Cation migration activation energies for KCHA (0.66 ± 0.10) eV, CsCHA (0.88 ± 0.01) eV and ZnCHA (0.90 ± 0.01) eV were determined (activation energy data). Good thermal stability of the materials was observed up to 710 °C (TGA data) and below 200 °C the electrical properties were strongly influenced by hydration level (conductivity, permittivity and phase angle data). Overall, it was determined that when either hydrated or dehydrated, KCHA had the highest conductivity and lowest cation migration activation energy of the three studied chabazites (activation energy data). 2017 University of Bath public RightsHolder University of Bath Seventh Framework Programme https://doi.org/10.13039/501100004963 320963 NEMESIS - Novel Energy Materials: Engineering Science and Integrated Systems European Regional Development Fund https://doi.org/10.13039/501100008530 EP/K503575/1/UNIQUIP Materials for Energy Efficient Transport (MEET) Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/E040071/1 United Kingdom Sustainable Hydrogen Energy Consortium (UK-SHEC) CORE Programme 2017 en 1 10.15125/BATH-00402 https://doi.org/10.1016/j.micromeso.2017.10.032 pub open
