Uncovering the Critical Role of Ni on Surface Lattice Stability in Anionic Redox Active Li1.2Ni0.2Mn0.6O2

Carbon Energy
Anionic redox reaction (ARR) can provide extra capacity beyond transition metal (TM) redox in lithium‐rich TM oxide cathodes. Practical ARR application is much hindered by the structure instability, particularly at the surface.
