Cathode

2. Cathode: Discovering new degradation mechanisms Ni-rich layered cathodes degrade due to structure driven fatigue.

Fatigued phase limits the accessible state of charge Authors propose that the fatigued phase is caused by high lattice mismatch between the cathode bulk layered structure and the rock-salt surface reconstruction layer above 75% SOC This understanding serves as a stepping stone for future Ni-rich cathode research, and may inspire the development of additives, doping agents, and coating methods.
