Electron Trapping Ionic Battery Using Graphene and Niobium Coated Electrodes: Simulations and Real Concept

Niobium/graphene-based materials have strong thermodynamic and electrical stability among the present options, ensuring good safety performance for batteries and capacitors. This work demonstrates a prototype ionic battery based on electron trapping by combining computational and experimental approaches. Using EDOs: ode23t technique, a mathematical model was constructed to control the battery's charge/discharge module. We study the electrical and thermal performance as well as the synergic effect of the CVD-coated graphene/niobium electrodes. Electrochemical, XRD, SEM, TEM, and EDS measurements were used to characterize the materials. According to the data, the load cell can charge 2.1 Amperes per minute and discharge completely for a certain amount of time. The electrolyte temperature for both acid and base media is 22°C, and the 140 kV electric field does not cause overheating in the system. Both the graphene oxide and niobium pentoxide-covered electrodes have anode potentials between 1.25 and 1.5, which are comparable to the potentials of platinum and gold.
