Thermal Analysis of the Gelation Process of Li-ion Battery Polymer Electrolyte by Electron Irradiation Using Multi-physics Simulation
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 significant safety risks, especially in electric vehicles. To address this, the process of gelation through cross-linking has emerged as a promising solution, effectively 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 efficient 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.
期刊介绍:
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
