In this investigation, Co3O4 nanospheres are prepared at 200 °C using the combustion method and then annealed at 600 °C. Microstructural and electrochemical properties are measured in order to investigate nanostructured Co3O4 samples as prospective electrode materials. XRD spectra of all samples showed (220), (311), (222), (400), (422), (511), and (440) orientations, indicating Co3O4 in cubic structure with space group of Fd 3̄ m (227). Raman tests confirmed the existence of Co-O bonds and microstructure of the samples. Scanning Electron Microscopy examination demonstrates the materials' nanosphere-like form. XPS spectra demonstrate the existence of Co+2 and Co+3 with O-2 in a spinel configuration. The BET and BJH analyses demonstrate the type IV isotherm and the H3 hysteresis loop of as produced nanospheres of Co3O4. The electrochemical performance of Co3O4 nanospheres were examined in a 1M KOH aqueous electrolyte, and it was found that the as-prepared sample had the maximum capacitance of 209 Fg-1 at 1 Ag-1 current density as well as greater electrochemical stability even after 2000 cycles.

Superior reaction reversibility of electrode materials is urgently pursued for improving the energy density and lifespan of batteries. Tin dioxide (SnO2) is a promising anode material for alkali‐ion batteries, having a high theoretical lithium storage capacity of 1494 mAh g− based on the reactions of SnO2 + 4Li+ + 4e− ↔ Sn + 2Li2O and Sn + 4.4Li+ + 4.4e− ↔ Li4.4Sn. The coarsening of Sn nanoparticles into large particles induced reaction reversibility degradation has been demonstrated as the essential failure mechanism of SnO2 electrodes. Here, three key strategies for inhibiting Sn coarsening to enhance the reaction reversibility of SnO2 are presented. First, encapsulating SnO2 nanoparticles in physical barriers of carbonaceous materials, conductive polymers or inorganic materials can robustly prevent Sn coarsening among the wrapped SnO2 nanoparticles. Second, constructing hierarchical, porous or hollow structured SnO2 particles with stable void boundaries can hinder Sn coarsening between the void‐divided SnO2 subunits. Third, fabricating SnO2‐based heterogeneous composites consisting of metals, metal oxides or metal sulfides can introduce abundant heterophase interfaces in cycled electrodes that impede Sn coarsening among the isolated SnO2 crystalline domains. Finally, a perspective on the future prospect of the structural/compositional designs of SnO2 as anode of alkali‐ion batteries is highlighted.
