Among the popular electrochemical energy storage devices, supercapacitors (SCs) have attracted much attention due to their long cycle life, fast charge and discharge, safety, and reliability. Transition metal oxides are one of the most widely used electrode materials in SCs because of the high specific capacitance. Among various transition metal oxides, Co3O4 and related composites are widely reported in SCs electrodes. In this review, we introduce the synthetic methods of Co3O4, including the hydrothermal/solvothermal method, sol–gel method, thermal decomposition, chemical precipitation, electrodeposition, chemical bath deposition, and the template method. The recent progress of Co3O4-containing electrode materials is summarized in detail, involving Co3O4/carbon, Co3O4/conducting polymer, and Co3O4/metal compound composites. Finally, the current challenges and outlook of Co3O4 and Co3O4-containing composites are put forward.

Unique hollow MoO 2 @C nanoparticles are synthesized in situ by the polyoxometalate-based metal-organic framework as a precursor. Characteristic results show that the prepared MoO 2 @C nanoparticles have a narrow size distribution, and the C, mainly constituted by graphitic carbon, connects with the MoO 2 . Such a special structure guarantees a high electrical conductivity and high chemical stability of the synthesized MoO 2 @C composite material.MoO2@C composite material can provide a high reversible capacity of 1134 mAh g −1 at a current density of 500 mA g −1 after 200 cycles, and has a capacity retention of 88.24%. What's more, while the current density is doubled, the capacity stabilizes at 720 mAh g −1 , of which 81% is retained after 800 cycles. This work highlights that nanostructure design makes contributions to achieving advanced energy storage materials and provides a new concept of preparing organic-inorganic hybrid materials for energy storage.

“…Transition metal oxides (TMDs) are a class of active materials (such as Fe 2 O 3 , Co 3 O 4 , Mn 3 O 4 , and TiO 2 ), who play unique electrochemical mechanisms (including alloying/dealloying, insertion/extraction, and conversion mechanisms) with high theoretical capacity accompanying with the reduction and oxidation of metal during lithiation and delithiation processes . In recent years, we have paid much attention on the studies of various TMDs for LIBs . For example, an Fe 2 O 3 @Mn 3 O 4 nanorod was also synthesized and used for LIB anode, which delivered excellent cycle stability and rate performance.…”

Summary A cross‐linked MnO2 coated ZnFe2O4 hollow nanosphere composite is synthesized and controlled via a facial and handy route. The connected MnO2 nanoplates form a cross‐linked network, which is conducive to the rapid transfer of Li ions. The composite with unique architecture can not only release the strain and stress caused by the insertion and desertion of lithium ions but also greatly improve the electrical conductivity and lithium ion diffusivity. Consequently, when used as a lithium‐ion battery anode material, the electrode shows an excellent initial reversible capacity of 933.5 mAh/g with an initial coulombic efficiency of 62.5%. After 100 cycles, the reversible capacity stabilized at 605.6 mAh/g with a high capacity retention of 91% from the 20th cycle to the 100th cycle. At a high current density of 3 A/g, an excellent capacity of 390.6 mAh/g can be retained. In this case, the electrode shows broad application prospects for novel power storage systems.
