Syensqo and cylib have achieved a breakthrough in circular battery materials processing, successfully producing high-purity lithium hydroxide from end-of-life EV batteries.
By extracting and purifying lithium from shredded electrode “black mass” of both NMC and LFP chemistries on a single production line, this pilot‐scale process streamlines recycling, boosts versatility, and could lower capital expenditures.
Using cylib’s lithium-rich effluent and Syensqo’s proprietary CYANEX® 936P solvent co-developed with Tenova Advanced Technologies the partners demonstrated an end-to-end workflow of extraction, purification, conversion, and crystallization that yields battery-grade lithium hydroxide meeting, and in some cases exceeding, top cathode‐active‐material specifications.
This milestone also supports EU Battery Regulation (EU) 2023/1542 targets, which mandate recovery of at least 50% of lithium from battery waste by 2027 and 80% by 2031.
