In article number 1902698, Chong S. Yoon, Yang‐Kook Sun and co‐workers develop a new type of Ni‐rich layered cathode, Li[Ni 0.9 Co 0.09 W 0.01 ]O 2 for next‐generation electric vehicles. Substituting W for Al in the NCA cathode reduces primary particle size. The particle size refinement improves the cycling stability of the cathode by suppressing microcrack propagation and preventing particle fractures. Thus, the cathode delivers a high energy density with a long battery life.
