Redox-active binary eutectics: Preparation and their electrochemical properties

Eutectics are emerging as promising candidate for electrochemical energy storage. However, the eutectics usually show high viscosity that usually arises from strong intermolecular interactions greatly limits their application. In this communication, we design and prepare two redox-active molecules t...
