In summary, at the material level, Ji et al. applied the instant Joule heating technique to upcycle S-LMO, significantly improving the electrochemical performance of the repaired materials by introducing structural defects. Building on this foundation, they provided a comprehensive blueprint for the entire solid-phase recycling process, thereby establishing a foundational paradigm for future battery recycling. At the application level, the integration of advanced technology in this work has substantially minimized resource waste, shortened repair time, and enhanced overall efficiency. With further refinement, this recycling paradigm is expected to offer considerable benefits for future industrial-scale implementation.
