摘要

For large format Li-Ion cells to meet future goals of 15 year life and cost < $300/kWh, it becomes important to optimize their designs to maximize material usage and minimize thermal and electrical potential imbalances that lead to non-uniform degradation and accelerated performance loss. The typical approach of "make and break" design iterations is both expensive and time consuming. Alternately, multi-physics numerical models provide a valuable engineering platform for design trade studies by capturing the relevant electrical-thermal-electrochemical interactions occurring within realistic cell geometries.
