As electric vehicles (EVs) and portable electronics become more common, growing volumes of end-of-life lithium-ion batteries are creating both a challenge and an opportunity. These batteries contain critical materials such as lithium, nickel and cobalt, which are essential inputs for next-generation mobility, clean energy and electronic applications. However, when not properly managed, spent batteries can contribute to environmental and safety risks, while valuable resources are lost.
Syensqo’s CYANEX® 936P is a proprietary reagent used by battery recycling companies in solvent extraction processes to recover lithium from end-of-life battery materials. CYANEX® 936P enables selective recovery and purification of battery-grade lithium hydroxide from spent lithium-ion batteries. By enabling efficient lithium recovery and reuse, CYANEX® 936P supports a more circular battery value chain and helps reduce reliance on newly mined raw materials.
Designed to work with multiple battery types on a single processing line, CYANEX® 936P improves recycling efficiency and operational flexibility. The reagent supports processing of both nickel-manganese-cobalt (NMC) and lithium-iron-phosphate (LFP) batteries, the most common EV chemistries. It can also help recyclers simplify operations by supporting recovery of metals from a range of spent battery feedstocks.
Pilot phase results have demonstrated strong performance across key sustainability and operational indicators, including:
- Over 90% recovery of critical metals from spent batteries.
- An estimated 80% lower emissions footprint compared to traditional mining operations.
- Consistent production of high-quality, battery-grade lithium hydroxide.
- Lower costs, with approximately30% lower capital expenditure and around 10% lower operating costs for lithium recovery units, enhancing scalability.
Additional benefits include reducing hazardous battery waste destined for landfill and supporting compliance with evolving battery circularity requirements.
Syensqo’s CYANEX® 936P reagent demonstrates how advanced chemistry can unlock circular value from complex waste streams. By helping turn end-of-life batteries into a reliable source of critical materials, CYANEX® 936P reduces environmental impact, strengthens supply resilience and supports the transition to a low-carbon energy future.
