Peak-tracking method to quantify degradation modes in lithium-ion batteries via differential voltage and incremental capacity

•The peak-tracking incremental capacity and differential voltage model quantifies LLI and LAM;•The parameterisation process is simplified, with the versatility to use half-cell data with similar chemistries;•The accuracy of the diagnosis is minimally affected by heterogeneity during degradation;•The model is applied to 0.3 C diagnosis scan in cycling-aged cells and validated.
