Chemomechanically Stable Small Single‐crystal Mo‐doped LiNi0.6Co0.2Mn0.2O2 Cathodes for Practical 4.5 V‐class Pouch‐type Li‐ion Batteries

doping absorbs accumulated localized stress to eradicate cracks formation, subdues the surface side reactions and lattice oxygen missing meanwhile, and improves thermal tolerance at highly delithiated state. Consequently, the SS-MN6 based pouch cells are endowed with striking deep cycling stability and wide-temperature-tolerance capability. The contribution here provides a promising way to construct advanced cathodes with superb chemomechanical stability for next-generation LIBs.
