Many cathode degradation mechanisms are intensified in LMBs operated under high cut-off voltages, including cathode–electrolyte side reactions, bulk and surface phase transformation, cracking of the NMC secondary particles, over-growth of cathode–electrolyte interphases (CEIs), gas evolution and transition metal (TM) dissolution.
