| ABSTRACT |
|
Nowadays, a huge increase in the demand for supercapacitor devices has been observed. However, extensive research has been conducted to investigate and develop novel electrode materials to enhance the performance of these devices. However, perovskites and materials based on graphene have shown enormous potential in addressing the world energy issue. Here, the fabrication of perovskite strontium titanium with reduced graphene oxide (SrTiO3@rGO) hybrid was successfully achieved by the hydrothermal approach. For storage purposes, the galvanic charge–discharge (GCD) measurements evaluated a specific capacitance rate of SrTiO3@rGO hybrid 1592.64 F g−1 at 1 A g−1 which demonstrated higher cycling stability over the 5000th cycle. Furthermore, the SrTiO3@rGO hybrid material demonstrates a low internal resistance, as evidenced by a resistance value (Rct) of 0.029 Ω. Our research findings indicate that the synthesis of nanocomposite has demonstrated remarkable efficiency, scalability and cost-effectiveness. These advancements have led to significant enhancement performances particularly in the context of energy storage applications. |
