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 LiCoO₂electrode, was discovered in LiNi_0.85Co_0.10Mn_0.05O₂at a high-voltage region (>4.6 V). Such degradation could be mitigatedviaAl doping.
