Rechargeable batteries are vital to the energy transition, with NMC (Lithium Nickel Manganese Cobalt Oxide) cathodes remain the preferred option for capacity and fast charging. However, large-scale recycling remains economically inefficient, especially in the Asia–Pacific region, where upscaling the method of pairing recycling with raw mineral extraction has not yet succeeded. This project integrates chemistry and engineering knowledge to improve leaching and separation efficiency while reducing energy use, reagent usage, and equipment strain. By combining reaction kinetics with dynamic process parameters, the model will optimize metal recovery, shorten operation time, and lower overall energy and reagent demands.
