Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
In the phase transformation of the PCM, the solid–liquid phase change of material is of interest in thermal energy storage applications due to the high energy storage density and capacity to store energy as latent heat at constant or near constant temperature.
To meet the demands of the global energy transition, photothermal phase change energy storage materials have emerged as an innovative solution. These materials, utilizing various photothermal conversion carriers, can passively store energy and respond to changes in light exposure, thereby enhancing the efficiency of energy systems.
In particular, the melting point, thermal energy storage density and thermal conductivity of the organic, inorganic and eutectic phase change materials are the major selection criteria for various thermal energy storage applications with a wider operating temperature range.
During the phase transition process, PCMs store thermal energy in the form of latent heat. This method is more efficient and steadier compared to other types of heat storage media, such as sensible heat and chemical reaction heat.
