In addition, the influence of bending on the impedance behavior of battery cells, especially the prismatic cells, and the underlying mechanisms still need to be elucidated. In this study, we focus on the mechanical damage of prismatic cells during three-point bending and its correlation with the ISC and impedance behaviors.
Three-point bending tests were firstly conducted for different pouch battery configurations to obtain force–displacement curves. A finite element model of the pouch battery under the three-point bending was then simulated employing a homogenization technique to reduce the simulation cost and time consumption significantly.
The first set of simulations will be the three-point bending of the cell, where the tension properties play an equally important role as the compression. Then, the in-plane loading of the cell is simulated.
Three-point bending tests have not been previously performed on these cells. For the current study, longitudinal and transverse three-point bending tests were performed on the pouch cell. In the longitudinal bending setup, the long side of the cell goes under bending, while in the transverse bending the shorter side of the cell bends.
The three-point bend results in compression of the electrode layers closest to the loading nose and tension in the layers opposite the loading nose, hereafter referred to as “upward-facing” and “downward-facing,” respectively.
In this method, the inputs are the compression strength of a cell in TTD and in-plane directions as well as three-point bending load-displacement tests data and the outputs will be the tension strength of the battery cell in the in-plane directions. 3.1. Analysis of three-point bending test
