Direct recycling, based on chemical relithiation methods, presents a promising approach to address compositional and structural defects in degraded cathodes without sacrificing the embedded energy in the materials. This method enables the production of cathodes that directly usable in the assembly of new batteries, eliminating the need to resynthesize cathodes from their precursors. Compared to pyro-and hydro-recycling routes, direct recycling offers significant advantages in terms of energy consumption, safety, cost, flexibility, and economic returns, attracting considerable attention from academia and industry.
