Abstract

Abstract : Gradient surface Na‐ion doping is realized and demonstrated as an effective strategy to enhance the kinetics of Li‐rich cathode materials. Owing to the pinning effect of Na‐doping in the Li layer, the resultant Li‐rich particles exhibit superior electrochemical performances in terms of specific capacity, Coulombic efficiency, and cycling stability.
