“…Metal oxides are preferred as anode materials, because of their pseudocapacitive behavior, different oxidation states, lamellar structure, and very low cost. In [42], V 2 O 5 nanorod@rGO nanocomposite was prepared by sol-gel method using ammonium meta vanadate and citric acid in an aqueous medium. The improved capacitance performance of the V 2 O 5 @rGO composite is primarily endorsed to the rGO; the results showed a high specific capacitance of 289 F/g at a discharge current density of 0.01 A/g, and outstanding cyclic stability with 85% retention of the initial capacitance after 1000 cycles [42].…”

This review article emphases on the modern approaches to the types of sol-gel materials that are beneficial for electrochemistry, monitored by a report of recent advances in the numerous fields of sol-gel electrochemistry. Modified electrodes for sensors and supercapacitors as well as anti-corrosion are described. Sol-gel synthesis expands the capabilities of technologists to obtain highly porous, homogeneous, and hybrid thin-film materials for supercapacitor electrode application. The widespread materials are transition metal oxides, but due to their low conductivity, they greatly impede the rate capability of electrochemical supercapacitors. The way to optimize their properties is the production of complex oxides or different composites. Among the new materials, a special place is occupied by perovskites and materials with an olivine-type structure, which can be easily obtained by the sol-gel method. The sol-gel coating process has demonstrated excellent chemical stability to advance the corrosion resistance of the various metal alloy substrates. Furthermore, the sol-gel process is a user-friendly technique for applying a hybrid sol-gel coating to provide corrosion resistance. The hybrid sol-gel coating technique is the most attractive, easy to prepare at a lower temperature, and has shown the potential to swap Cr-based coatings. The hybrid sol-gel coating has exhibited promising properties of adherent and uses chemically inert to enhance the corrosion resistance of the metal and alloys. Hence, this review article emphases on the recent advances and approaches in the sol-gel coating processes that influence the belongings of its hybrid sol-gel coating for protecting metal substrates and their alloys from corrosion. In addition, the author discusses the current problem and challenges of hybrid anti-corrosion sol-gel coatings. Metal oxides and composites based on them are actively used to create electrochemical sensors. They synthesized, including the anhydrous and citrate sol-gel methods. Such materials are widely used as glucose biosensors and harmful gas sensors.

Current attempts have shown great prospect of substituting lithium-ion batteries (LIBs) with their rival named as Sodium-ion batteries (SIBs), as both share similar chemistry while lithium being scarce and expensive in comparison to the earth crust rich sodium. The poor performance of SIBs anode has restricted its development in the past. Recently, a significant amount of research has been focused on anode materials for SIBs. Carbonaceous anodes have become viable SIB anodes providing high safety, abundant resources, and nontoxicity. In this chapter, the prominent sodium storage capabilities of some potent carbonaceous anodes namely hard carbon, graphite, carbon nanofibers, graphene, biomass derivatized carbon and heteroatom-doped carbon, have been discussed.
