Operando Strain Analysis of Electrodes Using Internal Sensors and Holistic Electrochemical-Microstructural Modeling: experimental data and DFN (PyBaMM) parameter set

Hello, you will find here the raw data and DFN parameter set for the publication "Operando Strain Analysis of Electrodes Using Internal Sensors and Holistic Electrochemical-Microstructural Modeling". The electric, FBG and temperature data for each cell (Ce1, Ce2 and Ce3) are organised as follows: The electrical cycling and FBG data for the experiments at C/3 and C/20 are included in a single data file with a shared time axis. The experimental data for 1 C cycle is distributed as per cell because channel boosting was required. For the time period between the calibrations, refer to Table 1 in the publication or use the time stamp of the time-series given in the ISO 8601 format (yyyy-mm-ddTHH:MM:SS). Each set contains time-series data for each (U, I) of the cycling unit, the Bragg wavelength of the FBG sensors (as described in the publication CeX_cen or CeX_out) and the temperatures of the type K temperature sensors on the cells (T_Ce1, T_Ce2 and T_Ce3). The ambient temperature is set to 25 °C using the Binder KB110 climate chamber for all experiments. The Doyle Fuller Newman model parameter set was used within the PyBaMM modelling framework (ver. 25.1.1) and is provided here. Efforts are being made to release it within the PyBaMM ecosystem. General hints: Sign convention for the current: positive values (I>0) corresspond to discharging the battery cell. Only raw data is provided without filtering or restriction of the data range.
