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 improve battery sustainability and reduce reliance on raw lithium supplies.
Japan has unveiled a new recycling technique capable of recovering up to 90% of lithium from used electric vehicle batteries, a development that could significantly impact the global battery supply chain and sustainability efforts.
The Japanese research team, led by the New Energy and Industrial Technology Development Organization (NEDO), announced the breakthrough on March 15, 2024. The new method involves a chemical process that efficiently extracts lithium from the cathode materials of spent EV batteries, which are typically difficult to recycle at high recovery rates.
According to NEDO officials, this process not only achieves a lithium recovery rate of up to 90%, but also minimizes environmental impact by reducing the use of hazardous chemicals and lowering energy consumption. The method is currently in pilot testing, with plans for commercial-scale implementation within the next two years.
Industry experts suggest that this innovation could reshape the EV battery recycling landscape, addressing concerns over lithium supply shortages and environmental sustainability.
Potential Impact on Lithium Supply and Battery Recycling
This development is significant because it offers a way to substantially increase the efficiency of lithium recycling, which is essential as global demand for EV batteries continues to grow. Recovering up to 90% of lithium could reduce dependence on mining new lithium, which is environmentally costly and geopolitically sensitive.
Moreover, improved recycling methods could lower the overall cost of EV batteries, making electric vehicles more affordable and accelerating adoption worldwide. Japan’s leadership in this technology positions it as a key player in the sustainable battery supply chain, potentially influencing global standards and practices.

Japan’s Advancements in Battery Recycling Technology
Japan has been investing in battery recycling technologies for several years, aiming to address the increasing volume of used EV batteries and the limited supply of raw materials. Previous efforts focused on chemical leaching and pyrometallurgical processes, but these approaches often resulted in lower recovery rates and higher environmental impacts.
The current breakthrough builds on Japan’s long-standing commitment to sustainable energy and resource management. It follows recent government initiatives to promote circular economy practices in the automotive sector and aligns with global efforts to reduce reliance on imported raw materials for battery production.
Uncertainties About Commercialization and Scale
It is not yet clear when the new recycling process will be available for large-scale commercial use. The pilot phase is ongoing, and there are questions about the cost, scalability, and integration into existing recycling infrastructure. Additionally, the durability and consistency of the process across different battery chemistries remain to be tested.
Next Steps Toward Industry Adoption
The Japanese team plans to finalize pilot testing by late 2024, with hopes to establish commercial facilities by 2026. Industry stakeholders will closely monitor the process’s performance, costs, and environmental benefits during this phase. International collaborations and policy support could accelerate adoption, especially as global demand for EV batteries surges.
