A new composite thermochemical heat storage (TcHS) material was proposed herein with good heat storage performance and desirable stability, which was prepared by using solid-state cold pressing with a zeolite molecular sieve (ZMS) and two salts (CaCl2 and MgSO4). First, the optimized mass content (C...
