“…This aspect deserves close attention because these conformational changes may help to elucidate the mechanization in more detail than experiments can, as well as potentially helping to better explain the energy storage performance of RTIL-based electrolytes. Additionally, the lengths of the nonpolar chains can affect endpoints of the overscreening effect for the ions of RTIL-based electrolytes [ 55 ]. The ions of RTILs can be classified by their overscreening and crowding effects during the charging process, as shown in Figure 5 , where “easier” or “harder” are relative, rather than absolute.…”

Due to the unique properties of room temperature ionic liquids (RTILs), most researchers’ interest in RTIL-based electrolytes in electric double-layer capacitors (EDLCs) stems from molecular simulations, which are different from experimental scientific research fields. The knowledge of RTIL-based electrolytes in EDLCs began with a supposition obtained from the results of molecular simulations of molten salts. Furthermore, experiments and simulations were promoted and developed rapidly on this topic. In some instances, the achievements of molecular simulations are ahead of even those obtained from experiments in quantity and quality. Molecular simulations offer more information on the impacts of overscreening, quasicrowding, crowding, and underscreening for RTIL-based electrolytes than experimental studies, which can be helpful in understanding the mechanisms of EDLCs. With the advancement of experimental technology, these effects have been verified by experiments. The simulation prediction of the capacitance curve was in good agreement with the experiment for pure RTILs. For complex systems, such as RTIL–solvent mixtures and RTIL mixture systems, both molecular simulations and experiments have reported that the change in capacitance curves is not monotonous with RTIL concentrations. In addition, there are some phenomena that are difficult to explain in experiments and can be well explained through molecular simulations. Finally, experiments and molecular simulations have maintained synchronous developments in recent years, and this paper discusses their relationship and reflects on their application.
