Title: Al-based metallic macrocapsule for high temperature phase change thermal storage

Abstract: Metallic phase change materials (PCMs) has advantages of high heat storage density, high thermal conductivity. This study reports a novel encapsulation method to achieve Al-based macrocapsules with good leakage prevention and high cyclability up to 500 cycles even under air atmosphere. Voids are artfully introduced inside the macrocapsules, which can accommodate large volume expansion of Al PCM during melting. For the Al@Al2O3 macrocapsules, the latent heat of Al core reaches 357.4 J/g.
