Modern rechargeable batteries are complex ensembles of particles of electrochemically active material with high charge capacity utilization achieved through the development of optimized chemistries and particle architectures (see Figure on the left). The research performed by the group led by Prof. Edwin García focuses on the development of thermodynamic and kinetic theories, models, and algorithms to realize improved portable and stationary energy storage technology. In order to incorporate the effects of the mesoscale microstructure and tortuosity, a theoretical framework is being developed to establish processing-property relations that combine the constitutive properties of the individual phases into realistic microstructural designs. The developed framework is directly compared against experimental results. The goal is to develop accelerated design strategies, advanced architectures (microstructures), and processing operations for high power density applications.
