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

Abstract Aqueous zinc ion batteries (AZIBs) are thought to be emerging energy storage systems due their features with high safety, low cost, and eco‐friendliness. They possess potential applications in smart grids wearable devices. However, it is still a challenge design suitable cathode materials that matches well anode. Herein, graphene oxide (GO) coated VO 2 nanobelts prepared through facile hydrothermal route. The Zn//VO @GO deliver specific capacity of 323 mA h g −1 at current density 0.1 A . It maintains an 88% retention rate 5 after 1000 times cycling. Moreover, the assembled flexible cells demonstrate excellent mechanical stability under different folding conditions.
