| Abstract Scope |
Inorganic hydrated salt-based phase change materials (PCMs) are promising for thermal energy storage due to their high latent heat and low cost. This study develops a composite PCM system using CH3COONa·3H2O and Na2SiO3·5H2O as the matrix, with SrCO3 as a nucleating agent. The effects of varying SrCO3 mass ratios on supercooling, phase transition temperature, and enthalpy were systematically investigated. Results indicate that SrCO3 significantly reduces supercooling, with an initial decline followed by an increase as SrCO3 content rises. Notably, the composite system with a CH3COONa·3H2O to Na2SiO3·5H2O mass ratio of 6:4, doped with 2 wt% SrCO3, demonstrated the optimal overall performance: a supercooling degree of 4.9 °C, a phase transition temperature of 53.1 °C, and a latent heat of 208.69 J/g. This work demonstrates a facile strategy to mitigate supercooling in hydrated salt PCMs, advancing their practical applications in energy storage. |
