报告简介:

Thermal energy storage (TES) refers to a collection of technologiesthat store energy in the forms of heat, cold or their combination, whichcurrently accounts for approximately 55% of global non-pumped hydro storageinstallations. This presentation will first briefly outline the background andchallenges of thermal energy storage. Recent progress will then be summarizedin TES materials, components and devices and system integration, with a focuson materials formulation based on molecular scale modelling validated throughmeasurable macroscopic properties, and manufacture of the materials viainnovative use of conventional powder technology. TES can be sensible heat,latent heat or thermochemical based. This talk shall use the latent heatstorage materials, often called phase change materials (PCMs), as an example,particularly inorganic salts based PCMs. Two key challenges for such materialsare chemical incompatibility and low thermal conductivity. The use of compositematerials provides an avenue to meeting the challenges. Such compositematerials use a structural supporting material and a thermal conductivityenhancement material. It will show that a right combination of the salt, thestructural supporting material and the thermal conductivity enhancementmaterial could give a hierarchical structure that is able to contain the moltensalt and give a substantial enhancement in the thermal conductivity.
