Abstract
Metal oxides have attracted growing interest due to their large scale properties and application in various fields. These oxides have exhibited remarkable electrochemical properties. They are not only cheap, friendly to use, easy to synthesize but also are presenting better energy storage efficiency in response to the existing pure metal oxide materials. In this review, we shall try to focus on the importance of energy storage devices, their importance in the current circumstances. This review also includes an introduction about mixed metal oxides and their synthesis using various techniques. Moreover, a simple comparison also has been given. Similarly, an effort also has been made to explain which technique is more beneficial and cost effective presently and similarly ensure green synthesis. Finally, an effort has been made to highlight the applications of these mixed metal oxides in the modern energy storage devices.
Keywords: Mixed metal oxides, electrodes, batteries, capacitors, supercapacitors, conventional methods, microwave methods and energy storage.
