Abstract Nickel‐rich oxide materials have been recognized as promising cathodes for state‐of‐art high energy lithium‐ion batteries; however, challenges remain in their commercialization due to chemical and structural degradation, poor thermal stability related oxygen lattice destabilization. Herein, this work reports a straightforward approach stabilizing the surface framework by inducing reconstruction via swift proton exchange heat treatment argon atmosphere. The robust structure with localized disordered phase domains effectively suppresses interfacial parasitic reactions highly delithiated reduces detrimental degradation. Enabled strongly anchored framework, consolidated also reinforces cathode featured higher decomposition temperature reduced release under stress. In comparison unmodified counterpart, reconstructed nickel‐rich demonstrates improved cycling rate capability. This reveals critical role of regulating on electrochemical performance behaviors, explores potential feasible modification advanced batteries.

Based on its high economic/sustainability value, the upcycling of spent cathodes into anodes has been deemed to be an alternative strategy traditional chemical synthesis. Supported by effective acid leaching and coordination-trapping self-assembly reaction, a nano-scale CoS@NSC anode was successfully prepared from LiCoO2 used as promising for lithium ion batteries.
