply chain against future shortages.
