Abstract Facing the resource and environmental pressures brought by retiring wave of lithium‐ion batteries (LIBs), direct recycling methods are considered to be next generation's solution. However, contradiction between limited battery life demand for rapidly iterating technology forces recovery paradigm shift toward “direct upcycling.” Herein, a closed‐loop upcycling strategy that converts waste current collector debris into dopants is proposed, highly inclusive eutectic molten salt system utilized repair structural defects in degraded polycrystalline LiNi 0.83 Co 0.12 Mn 0.05 O 2 cathodes while achieving single‐crystallization transformation introducing Al/Cu dual‐doping. Upcycled materials can effectively overcome two key challenges at high voltages: strain accumulation lattice oxygen evolution. It exhibits comprehensive electrochemical performance far superior commercial 4.6 V, especially its fast charging capability 15 C, an impressive 91.1% capacity retention after 200 cycles 1.2 Ah pouch cell. Importantly, this approach demonstrates broad applicability various spent layered cathodes, particularly showcasing value mixed cathodes. This work bridges gap management material enhancement, offering sustainable path LIBs production next‐generation high‐voltage

Surface Catalytic Repair for the Efficient Regeneration of Spent Layered Oxide Cathodes

Journal of the American Chemical Society, Год журнала: 2024, Номер unknown

Опубликована: Сен. 24, 2024

Direct recycling is considered to be the next-generation technology for spent lithium-ion batteries due its potential economic benefits and environmental friendliness. For layered oxide cathode materials, an irreversible phase transition a rock-salt structure near particle surface impedes reintercalation of lithium ions, thereby hindering compensation process from fully restoring composition defects repairing failed structures. We introduced transition-metal hydroxide precursor, utilizing catalytic activity produced during annealing convert into that provides fast migration pathways ions. The material repair synthesis processes share same heating program, enabling added precursor undergo topological transformation form targeted oxide. This regenerated exhibits performance superior commercial cathodes maintains 88.4% initial capacity after 1000 cycles in 1.3 Ah pouch cell. Techno-economic analysis highlights advantages over pyrometallurgical hydrometallurgical methods, indicating practical application.
