Abstract:
The development of aqueous electrolytes exhibiting high ionic conductivities through solvent-free methods is of great significance for the progress of aqueous battery technology. This study presents a high-performance ionic conductor engineered through a synergistic chaotropic effect and defective structure using a solvent-free approach. The combination of localized acidification at vacancy sites and doping chaotropic LiI enhances ionic diffusion in D-UiO-66-LiI. The generated cationic substructure promotes ion confinement effects within the D-UiO-66-LiI pores, establishing efficient conduction pathways. Furthermore, temperature-dependent analysis reveals that thermal energy increases ion movement and weakens the hydration of Li+ ions, not only increasing ion mobility but also maintaining the water networks through dynamic hydrogen bonding reconstruction. These coordinated effects enable D-UiO-66-LiI to achieve ultrahigh ionic conductivities across wide temperature and humidity ranges.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
