N-eicosane/expanded graphite as composite phase change materials for electro-driven thermal energy storage

Latent heat storage (LHS) is considered to be a promising technique for thermal energy storage, due to its high energy storage density and nearly constant working temperature. However, the phase change materials (PCMs) used in LHS usually suffer from low thermal conductivity. In this work, the expanded graphite (EG) was applied to support n-eicosane (C20) via vacuum impregnation to prepare C20/EG composite PCMs. The DSC analysis indicated that...
