Abstract: This paper reviews the recent developments metal-phase change material composites with a focus on thermal conductivity. There have been numerous studies in the literature using theoretical, numerical simulation and experimental methods. Metals in the composite occur mainly in three forms, porous foams metals, dispersed metallic particles, and metallic matrices. Most phase change (PCMs) have a low thermal conductivity. Addition of metallic components increases the thermal conductivity but suppresses the effects of natural convection and the heat storage capacity of heat storage apparatus when PCMs are at the liquid state. As a result, there is an urgent need for both basic and applied research on the area.

Key words: phase change materials, heat storage, thermal conductivity, metal
