Outline of Final Research Achievements

Thermo-chemical energy storage system based on gas-solid reaction is widely investigated in view of utilization of industrial waste heat. However, this energy storage system is not in practical use due to its reactivity. In this work, metal-salt/PCP (Porous Cordinatiion Polymer) composites were prepared, and reactivity of these materials were investigated.
It was shown that CaCl2/ZIF-8 composite has a good stability under cyclic reaction condition with dehydration and hydration.
