Thermal Analysis of the Gelation Process of Li-ion Battery Polymer Electrolyte by Electron Irradiation Using Multi-physics Simulation
https://doi.org/10.1007/s11814-024-00271-6
Abstract
Rechargeable lithium-based batteries play a crucial role in the shift towards renewable energy, providing eco-friendly alternatives
to fossil fuels and improving sustainability. However, their liquid electrolytes present signifi cant safety risks, especially
in electric vehicles. To address this, the process of gelation through cross-linking has emerged as a promising solution, eff ectively
reducing the risk of combustion. Traditional gelation methods are time-consuming and costly, often taking up to an
hour. In contrast, electron beam irradiation provides a highly effi cient alternative, reducing the process to just seconds. This
lowers production costs and meets the demands of high-volume manufacturing. In this study, the multiphysical phenomena
in the coin cell were simulated using, which combines radiation transport modeling, phase change simulation of the gelation
process, and thermal analysis. Through this, the peak temperature of the electrolyte in the coin cell was predicted and the
time required for the temperature of the electrolyte to return to the ambient temperature was predicted.
