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.

The synergistic effect between mixed metal sulfides and bimetallic layered double hydroxides (LDHs) is pivotal for their refined energy storage capacities owing to their unique biomimetic-designed 3D Asteraceae flower-like intercalated layered heterostructures. Herein, we report a high-performance MoS 2 / Ni 3 S 4 @NiCr-LDH41 mesoporous heterostructure fabricated via a two-step hydrothermal reaction. This biomimetic-designed 3D Asteraceae flower architecture exhibits a dominant battery type (pseudocapacitance) charge storage mechanism, further authenticated by electrochemical studies. The mesoporous interconnected wall structure offers a colossal specific capacitance of 2323.33 F g −1 at a 0.5 A g −1 current density. Furthermore, the symmetric and asymmetric supercapacitor devices are designed to explore their electrochemical performance. The symmetric assembly exhibits the highest specific capacitance of 111.45 F g −1 at a current density of 1 A g −1 with a capacitance retention of 81.73% over 5000 continuous charge−discharge cycles. It delivers an energy density of 22.29 Wh kg −1 at a power density of 1200 W kg −1 . Markedly, the asymmetric configuration MoS 2 /Ni 3 S 4 @NiCr-LDH41||AC provides the highest specific capacitance of 71.37 F g −1 at 1 A g −1 current density with energy and power densities of 25.37 Wh kg −1 and 800 W kg −1 , respectively, and stupendous electrochemical stability over 10,000 (85.01% capacitance retention) charge−discharge cycles. For the demonstration of real-time applications, two devices are connected in series, which allows the illumination of green LED light for symmetric (90 s) and asymmetric devices (200 s). These favorable outcomes accentuate the magnificent electrochemical performance within the potential and viability of Asteraceae flower−architectured MoS 2 /Ni 3 S 4 @NiCr-LDH41 heterostructure as an electrode material for high-performance supercapacitors.
