During battery operation, lithium ions follow a tortuous path around a densely packed distribution of particles. The morphology, size, and spatial arrangement of these particles directly influences the performance of a lithium ion battery in terms of the delivered power and energy density. As energy demands continue to grow and evolve,
microstructural optimization is becoming increasingly important for unlocking the full potential of lithium ion batteries. Existing microstructural optimization strategies are based on trial and error during electrode fabrication. As a part of this work, we are developing a generalized theoretical framework to evaluate the microstructural performance of different lithium-ion battery architectures, and the processing techniques used to make them.

Currently existing theories and models to describe rechargeable lithium-ion batteries are based on the well-established porous electrode theory, which assumes a uniform mixture of reactive solid particles and ignores the geometrical details of the pores, particle segregation, and clustering, particle roughness, and crystallographic or microstructural anisotropy. Such descriptions are currently…

The effects of connected porosity and graded Lanthanum Strontium Manganate (LSM) particle-based electrodes are analyzed for an electrolyte-supported, Yttria Stabilized Zirconia (YSZ), SOFC half-cell. Optimal microstructure electrodes are proposed by identifying mechanisms that control the transport of oxygen in the porous cathode electrode: 1) transport of oxygen to the cathode-electrolyte interface…

The performance of emerging chemistries for LIBs in electric and hybrid vehicle applications is greatly limited by failure during long term battery cycling. As a part of this project, we are developing theoretical and numerical methodologies to understand the underlying chemomechanical mechanisms that control lithium intercalation and degradation. Of great interest is to develop strategies to prevent/minimize…
