Abstract

We developed a unique sequential approach for coupled mechanical-electrochemical-thermal simulation of lithium-ion batteries We conducted a series of tests to characterize the mechanical properties of each component (current collector, active materials and separator), and investigate mechanical failure behavior of a battery cell under external crush A single representative sandwich (RS) model was developed, which correlated with experimental results and predicted structural fracture Sequential mechanical-electrochemical-thermal coupled simulation was conducted using the single RS model; it predicts initiation of short circuit and consequential voltage evolution and thermal history Preliminary results were obtained by linking mechanically-deformed geometry with commercialized ECT model (CAEBAT-1 Achievement).
