Progress in Simulating The Effect of Stress on The Performance of Lithium/Sodium‐Based Batteries

Abstract

AbstractLithium/sodium‐based batteries have attracted widespread attention because of their high specific capacity and excellent energy density, and have become one of the hottest research directions in energy storage devices. However, the stress accumulated during the continuous electrochemical cycle will cause the inevitable electrode failure, which inhibits the further improvement of battery performance. In order to eliminate/relieve the internal stress problem, a variety of battery material structures have been designed. In the design of battery material structure, the simulation technology is used to conduct battery modeling to predict the experimental results, which effectively reduces the range of parameters. For this reason, this paper first introduces the parameters that need to be considered by establishing stress model. Then, the utilization of simulation technology in the structural design of diverse battery materials is examined in this study. Finally, the future application of simulation technology in the field of energy storage is prospected. This is aimed to encourage the widespread utilization of simulation technology in the energy storage battery industry, with the goal of reducing design‐related energy consumption, enhancing experimental design feasibility, and minimizing experimentation costs.
