Energy storage technologies and devices play a crucial role in improving energy efficiency. This study investigated five combinations of metallic phase change materials, namely Al-C, AlSi12-Al2O3, AlSi12-C, Sn-Al and Zn-C synthesized through a hybrid sintering method by combining a metal as the main phase change material with a skeleton material. Thorough investigations were conducted on various aspects, including thermophysical properties, strength, cycle performance, material structure, and composition. From the perspective of raw material prices, an economic analysis was conducted on the material system. The AlSi12-Al2O3 combination exhibited promising performance, demonstrating high latent heat value, compatibility, strength, energy density, specific heat capacity, thermal cycling stability, and economic effectiveness.

摘要

Energy storage technologies and devices play a crucial role in improving energy efficiency. This study investigated five combinations of metallic phase change materials, namely Al-C, AlSi12-Al2O3, AlSi12-C, Sn-Al and Zn-C synthesized through a hybrid sintering method by combining a metal as the main phase change material with a skeleton material. Thorough investigations were conducted on various aspects, including thermophysical properties, strength, cycle performance, material structure, and composition. From the perspective of raw material prices, an economic analysis was conducted on the material system. The AlSi12-Al2O3 combination exhibited promising performance, demonstrating high latent heat value, compatibility, strength, energy density, specific heat capacity, thermal cycling stability, and economic effectiveness.
