Thermal and phase transition behaviors of ICM-Br, -BF4, and -TFSI exhibit significant variation based on the anion type. These differences are further reflected in the self-assembled nanostructures of the ICMs, which are characterized through X-ray and electron diffraction experiments. Ionic conductivity measured by electrochemical impedance spectroscopy and activation energy calculated by Arrhenius equation allow us to build the relationship between self-assembled nanostructures of ICMs and their activation energy. The constructed relationship between self-assembled nanostructures and activation energy can provide valuable insights for the development of novel ion-conductive materials.
