Lithium chloride (LiCl)-modified magnesium hydroxide (Mg(OH)2) is a material that is used for chemical heat pumps. LiCl-modified Mg(OH)2 is able to store thermal energy at around 250°C. LiCl-modified Mg(OH)2 was examined using 1, 7, and 105 runs of a cyclic dehydration and hydration operation. The sample was dehydrated at 250°C and hydrated at 110°C in this study. As a result, it was found that the hydration conversion (which corresponds to the heat output performance) decreased from 81.1% to 65.7%. There were no LiCl needle-like crystals on the sample before the cyclic operation. On the other hand, after 105 runs of the cyclic operation, the sample showed LiCl needle-like crystals. The reason for the decrease in the reactivity of the LiCl-modified Mg(OH)2 could be a change in the surface modification state.
