The electrification revolution in the automobile industry and other sectors demands an annual production capacity of batteries on the order of 10² gigawatt-hours, posing a significant challenge for the supply of essential materials like cobalt and nickel, as well as their recycling at the end of the battery life cycle. Current methods, such as pyrometallurgical and hydrometallurgical recycling, are often hindered by complexities, high costs, and secondary pollution. This study presents a direct-recycling method using molten salts (MSDR) that is both environmentally friendly and economically viable, supported by a techno-economic analysis utilizing real-world data and price information. We demonstrate the practicality of MSDR by converting low-nickel polycrystalline LiNi0.5Mn0.3Co0.2O2 (NMC) cathode material, frequently used in early electric vehicles, into nickel-rich (Ni > 65%) single-crystal NMCs. The resultant single-crystal cathodes exhibit an increase in energy density of more than 10%, highlighting the method's potential to enhance performance while promoting sustainable recycling practices.
