COMSOL Multiphysics在锂离子电池中的应用
Application of COMSOL multiphysics in lithium-ion batteries
摘要
Abstract
As a promising energy storage system,Li-ion batteries require continuous improvements in terms of energy density,power density,reliability,and cyclic stability to meet the growing demands of large-scale energy storage,electric vehicles,and portable electronic equipment.Despite the abundance of frontier issues related to multiphysics investigations,experimental work is still challenging.However,the synergistic improvement in the conductivity and safety of electrolytes,optimization of deposition-stripping mechanisms of high-energy anodes,maintenance of cyclic voltage and capacity of high-energy cathodes,interface polarization,and capacity release under high current,and management of thermal runaway under extreme current-temperature-acupuncture conditions exist through the multifield coupling of electrical-chemical-mechanical-thermal effects.COMSOL multiphysics provides a feasible tool for solving the continuity equation coupled with multiple physical fields,considering comprehensive information such as carrier concentration,current density,electrical-chemical potential,temperature,stress/strain,and morphology evolution.This study reviews the application of tools in the electrolytes,anodes,and cathodes of lithium-ion batteries,focusing on the comprehensive influences of multifield coupling on battery performance,the multifield coupling simulation method,and the combination of theoretical,simulation,and experimental characterization.Finally,the multifield and multiscaled issues in theoretical-experimental joint research are prospected.关键词
