pouch-cell-thermal

Accurate thermal modelling during fast charging in large-format Li-ion pouch cells. See our paper "Electrochemical–thermal modelling of high power Li-ion pouch cells" (Journal of Power Sources, 2026).

Data:

  • Expivium.mat: Basic measurements, N x 4 matrix with columns: Sample, voltage (V), current (A), mean temperature (degC).

  • ExpIR.mat: Surface temperature (degC), Ny x Nz x N tensor where Ny and Nz are spatial dimensions (single precision).

  • 1C CC data is omitted due to bad camera calibration.
