For future research, combining the enhanced conductivity of carbon composite cathodes with the nanostructured cathodes and anodes may result in a molybdenum disulfide magnesium-ion battery that operates near the theoretical capacity with good cycling. 2.4. Molybdenum oxide
Further, the discovery of safe, non-corrosive electrolytes for magnesium-based batteries is critical. Cathode materials for magnesium and magnesium-ion based batteries include vanadium oxide, Chevrel phases, Prussian blue, molybdenum sulfide, molybdenum oxide, manganese oxide, and transition metal silicates.
However, the development of magnesium secondary batteries is severely limited by the lack of high-performance cathode materials and the incompatibility of electrode materials with electrolytes.
Molybdenum oxides have been studied less than molybdenum sulfides as electrode materials in magnesium based batteries. Similar to molybdenum disulfide (MoS 2), molybdenum trioxide (MoO 3) forms a double layered structure (Fig. 8).
However, there are still some problems hindering the commercial development of magnesium ion batteries. Due to the high charge density, strong polarization effect and slow diffusion kinetics of Mg 2+, it is still a great challenge to develop positive electrode materials that meet current commercial requirements.
With the recent increase in reports involving cathode materials for magnesium-ion batteries, it is important to assess recent research in order to provide inspiration for future research. Specifically, there are many magnesium-ion studies involving numerous cathode compositions and various phases (Table 2).
