Innovative Battery Recycling Methods

An everyday kitchen cupboard essential has just been used by UK academics to simplify and decarbonise the recycling of batteries from electric vehicles, energy storage systems and consumer electronics. How many leading research breakthroughs list a key component as humble as "vegetable oil (Rapeseed Oil (100%), Morrisons, UK)"? The University of Leicester's team from the world-leading ReLiB Project used ultrasound to mix water and vegetable oil, resulting in stable nano-droplets of oil in the water, and then added "black mass" from End of Life lithium-ion cells, which is a shredded mixture of all of the materials from the cell. The anode material (-ve electrode), graphite, is hydrophobic like the vegetable oil, so is attracted to it and forms clusters with the oil nano-droplets, which float to the top of the mixture and can be easily skimmed off. The cathode material (+ve electrode), lithium metal oxides such as NMC, is hydrophilic, so sinks to the bottom of the mixture. This could reduce reliance on the high temperature furnaces or strong acids used in older recycling techniques, while keeping the battery-grade structure of the materials that are recovered from the black mass, so they require less processing before being used in new cells. Overall, this breakthrough could make battery recycling less energy-intensive, lower-carbon and more eco-friendly. https://lnkd.in/ee4nin4s

Commercially viable lithium extraction from spent batteries. (Illinois.edu) "A new study shows that lithium can be recovered from battery waste using an electrochemically driven recovery process. The method has been tested on commonly used types of lithium-containing batteries. "The study, led by University of Illinois Urbana-Champaign chemical and biomolecular engineering professor Xiao Su, describes a process that leaches metals from batteries into an organic solvent, then uses an electrochemical cell in which a polymer-coated electrode is used to capture lithium." “The main challenge is the presence of other metals in lithium recovery streams, particularly in organic leachates, which is a common way to dissolve spent batteries for recycling,” Su said. “To overcome these challenges, we’ve introduced a copolymer that captures lithium selectively directly from organic solvents and that can be electrochemically regenerated.” "In the lab, Su’s research team dismantles batteries and leaches out metals into an organic solvent, creating a mixture containing lithium and other metals. They then moved the solvent into an electrochemical cell with an electrode coated with a specially designed copolymer that specifically captures lithium ions from the mixture, much like a sponge." “The lithium-filled electrode is then put into a new solution, and a voltage is applied,” Su said. “That triggers the polymer to release the captured lithium ions, which are collected, while leaving other metals behind in the original leachate. This electrochemical regeneration allows for repeated cycles of selective, efficient lithium recovery from waste batteries.” "Techno-economic analysis highlights high energy efficiency and competitive lithium pricing to the market value (∼$12.7 per kgLi)." https://lnkd.in/gyyW4N4B

Ultra-Green solvent battery recycling is quietly becoming a first-order materials breakthrough. For years, battery recycling meant one of two bad options: high-temperature smelting or aggressive acids. Both recover metals... neither scales cleanly. What changed in early 2026 is subtle but important. Researchers demonstrated a mild deep-eutectic solvent system, combined with integrated chemical + electrochemical leaching, that recovers >95% of Ni, Co, Mn, and Li — even from messy, mixed black mass. This isn’t incremental. It proves something uncomfortable: recycling efficiency is now a solvent-engineering problem, not a brute-force process problem. The materials science beneath the headline is the real shift: → selective solvation of transition metals from heterogeneous feedstock → controlled complexation that suppresses cross-contamination → electrochemical steps that tune redox states without thermal abuse Recycling just crossed a line. It’s no longer a dirty back-end operation. It’s becoming a front-end materials design discipline, where solvent chemistry dictates resource security. The next generation of battery materials won’t just be mined or synthesized. They’ll be designed to be recovered... cleanly, selectively, and at scale. This is where sustainability stops being a slogan and becomes a material advantage. #MaterialScience #Innovations #Batteries

