Charge-discharge curves
Webcharge–discharge curves were recorded using a Solartron 1287 potentiostat. For cell internal resistance measurements, AC impedance spectra at a frequency range of 0.1Hz–10kHz were collected using a Solartron FRA analyzer. For a more detailed description about the measurement and calculation procedures, please see our previous … WebRUL is the number of remaining charge/discharge cycles before the battery reaches the failure threshold under certain charge/discharge conditions [].Usually, the battery reaches the end of life (EOL) when the capacity degrades to 70% or 80% of the rated capacity, and the RUL can obtain the remaining number of cycles to reach the EOL of the lithium–ion …
