Multi-dimensional modeling of thermal batteries using the Stefan-Maxwell formulation and the finite-element method

摘要

A general multi-dimensional framework for modeling thermal batteries is presented. The new framework employs the Stefan-Maxwell flux formulation for the diffusion of an arbitrary number of species in electrolytic systems, the finite-elementnumerical method, and a fully coupled implicit solution scheme via Newton's method. Preliminary results utilizing a two-dimensional LiAl/LiCl-KCl/FeS cell are presented to illustrate the utility of the framework.
