“…5b shows the electrostatic potential (ESP) and the distribution of the Mulliken charge. 27 It is found that the Mulliken charges of the DES changed noticeably before and after the HCl participation. By interacting with HCl, the Mulliken charge of the nitrogen atom (–NC–) shifted from −0.190 to 0.145, and the chlorine atom was also greatly affected and became more negative (−0.178 vs. −0.811).…”

Storage of energy is essential to meet the daily demand for powering portable devices. This necessitates the development of storage systems such as supercapacitors (SCs), batteries, and solar cells. SCs have garnered a lot of attention for their ability to provide a massive amount of power. Nevertheless, traditional mechanisms fall short of our expectations. Ionic liquids (ILs), the evolutionary green designer solvents, are efficient enough to substitute for conventional electrolytes such as aqueous or organic electrolytes in SCs. A limited potential window of aqueous electrolytes restricts the performance of high energy electrodes. In contrast, organic electrolytes with high volatility, flammability, and lack of tunability are not suitable for long-term and robust applications. Beneficial properties of ILs such as negligible volatility, high thermal, chemical, and electrochemical stability have overcome many restrictions in SCs and improved their overall performances. ILs can be used as standalone electrolyte or can be mixed with organic electrolytes, redox elements, and polymers to obtain electrolytes for SCs. The structure of anions and cations has been found to significantly influence overall electrochemical performances. ILs benefit SCs with a wider working voltage, temperature range, and better energy density. ILs have been utilized not only as electrolytes but also in the synthesis of electrode materials. Consequently, it is essential to discuss recent findings and the function of ILs in achieving higher-performing SCs. This review mainly highlights the most recent findings on the use of ILs-based electrolytes and electrodes in supercapacitors.

“…For instance, Xu et al increased electrode wettability and subsequently reduced internal resistance by adding anionic surfactant ILs [C 4 C 1 pyr][AOT] to the [C 3 C 1 pyr][Tf 2 N] electrolyte. Xiong et al synthesized a novel mixed anion, [PTSNTF] − ( p -tosyl(trifluoromethyl)sulfonimide), which exhibited an electrochemical window of up to 5.3 V when combined with the typical ion [C 4 C 1 pyr] + in the electrolyte. In summary, these studies demonstrate the potential of employing new functional groups or novel ionic liquids to optimize the performance of EDLCs in terms of internal resistance and electrochemical voltage.…”

Ionic liquids (ILs) consisting entirely of ions exhibit many fascinating and tunable properties, making them promising functional materials for a large number of energy-related applications. For example, ILs have been employed as electrolytes for electrochemical energy storage and conversion, as heat transfer fluids and phase-change materials for thermal energy transfer and storage, as solvents and/or catalysts for CO2 capture, CO2 conversion, biomass treatment and biofuel extraction, and as high-energy propellants for aerospace applications. This paper provides an extensive overview on the various energy applications of ILs and offers some thinking and viewpoints on the current challenges and emerging opportunities in each area. The basic fundamentals (structures and properties) of ILs are first introduced. Then, motivations and successful applications of ILs in the energy field are concisely outlined. Later, a detailed review of recent representative works in each area is provided. For each application, the role of ILs and their associated benefits are elaborated. Research trends and insights into the selection of ILs to achieve improved performance are analyzed as well. Challenges and future opportunities are pointed out before the paper is concluded.
