Energy demand has become a persistent concern and high‐performance energy storage systems have increasingly undergone development. Supercapacitors and batteries pose great impact on energy storage and garner a great deal of attention from technologies and researchers alike. The performance of energy saving devices is primarily determined by the electrode material in terms of high specific capacitance, excellent conductivity, remarkable natural abundance, and unique electrochemical qualities, also large surface area. Cobalt (Co)‐based materials are unique electrode materials widely used in energy storage devices. Nevertheless, a combination of Co and ferrite materials such as nickel, zinc, and copper, or Co/nonferrite materials like metal–organic frameworks and layered double hydroxides has improved their ultimate efficiency. This review deals with energy storage applications of Co‐based materials, categorizing ferrites, their electrochemical characterization, performance, also design and manufacturing intended to supercapacitors and batteries applications. Summarizing the main outcomes of the literature on batteries and supercapacitors, energy storage systems comprising Co‐based materials combined with carbon nanotubes, graphene, silica, copper, zinc, nickel, cadmium, ferrous, and lanthanum are reviewed and discussed. Lithium‐ion batteries are investigated specifically, and perspectives on Co‐based ferrite development for future generations of supercapacitors and batteries are outlined.

Novel electrode materials with unique architectures are always favored to improve the capacity and energy density of supercapacitors. Herein, we have designed a composition of transition metal and reduced graphene oxide (rGO) as advanced electrode for enhanced‐performance supercapacitors. Particularly, a facile one‐pot hydrothermal approach was applied for in‐situ growth of NiCo/rGO composite. It displayed the best electrochemical performance attributing to the three‐dimensional flower‐like architecture in combination with conductive rGO. Among all the electrodes, NiCo/rGO exhibited impressive areal capacitance of 2565 mF/cm2 at a current density of 1 mA/cm2, and a high energy density of μWh/cm2 at a power density of 200 μW/cm2. The electrochemical impedance spectroscopy confirms feasible charge transfer kinetics at the interface with small internal resistance and rapid diffusion, resulting an improved electrochemical performance.
