ABSTRACT The electrochemical performance of La‐doped synthesizes via a conventional solid‐state reaction method; this was investigated under externally applied magnetic fields in this study. Electrochemical techniques, including cyclic voltammetry (CV), galvanostatic charge–discharge (GCD) and electrochemical impedance spectroscopy (EIS), are performed in both the absence and presence of magnetic fields ranging from 200 to 800 G. A notable enhancement in specific capacitance was observed at an applied field of 800 G, with an increase of 60.03%, from 34.83 to 55.74 at a current density of 0.3 . This enhancement was attributed to magnetohydrodynamic (MHD) effects, which promote improved ion transport and charge transfer within the electrode–electrolyte interface. The results demonstrate that the application of an external magnetic field is an effective approach for enhancing the electrochemical behavior of pseudocapacitive materials. These findings suggest that La‐doped is a promising candidate for use in advanced supercapacitors and other energy storage applications.
