In this work, three ionic liquids with a 1-hexadecyl-3-methylimidazolium cation were synthesized with different anions; chloride, saccharinate, and nickel tetrachloride. All the studied ILs show melting points above room temperature, ranging between 45 and 65°C and melting enthalpies close to 100 J/g, making them potentially suitable phase-change materials (PCMs) for latent heat storage. This can actually be enhanced by a suitably large heat capacity and thermal conductivity of the material both in the liquid and solid phase.
