It is noteworthy that the experimental analysis of active cathode material loss generally involves the formation of rock-salt phase and isolated cathode materials induced by intergranular fracture . Since this study does not explicitly consider crack formation, only qualitative comparisons are made between predictions and experimental characterisations. Fig. shows that the total loss of active cathode material increases with higher charging rate according to experimental characterisation , which aligns with the predicted results. For example, increasing the charging rate from 0.5 C to 6 C leads to an increase in the loss of active material from 8.5% to 16% . Furthermore, experimental characterisation reveals that the capacity fading of cells using small cathode particles (average diameter of 11 µm) can be reduced from 22.1% to 16.6%, compared to those with large cathode particles (16 µm) . This capacity fading mechanism is generally attributed to the loss of Li inventory, plating of Li, and loss of active material from both electrodes.
