A Study in Electrochemical Performance of Perovskite based Energy Storage Systems
Abstract (300 words maximum)
With energy demands increasing globally, robust energy storage devices like supercapacitors are becoming integral part for providing reliable energy storage. The material morphology of such devices dictates their properties and efficiency. Perovskites, with a general structure of ABX3, where A is cation, B is anion, has shown great potential for supercapacitor electrodes due to its stability, and its ability to exhibit high electrical conductivity. In this work, we study the electrochemical performance of strontium-based perovskites LaSrMnOx and their role in energy storage applications. Electrodes were synthesized using solid state synthesis at 900C and the performance of LSM electrodes was assessed using electrochemical methods such as cyclic voltammetry (CV), impedance spectroscopy (EIS), and galvanostatic charge-discharge (GCD) to provide insight on its electrochemical properties. The results generated will provide a better understanding into the specific capacities, and charge discharge behavior of the electrode, along with ohmic, non-ohmic, and Warburg resistances.
