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 supply chains and environmental sustainability.
Japan has unveiled a new recycling method capable of recovering up to 90% of lithium from used electric vehicle batteries, a development that could greatly reduce reliance on raw lithium extraction and address environmental concerns. The innovation was announced by Japan’s Ministry of Economy, Trade and Industry (METI) on March 15, 2024, and is expected to influence global battery recycling practices.
The new process, developed by a team of researchers from the Japan Institute of Energy Innovation, employs a specialized chemical treatment that selectively extracts lithium from battery waste. According to METI officials, this method surpasses current recycling techniques, which typically recover around 50-70% of lithium. The process has been tested on used EV batteries collected from various manufacturers, with initial results confirming recovery rates of up to 90%. The technique is also designed to be environmentally friendly, utilizing fewer hazardous chemicals than existing methods.Japan’s Ministry of Economy, Trade and Industry stated that this breakthrough could significantly reduce the country’s dependence on imported lithium and support the domestic EV and battery manufacturing sectors. The new method is slated for further pilot testing before commercial deployment, which could begin within the next 12 to 18 months. Industry experts see this as a potential game-changer in how EV batteries are recycled worldwide, aligning with global efforts to create a circular economy for critical materials.
Implications for Global Battery Supply Chains
This development is significant because it offers a scalable solution to the growing challenge of recycling lithium, a key component in EV batteries. Recovering up to 90% of lithium from used batteries could drastically reduce the need for new lithium mining, which is environmentally damaging and geopolitically sensitive. For Japan, this means greater self-sufficiency in battery materials and a competitive edge in the global EV market. Internationally, if adopted widely, this method could lower costs and environmental impacts associated with lithium extraction and processing, supporting global sustainability goals.
