Abstract :
Lithium-ion battery performance, aging and safety response occurs in complex relations among various physics, at intricate geometries, and in varied length and time scales. Through a multi-year effort, U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has developed a multi-domain modeling approach known as the Multi-Scale Multi-Dimensional (MSMD) framework. This presentation will introduce a general multi-scale multi-physics lithium-ion battery model framework, the MSMD model framework. The MSMD model introduces multiple coupled computational domains to resolve the interplay of lithium-ion battery physics in varied length scales. Model geometry decoupling and domain separation for the physicochemical process interplay are valid where the characteristic time or length scale is segregated. Assuming statistical homogeneity for repeated architectures typical of lithium-ion battery devices is often adequate and effective for modeling submodel geometries and physics in each domain. The modularized hierarchical architecture of the model provides a flexible and expandable framework facilitating modeling of the multiphysics behavior of lithium-ion battery systems. This presentation will introduce several applications of the model that resolves electrochemical-, electrical-, and thermal-coupled physics in various lithium battery systems.
