Abstract
This work deals with the development of thermal energy storage (TES) materials with improved performance by direct ink writing (DIW) of highly porous (85 % total porosity) 3D coaxial ceramic supports for the encapsulation of phase change materials. These supports consist of rods with a boron nitride/vermiculite (77/23 by volume) composite core and a vermiculite shell. The approach is based on introducing a highly thermally conductive core into the filaments to improve the efficiency of the 3DTES structures, while maintaining a highly porous clay shell with a reported ability to be infiltrated by sodium nitrate and solar salt. A comparative study of the TES performance is conducted evaluating the thermal energy storage efficiency, thermal stability, energy storage density, and thermal conductivity. As demonstrated by finite element simulations, the enhanced thermal response of the coaxial 3DTES can be attributed to a multi-layered configuration of the filaments, also responsible for the increased anisotropy.
期刊介绍:
The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
