Efficient Charge Storage Characteristics of 2-Dimensional SrCrO ₃ Perovskite based Supercapacitor Electrode

2D functionalized nanomaterials like metal oxides and 2D grown perovskites have emerged as auspicious candidates for electrochemical charge diffusion and storage applications. Integrating the functionality of metal oxide into 2D modeled perovskite has efficiently proved to enhance the pseudo capacitor competence in field of electrochemical energy cycle. SrCrO 3 perovskite fabricated using Sol Gel technique was studied for morphology and electrochemical redox energy storage capacity. The successful synthesis of 2D structural nanoscopic lamellae flakes with nano crystalline size was acknowledged using XRD, SEM, and FTIR. UV was utilized to validate an effective bandgap of 2.4-2.9 eV using absorption characteristics. The substantial potential pseudo-supercapacitive behavior of SrCrO 3 perovskite-Ni foam electrode was analyzed in three electrode setup using 2M KOH alkaline aqueous electrolyte. Duck-shaped CV curve of Sr-Perovskite demonstrated the maximum specific capacitance of 983 Fg -1 at the scan rate of 10 mV/s exposing the pseudocapacitive nature. The GCD exposed specific capacitance of 1618 Fg -1 at a current density of 1 Ag -1 pointed to significant charge storage capability. The electrode proved to be cyclic stable and preserved about 82% of its capacitance even after 40 hrs. These results exhibit Strontium Chromate Perovskite as a noteworthy electrocatalytic nanocomposite material for electrical energy storage.
