Based on the theory of crystallography, the electrostatic potential energy model of hydrotalcite-like hydrotalcite was established. The electrostatic potential energy of interlayer anions in Mg-Al hydrotalcite supramolecular system composed of 20 layers and 2107 anions per layer was theoretically calculated. The results show that the molar ratio of metal ions in the modified layer affects the charge density of the plate and the distance between the layers. The calculated electrostatic potential of the anion is consistent with its thermal stability. The charge and size of the intercalated anion directly affect the potential energy of the anion size.
