TL;DR
Japan has developed a new recycling method that can recover up to 90% of lithium from used EV batteries. This breakthrough could significantly impact battery recycling and supply chains, but further testing and commercial deployment are still pending.
Japanese researchers have announced a new recycling method capable of recovering up to 90% of lithium from used electric vehicle (EV) batteries. This development offers a potential solution to the growing challenge of lithium supply and battery waste management, which are critical issues for the global shift toward electric mobility.
The new process was developed by a team at a Japanese research institute, who detailed their method in a recent scientific publication. It involves a chemical treatment that selectively extracts lithium from spent battery cells, significantly increasing recovery efficiency compared to existing techniques.
According to the researchers, this method could be applied to a wide range of used EV batteries, including those from popular lithium-ion models. The process has been tested at a laboratory scale, demonstrating an extraction rate of approximately 90%. The team is now working on scaling the process for industrial application, with pilot projects expected to begin within the next year.
Potential Impact on Battery Recycling and Supply Chains
This breakthrough could dramatically improve the economics of lithium recycling, reducing dependence on mining and lowering environmental impacts. With lithium prices fluctuating and supply concerns mounting, more efficient recovery methods are vital to meet global demand for EV batteries. If commercialized, this technology could also help Japan and other countries strengthen their resource independence and promote sustainable practices across the battery industry.

Growing Need for Efficient Lithium Recycling Solutions
As the global EV market expands rapidly, the volume of used batteries is also increasing. Current recycling methods often recover less than 50% of lithium, and the process can be costly and environmentally taxing. Several countries and companies are investing in advanced recycling technologies, but widespread adoption remains limited. Japan’s new method adds to these efforts by promising higher recovery rates, addressing both resource scarcity and waste management challenges.
Previous research has focused on chemical and thermal treatments, but achieving recovery rates above 80% has been difficult. Japan’s recent development marks a notable advance, with the potential to reshape industry standards if proven scalable.
