Toray Unveils Scalable Breakthrough in Lithium Recovery Technology for High-Efficiency EV Battery Recycling
As electric-vehicle adoption expands at record speed, the demand for reliable, sustainable recycling systems has never been higher. Lithium, the backbone of modern battery manufacturing, remains one of the most valuable materials to recover. However, current recycling operations often lose large portions of this critical resource. Toray Industries has announced a major advancement that could reshape the future of battery material circularity: a scalable nanofiltration system engineered to recover more than 95% of lithium from spent lithium-ion batteries.
This next-generation solution, rooted in high-durability membrane science, marks a significant leap forward in lithium recovery technology. Toray believes the innovation will close one of the most persistent gaps in today’s recycling chain and accelerate the development of a true closed-loop lithium cycle.
A New Era for Lithium Recovery in EV Supply Chains
As decarbonisation efforts intensify globally, EV manufacturers are shifting rapidly toward large-scale production. This growth places immense pressure on mineral supply chains, especially for lithium. Compounding the challenge is the rise of nickel- and cobalt-free lithium iron phosphate (LFP) batteries, which are being deployed worldwide due to their durability and lower cost.
While LFP batteries reduce dependence on scarce metals, they dramatically increase the volume of lithium needed to support battery-grade production. Toray’s lithium recovery technology directly addresses this urgency by enabling efficient extraction not only from NMC and NCA chemistries but also from LFP batteries, which historically have been more challenging to process.
The company notes that its membrane system can simultaneously recover other valuable metals, including cobalt and nickel, strengthening the economic viability of recycling at industrial scale.
Engineering a Membrane Capable of Surviving Harsh Leachate Conditions
Toray’s research team previously deployed nanofiltration membranes for extracting lithium from natural brines and salt lakes. Moving from brines to end-of-life batteries, however, required an entirely different level of durability.
During black-mass processing—one of the key stages in battery recycling—materials are exposed to highly acidic sulfuric-acid leachate created during the heat treatment and dissolution of battery components. Traditional membranes simply cannot withstand these corrosive conditions, making selective separation nearly impossible.
Toray responded by designing a membrane with exceptional acid resistance and long-term durability. This enhanced structure allows the material to maintain high selectivity even in extreme pH environments. According to the company, the result is the world’s first nanofiltration membrane explicitly engineered to separate and reclaim lithium from sulfuric-acid leachate with both precision and stability.
This breakthrough forms the foundation of Toray’s next-generation lithium recovery technology, enabling consistent performance across diverse battery types and recycling streams.
How the New Nanofiltration Process Works
The scalable process begins by filtering leachate generated from black mass derived during heat treatment of spent lithium-ion batteries. Toray’s membrane enables selective retention and passage, separating lithium ions from the mixture with high efficiency. This helps purify the lithium stream while allowing recovery of other metals as needed.
By integrating this nanofiltration step into existing recycling setups, operators can significantly reduce material loss and improve overall process economics. Importantly, the technology is designed for mass production, meaning recyclers can adopt it without requiring major shifts in infrastructure.
Laboratory testing delivered remarkable results. Toray reports that its membrane system consistently achieved lithium recovery rates above 95%, marking a substantial performance improvement over many current recycling pathways.
This positions the innovation as a central pillar of modern lithium recovery technology, capable of boosting sustainability throughout the battery lifecycle.
Supporting the Global Push Toward Closed-Loop Lithium Systems
Accelerating recycling is essential for stabilizing lithium supply chains, reducing environmental impact, and lowering the carbon footprint of battery production. Toray’s development aligns closely with international goals for strengthening resource circularity and reducing reliance on mined materials.
Efficient recycling also supports regional independence. Countries investing heavily in EV manufacturing—including the EU, US, China, and South Korea—are prioritizing domestic supply resilience. High-performance lithium recovery technology creates a reliable pathway for turning spent batteries into new raw materials, reducing vulnerability to global supply disruptions.
The ability to recover lithium at such high rates will help manufacturers reduce cost pressures and smooth the transition toward sustainable, long-term energy storage systems. lithium recovery technology
