Enhanced Supercapacitor Performance through Synergistic BaCO₃ Doping of Graphene Nanoplate Electrodes.

ABSTRACT: Barium carbonate (BaCO₃) is a stable inorganic compound with a high ionic conductivity and thermal stability, making it valuable for electrochemical applications. This study develops BaCO₃-doped graphene nanoplate (GPL) electrodes and compares them to pure GPL electrodes. The BaCO₃/GPL composite exhibits a lower surface area and altered pore distribution but achieves a higher surface potential, enhancing the electrolyte penetration and ion transport. Its superior electrochemical performance makes it a strong candidate for energy storage. Using a 1.0 M Na₂SO₄ electrolyte, Cyclic voltammetry (CV) measurements revealed that at a scan rate of 0.03 V s^-1, the BaCO₃/GPL composite exhibited markedly enhanced capacitance
