Thermal energy storage (TES) materials rapidly absorb and release heat to improve efficiency and to prevent devices or components from overheating and failing. Key challenges are demonstrating high energy storage density and high cooling power densities in stable, reversible systems. We have demonstrated:
- Strategies and tools for optimal design of high cooling-power thermal composites.
- Material-specific nucleation catalysts, resulting in significant decrease in subcooling in multiple classes of PCMs.
- Thermophysical properties of advanced phase change materials and composites.
- Figure of merit based approaches to directly compare the performance of different materials and optimized composites.
