Multi-scale hybrid composites of erythritol/diatomite/GNP for enhanced thermal energy storage: experimental and machine learning optimization (opens in new tab)

Thermal energy storage (TES) using phase change materials (PCMs) is a critical technology for balancing energy supply and demand. Among sugar alcohols, erythritol stands out due to its high latent heat; however, its practical application is hindered by its low thermal conductivity and leakage during phase transition. In this study, a multi-scale hybrid approach is developed to overcome these limitations by integrating erythritol with a micro-porous diatomite framework and graphene nanoplatele...
