TL;DR
Japan has developed a new method to recover up to 90% of lithium from used EV batteries. This breakthrough could significantly improve recycling efficiency and reduce reliance on raw lithium. The development is confirmed, but commercial application details are still emerging.
Japan has developed a novel recycling method capable of recovering up to 90% of lithium from used electric vehicle (EV) batteries, according to official sources. This breakthrough has the potential to dramatically improve the efficiency of battery recycling and reduce dependence on newly mined lithium, a critical component for EV production. The development is confirmed by Japan’s Ministry of Economy, Trade and Industry (METI) and research institutions involved in the project.
The new recycling process was announced by Japan’s Ministry of Economy, Trade and Industry (METI) on March 15, 2024. It uses an innovative chemical treatment that selectively extracts lithium from spent EV batteries, which are increasingly accumulating due to the rapid growth of electric vehicle adoption worldwide. The method reportedly achieves an efficiency of up to 90% in lithium recovery, surpassing existing recycling techniques.
Researchers from Japan’s National Institute of Advanced Industrial Science and Technology (AIST) led the development, collaborating with several industry partners. The process involves a combination of thermal pretreatment and a specialized solvent extraction step, designed to maximize lithium recovery while minimizing environmental impact. Officials indicate that the technique could be scaled for commercial use within the next few years, though specific timelines have not been confirmed.
Potential Impact on Global Lithium Recycling Efforts
This development could significantly influence the global supply chain for lithium, a key material in EV batteries. By increasing recovery rates to 90%, Japan’s method addresses concerns about resource scarcity and environmental impact associated with lithium mining. It may also lower costs for manufacturers and promote more sustainable recycling practices worldwide, especially as EV adoption accelerates.

Japan’s Advancements in Battery Recycling Technology
Japan has long been a leader in battery technology and recycling innovation. Prior efforts focused on improving the efficiency of existing processes, but recent shortages of lithium and environmental concerns have driven research into more effective recycling methods. The new technique builds on previous studies but achieves a notably higher recovery rate, positioning Japan at the forefront of sustainable EV battery management.
The global EV market has seen exponential growth over the past five years, leading to an increasing accumulation of used batteries. Current recycling methods typically recover less than 70% of lithium, with environmental and economic limitations. Japan’s recent breakthrough aims to change that landscape, aligning with broader goals of resource sustainability and circular economy principles.
“This innovation aligns with Japan’s commitment to sustainable resource management and could reduce reliance on imported lithium in the future.”
