TL;DR
Japanese scientists have created a new recycling method capable of extracting up to 90% of lithium from used EV batteries. This breakthrough could significantly improve battery recycling efficiency and sustainability.
Japanese researchers have announced a new recycling method that can recover up to 90% of lithium from used electric vehicle (EV) batteries, marking a significant advancement in battery recycling technology. This development aims to address the growing demand for lithium and reduce environmental impacts associated with battery disposal.
The new process was developed by scientists at a leading Japanese research institute, with the breakthrough publicly disclosed in March 2024. According to the institute, the method involves a novel chemical treatment that efficiently extracts lithium from spent batteries, minimizing waste and energy use. The process has undergone laboratory testing, demonstrating a lithium recovery rate of approximately 90%, which is higher than current commercial recycling methods.
Officials from the research team stated that the method is scalable and could be integrated into existing recycling facilities. The process also aims to recover other valuable materials, such as cobalt and nickel, from used batteries, further enhancing its economic viability. The development comes amid rising global demand for lithium, driven by the proliferation of electric vehicles and renewable energy storage systems.
Potential Impact on Battery Recycling Industry
This breakthrough could significantly improve the efficiency and sustainability of lithium recycling, reducing reliance on mining and lowering environmental impacts. It may also influence global recycling standards and encourage other countries to develop similar technologies, helping to meet the increasing demand for EV batteries while minimizing ecological footprints.

Japan’s Growing Focus on Sustainable Battery Recycling
Japan has been actively investing in sustainable battery technologies, aiming to become a leader in EV supply chain sustainability. The country’s automotive industry, including companies like Toyota and Nissan, has committed to expanding EV production, which amplifies the need for effective recycling solutions. Prior efforts have focused on developing chemical and mechanical recycling methods, but none have achieved such high recovery rates as this new process.
The development aligns with Japan’s broader environmental goals and international commitments to reduce carbon emissions. Globally, the demand for lithium has surged, with supply concerns prompting governments and industries to prioritize recycling innovations. The new method represents a step forward in addressing these challenges.
“Our new chemical process can recover up to 90% of lithium from used batteries, which is a significant improvement over existing methods.”
— Dr. Hiroshi Takeda, lead researcher at the Japanese institute
Uncertainties About Commercial Implementation
It is not yet clear when the new recycling method will be commercially available or how cost-effective it will be at scale. Researchers are still evaluating the process’s long-term durability and potential environmental impacts during large-scale deployment. Additionally, regulatory approvals and industry adoption timelines remain uncertain.
Next Steps Toward Industry Adoption
The research team plans to pilot the process in a pilot recycling facility later this year. If successful, they aim to collaborate with industry partners to scale up production and conduct economic feasibility studies. Further testing will also focus on integrating the method into existing recycling infrastructure and ensuring compliance with environmental standards.
