Fig. 2

The predicted RUL of 25C05–25C08 testing cells a–d cycled at 25 °C (shown as green curves). The end of life (EoL) of these four testing cells is 150, 120, 30 and 38, respectively, which is defined as the cycle number when the capacity drops below its initial 80%. The testing EIS spectra are collected at the state V (15 min resting after fully charging). The shaded region indicates  ±1 standard deviation. R2 is shown on the right bottom in each panel.
