Representation of degradation characteristics of ageing cells in the power-energy-capacity space. (a) The normalized power as a function of the normalized time for systems with different degradation mechanisms. (b) The normalized power as a function of the normalized energy for systems with different degradation mechanisms. Plot showing the normalized power as a function of the normalized time for different degraded states at different C-rates for different combinations of degradation mechanisms (c) LMO dissolution only and (d) Anode SEI only (with different resistance values). Normalization is with respect to the corresponding value at 1C of the fresh cell.
