Enabling 4.6 V LiNi0.6Co0.2Mn0.2O2 cathodes with excellent structural stability: combining surface LiLaO2 self-assembly and subsurface La-pillar engineering

The solution proposed in this article is expected to provide direction for managing the internal structure and interface stability of NCM and can be extended to other cathode applications.
