China Lithium Battery Recycling CO2 2026: 95% Efficiency with Water-Only Process

95% efficiency in lithium recovery has been achieved using only water and carbon dioxide, eliminating the need for toxic chemicals. According to the South China Morning Post (SCMP), a Chinese research team has developed a cleaner way to recycle lithium batteries, offering a solution to the environmental toll of traditional recycling methods.

China Lithium Battery Recycling CO2 2026: The 'Three-in-One' Strategy

The team, hailing from the Chinese Academy of Sciences (CAS) and the Beijing Institute of Technology, published their findings in Nature Communications on January 10. Their innovative process employs a "three-in-one" strategy designed to maximize lithium recovery, upgrade transition metals like cobalt and nickel, and sequester carbon to prevent waste by-products.

Traditional recycling often relies on corrosive acids that generate hazardous wastewater. In contrast, this new method operates under ambient conditions without additional leaching agents. The research demonstrated that this clean approach can match the performance of legacy systems, hitting a leaching efficiency of over 95%.

Upcycling Spent Cathodes into Catalysts

A battery's cathode is its positive electrode, typically made from valuable metals. The scientists noted that their method doesn't just recover lithium; it upcycles spent cathode materials into valuable catalysts for other energy technologies. "This approach provides an efficient pathway for lithium recovery while supporting sustainable energy conversion," the team stated. As we enter 2026, this development could significantly lower the carbon footprint of the EV battery lifecycle.
