Consolidating Surface Lattice via Facile Self‐Anchored Oxygen Layer Reconstruction Toward Superior Performance and High Safety Nickel‐Rich Oxide Cathodes
Beijing Institute of Technology · Chongqing University of Technology
Abstract
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 to oxygen lattice destabilization. Herein, this work reports a straightforward approach to stabilizing the surface oxygen framework by inducing surface reconstruction via swift proton exchange and heat treatment in argon atmosphere. The robust surface structure with localized disordered phase domains effectively suppresses interfacial parasitic reactions in highly delithiated cathodes and reduces detrimental phase degradation. Enabled by the strongly…
