Non-equilibrium thermodynamics in porous media : battery degradation, and sorption and transport in porous materials
Porous media offer many interesting problems in physics and engineering due to the interaction of phase transitions, surface effects and transport. In this thesis I examine two such problems: the degradation of lithium-ion batteries, and sorption and transport of fluids in porous materials. The …

A combined modeling and experimental study assessing the impact of fluid pulsation and operating schemes on charge and energy efficiency in capacitive deionization
… CDI, we show that salt residue within electrodes introduces a temporal lag between charge and desalination stages of a CDI cycle. Without accounting for this effect in the collection of effluent, significant performance degradation occurs as current density increases. To overcome this …

Learning the Electrochemistry of Degradation and Safety in Graphite Porous Electrodes for Lithium-ion Batteries
… costly experimentation or computationally heavy modeling. Specifically for designing batteries with better lifetime and long-term capacity retention, relying on just experiments can take between weeks to months and thousands of cells to get any robust insights for process improvement. Data-driven …

Numerical investigation of ion transport mechanisms in electrochemical energy storage devices: Similarity correlation and exergy destruction analysis
… the ion transport mechanisms are studied by modeling redox flow batteries (RFBs) and intercalation-based Li-ion batteries. Redox flow batteries are an emerging technology which allows independent scaling of energy and power density making them suitable candidates for grid-scale energy …
