One such technology is energy storage based on phase change materials (PCMs), which helps address temporal, spatial, and intensity mismatches in energy supply and demand. Scholars have combined energy storage technology with floor heating technology to establish energy storage floor heating systems [ [6], [7], [8] ].
It restricts the application potential of energy storage systems due to the higher heat conductivity and density of typical PCMs and their low phase change rates. Thus, increased thermal conductivity can be achieved by adding highly conductive materials in various methods [225] .
As a well-known latent heat storage material, PCMs realize the storage and release of thermal energy during phase change process [15]. Because of their temperature within a certain range, PCMs are widely used in building energy conservation, electronic components, and lithium-ion batteries [16,17].
Phase change materials (PCMs) are commonly used for latent heat storage due to their ability to absorb thermal energy during phase change that can be extracted at a constant uniform temperature. PCMs melt at their melting point by absorbing the excess heat during charging.
