New paper published in Separation and Purification Technology on the electrochemical recovery of lithium-ions from spent battery cells

New paper published in Separation and Purification Technology on “Optimized electrochemical recovery of lithium-ions from spent battery cells using carbon-coated lithium iron phosphate”. We optimized a system based on carbon-coated lithium iron phosphate electrodes. The electrodes selectively extract lithium ions from complex leaching solutions derived from real LCO (LiCoO₂) cathode materials. Over the course of […]
