TL;DR
Japan has developed a new method to recover up to 90% of lithium from used EV batteries. This breakthrough could significantly improve battery recycling efficiency and reduce reliance on raw lithium mining.
Japan has announced a new recycling method capable of recovering up to 90% of lithium from used electric vehicle (EV) batteries, a significant advance in battery recycling technology. This development is expected to impact global efforts to improve sustainability in the EV supply chain and reduce dependence on primary lithium sources.
The Japanese research team, led by scientists from the National Institute of Advanced Industrial Science and Technology (AIST), unveiled a process that efficiently extracts lithium from spent EV batteries. The method involves a novel chemical treatment that selectively dissolves lithium compounds, achieving recovery rates of up to 90%, according to official statements. This process is described as more environmentally friendly and cost-effective compared to existing recycling techniques.
Japan’s Ministry of Economy, Trade and Industry (METI) highlighted that the new method could be commercially viable within the next two years, with pilot programs already underway. Industry experts suggest that such a high recovery rate could significantly reduce the need for new lithium mining, which is often associated with environmental concerns and geopolitical risks.
Potential Impact on Global Lithium Recycling and Supply Chains
This breakthrough could transform how lithium is recycled worldwide, making EV battery reuse more sustainable and economically viable. By recovering up to 90% of lithium, Japan’s method addresses a key challenge in battery recycling — low recovery efficiency — and could lessen the industry’s environmental footprint. It also offers a pathway to reduce reliance on imported raw lithium, which is subject to geopolitical tensions and supply chain disruptions.
For automakers and battery manufacturers, this development could lower costs and improve environmental credentials, supporting the broader adoption of electric vehicles. Environmental groups and policymakers may view this as a positive step toward a circular economy in the EV sector.

Japan’s Advances in Battery Recycling and Lithium Sustainability
Japan has been actively investing in battery recycling technologies amid rising demand for EVs and concerns over lithium resource depletion. Prior efforts focused on chemical and mechanical recycling methods, but recovery rates typically ranged between 50% and 70%. The new technique, announced in March 2024, represents a significant improvement in lithium recovery efficiency. Japan’s government has set ambitious targets to promote sustainable battery lifecycle management, aligning with global efforts to reduce carbon emissions and environmental impact.
This development follows recent global initiatives to enhance recycling infrastructure, but Japan’s method stands out for its high recovery rate and potential scalability. Industry analysts see this as part of a broader push toward a circular economy in the EV supply chain.
“This innovation aligns with Japan’s goal to lead in environmentally sustainable battery technologies and reduce reliance on imported lithium.”
