Nickel-rich layered cathode materials deliver high energy density but suffer from rapid capacity fading owing to various side reactions at the cathode–electrolyte interface. A proposed near-surface modification of nickel-rich cathode materials increases their cycling stability, enabling the realization of high-energy-density and durability requirements for practical application.
