Compared with typical carbon-based materials, molybdenum-based materials own a much higher specific capacitance, taking advantages of their multiple oxidation states that are in favor of fast charge storage [ 9, 10 ], which are considered as promising electrode candidates for aqueous batteries.
However, molybdenum-based (Mo-based) materials have attracted considerable attention as one of the most promising emerging electrode candidates for rechargeable batteries due to their unique structural and performance advantages .
In this review, we summarize the application of molybdenum-based materials in various kinds of aqueous batteries, which begins with LIBs and SIBs and then extends to multivalent ion batteries such as ZIBs and AIBs. Some new energy storage systems, such as ammonium-ion batteries, are also mentioned.
The well mixed molybdenum oxides at the microscale and the involvement of both mechanisms are considered as the key to the better electrochemical properties. The strategy can be applied to other transition metal oxides to enhance their performance as electrode materials.
Regardless, the enhanced electrochemical performance of molybdenum-based materials would be attributed to the optimized redistribution of electrons caused by the additional introduction of heterogeneous atoms, which impacts the coordination environment of the surrounding atoms in the substrate material.
