Enhancing the Kinetics of Li‐Rich Cathode Materials through the Pinning Effects of Gradient Surface Na⁺ Doping

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.
