Abstract: Lithium nitrate trihydrate (LiNO3·3H2O) has many traits that are desirable for thermal energy storage (TES) materials. This study tests the thermophysical properties of LiNO3·3H2O between 253-353 K in comparison to effective TES materials: water and paraffin. A Hot Disk TPS 2500S measured the thermal conductivity of the solid LiNO3·3H2O samples using the transient plane source (TPS) method. Results showed that LiNO3·3H2O had a higher thermal conductivity than paraffin, giving it the potential to be a competitive TES material in the future.
