The electrification revolution in automobile industry and others demandsannual production capacity of batteries at least on the order of 102 gigawattshours, which presents a twofold challenge to supply of key materials such ascobalt and nickel and to recycling when the batteries retire. Pyrometallurgicaland hydrometallurgical recycling are currently used in industry but suffer fromcomplexity, high costs, and secondary pollution. Here we report adirect-recycling method in molten salts (MSDR) that is environmentally benignand value-creating based on a techno-economic analysis using real-world dataand price information. We also experimentally demonstrate the feasibility ofMSDR by upcycling a low-nickel polycrystalline LiNi0.5Mn0.3Co0.2O2 (NMC)cathode material that is widely used in early-year electric vehicles intoNi-rich (Ni > 65%) single-crystal NMCs with increased energy-density (>10%increase) and outstanding electrochemical performance (>94% capacity retentionafter 500 cycles in pouch-type full cells). This work opens up newopportunities for closed-loop recycling of electric vehicle batteries andmanufacturing of next-generation NMC cathode materials.
