Abstract Scope |
Sorption-based thermal energy storage (TES) materials have the potential to improve system efficiency and reduce the mass and complexity of thermal management systems. However, they are limited by 1) slow response times, particularly time associated with the absorption recharge process and 2) insufficient energy storage densities. Here, we investigate desorption/ evaporation from an open composite TES materials system, recharged using liquid water. The recharge time is improved by an order of magnitude over traditional vapor recharge time while achieving reversible energy storage densities greater than 1 MJ/kg over >100 cycles. We introduce binder density-chemistry, hydration level, and external pressure as tunable parameters to achieve varying cooling powers. We report transient temperature rises for heat fluxes up to 4 W/cm2. This combination of extremely high energy density and high cooling power capacity hold promise for a range of thermal management applications, specifically in aerospace and automotive industries. |
