Figure 1: Gliding barriers for LiCoO₂ from a pure O3 stacking to a structure containing a O1 stacking fault for different lithium contents. The barriers have been obtained by performing solid-state nudged elastic band calculations within density function theory. The barriers and stacking fault energies are insightful to understand stacking sequence changes (i.e., phase transitions) as a function of the lithium content as well as the mechanical behaviour of the material.
