Ionogels have established themselves as an intriguing type of composites, owing to their distinctive properties, including superior thermal stability, non‐flammability, tunable electrochemical stability window, and high ionic conductivity. Hybrid materials based on ionic liquids (ionogels) are held together by interfaces arising out of intermolecular interactions, including electrostatic, van der Waals, solvophobic, steric, and hydrogen bonding. The interfaces within the ionic liquid (ILs) and its multifaceted interplay with the encapsulating matrix greatly influence the physicochemical and electronic/ionic interactions within the composite resulting in exceptional characteristics, allowing for the design of ionogels for targeted applications. Though ionogels have shown superior properties comparable to neat ILs, they still exhibit relatively low mechanical strength, limiting their application in several practical technologies. Simultaneous enhancement of mechanical durability while retaining high ionic conductivity is indispensable, which requires understanding interfaces and related influencing parameters. This review provides a synergetic comprehension, focusing on the interactive forces and factors affecting the conductivity, stability, and robustness of ionogels. Correlating with interfaces, several strategies, including the implications of nanofiller incorporation on the electromechanical properties of ionogel, are also elaborated. Finally, a primer is provided on the application of ionogels in sensors and energy harvesting technologies.

In this work, we investigate the effect of morphology and segmental dynamics on ion transport in polymerized lyotropic liquid crystals (polyLLCs) containing 1‐butyl‐3‐methylimidazolium tetrafluoroborate as ionic liquid (IL). We demonstrate that two important factors, which affect ion conduction in polyLLCs, are grain size and chain density at the interface. The polyLLC with large grain size (70 nm) shows significant reduction in ion conductivity (one order of magnitude) compared to its homopolymer/IL mixture. However, the polyLLC with small grain size (20 nm) has little difference in ion conductivity compared to its homopolymer/IL mixture. It is observed that decreasing the chain density enhances the interaction of IL with polymer chains and consequently slows the relaxation of polymer chains. In addition, comparing the dynamics of polymer chains in mixtures of homopolymer/IL and templated LLC mesophases shows that the confinement in LLC structure prolongs the relaxation of polymer chains.