💧 𝐇𝐲𝐝𝐫𝐨𝐦𝐞𝐭𝐚𝐥𝐥𝐮𝐫𝐠𝐲: 𝐄𝐱𝐭𝐫𝐚𝐜𝐭𝐢𝐧𝐠 𝐭𝐡𝐞 𝐅𝐮𝐭𝐮𝐫𝐞 𝐨𝐟 𝐁𝐚𝐭𝐭𝐞𝐫𝐲-𝐆𝐫𝐚𝐝𝐞 𝐌𝐞𝐭𝐚𝐥𝐬 ⚡ As the world accelerates toward electric mobility and renewable energy, the demand for lithium, nickel, cobalt, and manganese is skyrocketing. But with it comes a crucial question… how do we extract these metals sustainably and efficiently? Enter Hydrometallurgy… a powerful, solution-based approach using aqueous chemistry to recover and refine critical metals from ores and spent batteries. 🔬 Why Hydrometallurgy Matters: 1. ♻️ Enables metal recovery from battery waste, closing the loop toward a circular economy. 2. 💧 Offers selectivity and purity control, producing battery-grade precursors with minimal impurities. 3. 🌱 Operates at lower temperatures compared to pyrometallurgy, cutting energy use and emissions. 🚧 But challenges remain: • Handling complex leach solutions and impurities is still chemistry-intensive. • High reagent consumption and wastewater management need green innovation. • Scaling lab processes to industrial levels demands cost-efficient process integration. ⚙️ The road ahead: Hydrometallurgy will evolve beyond metal recovery, it will be central to urban mining, battery recycling, and sustainable resource management. With greener lixiviants, selective solvent extraction, and integrated recycling lines, the goal is clear: turn waste into wealth without harming the planet. 🌍 The next battery revolution won’t just happen in gigafactories… it will happen in the chemistry of recovery tanks. #Hydrometallurgy #BatteryRecycling #CircularEconomy #SustainableEnergy #EnergyMaterials #BatteryMetals #CleanTech

Boston College researchers discovered ‘Acidithiobacillus ferrooxidans’ bacteria that feed on spent battery materials, offering sustainable recycling solutions. The bacterium thrives in acidic environments, consuming iron and stainless steel from old batteries while extracting cathode materials effectively. Surprisingly, stainless steel worked better than pure iron as a food source. The bacteria doesn’t require sulfate, eliminating the need to transport toxic chemicals. Led by Chemistry Professor Dunwei Wang and Biology Associate Professor Babak Momeni, the team is now evolving bacterial strains for improved efficiency and building prototype batteries from recovered materials to test performance against traditional ones, published in ACS Sustainable Resource Management. #fblifestyle

⛏️ Every kWh of waste today is a mine for tomorrow if we treat it right. When people think about “battery waste,” they imagine a problem. But in reality, every kWh of production scrap is a future mine with a perfectly known geology. Think about it: 🔹 Electrode scrap Pure anode. Pure cathode. Zero unknowns. This is the cleanest feedstock any recycler will ever see. 🔹 Formation rejects Cells that failed testing but with full traceability of chemistry and batch. 🔹 Dry cells & modules High-purity, uniform materials straight from production lines. While Europe is busy worrying about critical raw material shortages… …gigafactories are generating thousands of tonnes of high-value materials every year: ✅ lithium ✅ graphite ✅ nickel ✅ manganese ✅ cobalt ✅ aluminum ✅ copper And most of it is still treated as “waste.” Here’s the truth: 💡 Waste is only waste if you mismanage it. Handled correctly, it is a strategic resource But unlocking this value requires one thing: 👉 Designing recycling and production to work together not in two separate realities. This means: ✔️ modular, chemistry-dedicated mechanical lines ✔️ clean fractions ✔️ graphite purification ✔️ LFP and NMC handled separately ✔️ stable feedstock contracts between factories & recyclers ✔️ culture change: scrap = raw material, not a problem If Europe wants a circular battery ecosystem, this is where it starts. Not in 2035. Not when EVs hit end-of-life. But today inside gigafactories. Because every kWh of waste we ignore now… is a mine we lose tomorrow. 💬 Your turn: Do you see production scrap as Europe’s most underrated source of critical raw materials? ♻️ 🔋 🐝 #CircularEconomy #BatteryRecycling #MaciejMikulicz #CEforIndustry #EPR #CSRD #CircularThinking #Resilience #TechForGood #ESG #Sustainability #IndustrialStrategy #Materialrecovery #RecyclingMarket #Closedloop #LithiumIon #EUChemistry #NMC #LFP #BlackMass
