| Summary: | Zinc ion batteries (ZIBs) have strong potential for usage as future energy storage technology because of their higher safety, cheaper production costs, and high material availability. Nevertheless, due to a scarcity of good cathode materials, current ZIB performance is still insufficient to meet rising energy consumption. In this experiment, we aim to achieve a porous nanostructure of Vanadium Oxide V2O5 @C; incorporated with Metal Organic Framework (MIL – 47(V)), as the cathode of ZIB battery. We utilized a conventional hydrothermal approach to synthesize MIL-47(V) which was then heated under argon atmosphere to obtain V2O5@C. The resulting ZIB battery performance was compared to that of the commercially used V2O5 cathode battery and excellent results was obtained. The V2O5@C cathode battery achieved a much higher specific capacity, and it can retain 80% of its capacity after 500 cycles, compared to only 26% capacity retention for the commercial V2O5 cathode. The V2O5@C cathode battery also showed better rate performance where it recorded a higher capacity when the current density was varied from 0.2 to 2.0 A g-1. The main reason for these improved characteristics was due to its high porosity nanostructure, which was proven from the SEM result. This V2O5 @C cathode structure has the potential to be used in long-term battery storage applications with high capacity and high-rate capability. Future recommendations include exploring ways on utilizing other types of MOF.
