LiNiO2 Cathodes
In article number 2211515, Weibo Hua and co‐workers depict that oxygen ions are gradually released from surface lattice of LiNiO2 (Rm) 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...
One of the major challenges facing the application of layered LiNiO2 (LNO) cathode materials is the oxygen release upon electrochemical cycling. Here it is shown that tailoring the provided lithium content during synthesis process can create a disordered layered Li1‐xNi1+xO2 phase at the primary particle surface. The disordered surface, which serves as a self‐protective layer to alleviate the oxygen...
