Towards High Energy Density, High Conductivity Thermal Energy Storage Composites
ASME 2012 Third International Conference on Micro/Nanoscale Heat and Mass Transfer, 2012Thermal energy storage (TES) materials absorb transient pulses of heat, allowing for rapid storage of low-quality thermal energy for later use, and effective temperature regulation as part of a thermal management system. This paper describes recent development of salt hydrate-based TES composites at the Air Force Research Laboratory.

Polymer-Based Dielectrics with High Energy Storage Density
Annual Review of Materials Research, 2015Polymer film capacitors are critical components in many high-power electrical systems. Because of the low energy density of conventional polymer dielectrics, these capacitors currently occupy significant volume in the entire electrical system. This article reviews recent progress made in the development of polymer dielectrics with high energy storage ...

High Density Thermal Energy Storage With Supercritical Fluids
ASME 2012 6th International Conference on Energy Sustainability, Parts A and B, 2012A novel approach to storing thermal energy with supercritical fluids is being investigated, which if successful, promises to transform the way thermal energy is captured and utilized. The use of supercritical fluids allows cost-affordable high-density storage with a combination of latent heat and sensible heat in the two-phase as well as the ...
