Normally, capacitive charge storage aligns with the principles of dielectric or electrolytic capacitance, which is non-faradaic in nature; however, in the case of batteries, faradaic processes dominate for non-capacitive charge storage. Due to the complex nature of compost, the type of compost and the type of current collectors have been varied while using distilled water as an aqueous media, and the investigation in this work encompasses both capacitive and non-capacitive processes in a symmetric dual current collector device to delineate and discern the diverse charge storage mechanisms inherent to capacitors and batteries. Test cells have been optimised with respect to volume, distance between the current collector, and variation in applied current; following that, optimised test cells have been analysed using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) studies and electrochemical impedance spectroscopy (EIS) to study non-faradaic and faradaic processes in terms of charge storage capability, charging and discharging time, specific capacitance, and specific capacity. To observe the role of microorganisms in the compost, autoclave studies using the best compost sample (baked at 120 °C for 60min) have also been performed. In addition, chrono-amperometry studies have been performed to investigate the stability of the device.
