LiNiO2 Cathodes(#br)In article number 2211515, Weibo Hua and co‐workers depict that oxygen ions are gradually released from surface lattice of LiNiO2 (R3ˉ$\bar{3}$m) cathode material upon electrochemical cycling, resulting in the formation of a macroporous architecture and the reduction of nickel ions. Such chemomechanical degradation can be effectively mitigated through introducing a thin lattice‐coherent disordered Li1‐xNi1+xO2 phase in the primary particle surface.
