Abstract: Lithium-ion batteries have help revolutionized the industry. Advancements in energy storage technologies have helped to put LIBs in several household appliances and day-to-day systems and machines, as well as to spur the growth of new industries like the Electric Vehicle industry. In recent years, the discovery of NVOPF as a possible material for a cathode in a LIB system has sparked much excitement, largely due to the favourable electrochemical properties of NVOPF. Indeed, recent studies of NVOPF have discovered high reversible capacities, excellent cycling life, high energy densities and a low cost of manufacturing. Furthermore, the discovery of Graphene Quantum Dots as an additional component to LIB cathodes is also sparking new research areas. The physical and electrochemical properties of GQDs, including their biocompatibility and strong luminescence make them great candidates, and the various possible methods to obtain them make it easy to produce GQDs of specific desired characteristics. In this paper, we compare and contrast the difference in battery performance when we use NVOPF as a cathode, against using NVOPF with GQD as a cathode material. We compare the two cathodes across battery performance metrics such as cycle rate, CV and charge and discharge performance, using EIS.
