Highlights

  • Deep eutectic solvents (DESs) are alternative green solvents.

  • DESs ion gels composite of DES as solvent or crosslinker.

  • DES ion gels own good electrical conductivity, stability, and environmental friendliness.

Abstract

Deep eutectic solvents (DESs) have received widespread attention for their advantages of good electrical conductivity, stability, environmental friendliness, and easy preparation with a wide range of applications. However, it was not until recent years that DESs were used as gel electrolytes as environmentally friendly alternatives to ionic liquids (ILs). In this review, we first introduce the DESs related eutectogels (or ion gels), then introduce the types and applications of the gels, the opportunities and challenges of them are also summarized.
