Structural elucidation of the degradation mechanism of nickel-rich layered cathodes during high-voltage cycling
Abstract:
Phase transition occurring during cycling plays a fundamentally important role in the cycling performance of nickel-rich cathodes. Here, splitting of two O3 phases, rather than the often observed O1 phases in the conventional LiCoO$_{2}$ electrode, was discovered in LiNi$_{0.85}$Co$_{0.10}$Mn$_{0.05}$O$_{2}$ at a high-voltage region (>4.6 V). Such degradation could be mitigated via Al doping.
