A consistent set of parameters is essential for evaluating battery performance through electrochemical modeling. This study provides a complete physico-chemical methodology to measure all necessary parameters and evaluates battery responses against experimental curves for correlation.
To effectively evaluate battery performance by means of electrochemical modelling, a consistent set of parameters is essential. The aim of this work is to provide a complete physico-chemical methodology to measure all the necessary parameters for a pseudo-two-dimensional (P2D) electrochemical model. Com-ponent composition, thermodynamic, kinetic and transport properties, parameters related to the porous structures, internal battery configuration and full-cell electrode balancing are presented for a commer-cial lithium-ion battery. Then, the measured parameters are entered into the P2D model, and battery responses are evaluated against full-cell experimental curves (galvanostatic charge-discharge at different current rates, EIS responses and pulses) to correlate numerical-experimental results. ? 2021 Elsevier Ltd.
