Abstract <p>The developments in the field of material sciences have led to the consideration of magnetic nanocomposites as feasible solutions to the growing global population’s need for better and longer-lasting energy storage devices. This paper reviews the current trends in the use of magnetic nanocomposites for energy storage, by focusing on the unique physicochemical properties of the materials. To provide an overview of the performance of iron oxide and cobalt ferrite in relation to their applications in supercapacitors, batteries, or hybrid systems, using a panel of magnetic nanoparticles. To highlights the methods for controlling the nanoparticle morphology and matrix interaction for enhanced energy storage, as well as the sol–gel and hydrothermal synthesis methods. Magnetic nanocomposites has strategic implications as key materials in future energy storage systems, which should enhance the efficiency of energy storage in the society as well as impact the environment. These prospects are increased charge exchange, high electrochemical surface area and switchable magnetic behaviour making it to overcome current challenges in energy storage. The looming incorporation of these materials into sophisticated devices makes it possible to improve the energy density, power density, and less hazardous influence and that events the direction toward cleaner and more efficient electric power.</p>
