China: The Epicenter of Electric Vehicle Manufacturing and Battery Recycling
China has solidified its position as the world’s largest market for electric vehicles (EVs), leading both in production and sales. In 2024, the country accounted for over 70% of global electric-car production and more than half of global EV sales. This phenomenal growth isn’t merely due to the escalating demand for greener transportation; it’s also a testament to China’s robust manufacturing capabilities, especially in electric vehicle batteries.
Dominant Players: CATL and BYD
Leading the charge in the EV battery sector are firms like Contemporary Amperex Technology Co. Limited (CATL) and BYD. These companies together command nearly half of the global output of EV batteries, according to the International Energy Agency. As electric vehicles proliferate, these giants are proactively addressing the pressing need for sustainable battery disposal options. They offer various take-back schemes through dealers and 4S stores, allowing customers to trade in their old batteries for discounts when purchasing new vehicles or scrapping old ones.
BYD’s Recycling Initiatives
BYD is not just a player in manufacturing; it also undertakes its own recycling operations. These initiatives process thousands of end-of-life battery packs every year and include partnerships with specialized recycling firms to recover valuable materials from used batteries. BYD’s commitment to sustainability illustrates the company’s foresight in addressing the end-of-life stage of its products.
Geely’s Circular Manufacturing
Another notable player, Geely, has pioneered a “circular manufacturing” system. This system comprises disassembling scrapped vehicles, cascading reuse of power batteries, and achieving high recovery rates for metals. By creating a closed-loop system, Geely is positioning itself as a champion of sustainability in the automotive industry.
CATL’s Comprehensive Recycling System
CATL, recognized as China’s largest EV maker, has developed one of the industry’s most advanced recycling systems through its subsidiary, Brunp. With more than 240 collection depots, Brunp boasts an annual disposal capacity of about 270,000 tons of waste batteries. Remarkably, CATL has achieved recovery rates exceeding 99% for critical materials like nickel, cobalt, and manganese. This high recovery rate not only reinforces CATL’s commitment to environmental stewardship but also ensures a steady supply of materials for new batteries, thus creating a sustainable cycle.

The Importance of Expertise
Alex Li, a battery engineer based in Shanghai, offers valuable insights into this ecosystem. He emphasizes, “No one is better equipped to handle these batteries than the companies that make them.” Their understanding of battery chemistry, the supply chain, and potential uses for recovered materials allows them to create efficient solutions for battery recycling. As he puts it, automakers and battery manufacturers must aim for a fully closed-loop system—one that embraces reuse and recycling entirely.
The Challenges Ahead
Despite these advances, not all EV owners have access to efficient battery recycling solutions. Many smaller manufacturers that once contributed to the vibrant EV landscape are now defunct. Over the past five years, more than 400 smaller EV brands and startups have gone bankrupt due to intense competition and price wars, leaving only about 100 active brands in the market today.
The Impending Battery Wave
Analysts predict that a significant influx of used batteries will hit the market in the coming years. Many EVs purchased under generous subsidies are reaching the end of their life cycles. Li foresees the need for a comprehensive end-of-life system for EV batteries in China, emphasizing the importance of efficient tracing, reuse, and recycling processes at scale. Without such measures, many batteries risk vanishing into the gray market, which poses both environmental and logistical challenges.
Conclusion
China’s extensive infrastructure for electric vehicle manufacturing and battery recycling marks a vital chapter in the global transition towards sustainable transportation. With its key players like CATL and BYD leading the way, the nation is not only focused on producing electric vehicles but also ensuring that the lifecycle of these vehicles contributes positively to both the economy and the environment. As the landscape of the EV sector continues to evolve, China’s proactive approach to sustainability will undoubtedly play a crucial role in shaping the future of electric mobility.
