Deep eutectic electrodeposition for energy storage and conversion systems. A comprehensive review

Renewable energy storage and conversion systems are vital due to the numerous problems caused by the consumption of fossil fuels. Therefore, research on the emergence of new systems in renewable energies has become one of the most important fields of academic and industrial research. In the meantime, the synthesis of electrodes using the deep eutectic solvent electrodeposition method has many advantages such as being binder-free, creating nanostructured surfaces, and high surface active area has attracted a lot of attention. In this review article, at first, the discussion about the types of electrochemical deposition methods and the mechanism of the deep eutectic solvent electrodeposition process have been discussed, and then the effect of various variables on this process has been discussed. In the following, the use of the electrodes created by this process in new energy conversion and storage systems such as electrocatalysts, batteries, and supercapacitors has been discussed.
