Rock Salt Cathodes: Impact of Local Separation on the Structural and Electrochemical Behaviors in Li₂MoO₃LiCrO₂ Disordered Rock‐Salt Cathode Material (Adv. Energy Mater. 3/2021)

In article number 2002958 Won-Sub Yoon, and co-workers explore various structural and electrochemical phenomena associated with elemental segregations in Li1.233Mo0.467Cr0.3O2 disordered rock-salt cathode material. The impact of a unique Mo–Mo bond on the lattice stability is investigated. A separation between Mo/Li-rich and Cr/Li-poor domains is observed. Based on this, the mechanisms of the domain-dependent kinetics, asymmetric Li+ diffusion, and linked hysteresis/degradation processes are explained.
