Graphene Aerogel Based Thermal Energy Storage Using PCM

This study presents a comprehensive review of graphene aerogel-based composites developed for thermal energy storage (TES) and insulation applications. Graphene aerogels, known for their ultra-low density, high porosity, and exceptional thermal stability, serve as a promising matrix for embedding phase change materials (PCMs) such as polyethylene glycol and inorganic salts. The integration of zeolites further enhances the composite’s performance by enabling moisture regulation and improving latent heat retention. These multifunctional composites demonstrate high thermal conductivity, excellent energy storage capacity, and structural integrity, making them suitable for aerospace, building insulation, and advanced thermal management systems. The proposed multilayer composite structure—comprising a graphene aerogel matrix, embedded PCM layer, zeolite layer, and a final insulating aerogel layer—offers a novel approach to achieving efficient, compact, and stable TES solutions.
