Research progress on deep-eutectic-solvent-based ionic gels for energy storage

Abstract As the energy crisis and environmental pollution problems become increasingly prominent,the demand for green and efficient energy storage devices is becoming urgent. Therefore, it is very important to select green materials which are environmentally friendliness, safe and easy to synthesize in energy storage devices. Deep eutectic solvents (DESs) are often used as plasticizers in ionic gels because of non-flammablity, non-volatility, low-cost and biodegradability. Ionic gels based on DESs are composed of DESs and gelators (linear polymers, polymer networks, supramolecular networks, etc.). They are simple to prepare, have excellent physical and chemical properties, and meet the demands of green chemistry. What is more, they take advantage of DESs and gelators, have different functions (ionic conductivity, pH-responsiveness, self-healing performance, etc.). Finally, the practical applications of deep-eutectic-solvent-based ionic gels in energy storage are summarized, and their development in the future is prospected.
