Role of Ordered Ni Atoms in Li Layers for Li‐Rich Layered Cathode Materials

Li‐rich layered oxide materials are promising candidates for high‐energy Li‐ion batteries. They show high capacities of over 200 mAh g−1 with the additional occupation of Li in their transition metal layers; however, the poor cycle performance induced by an irreversible phase transition limits their...
