| Abstract Scope |
Separators are critical to both the safety and performance of advanced lithium batteries. Separator design is an active area of research and considers many different structural and materials designs. In the design of separators both the materials and microstructure need to be accounted for, as they both influence the transport species, heat transfer, active sites and reactivity. In this work, we use numerical models to study the interplay of the materials and microstructure on the formation of dendrites in lithium batteries. Using numerical methods, we investigate the effects of the microstructural properties on reactive transport in the battery and the growth and morphology of dendrites. A mesoscale model of the multiphase separator is used to study how the geometry, pore size, porosity and tortuosity influence dendrite growth. Included in these studies are the effect of heterogeneous structures and the use of functional separators to improve battery performance. |
