Nickel-doped TiO₂ nanoparticles for supercapacitor applications have been synthesized using a solution-based process. The nanoparticles were characterized using X-ray diffraction to confirm the phase and structural modifications induced by nickel doping. The morphology of the synthesized Ni-doped TiO₂ nanoparticles was investigated using a scanning electron microscope. Electrodes were prepared on stainless steel substrates via a drop-casting and drying process, incorporating the doped nanoparticles. The fabricated devices were subjected to electrochemical performance analysis, including cyclic voltammetry and electrochemical impedance spectroscopy. Electrochemical results indicate enhanced capacitive behavior due to nickel doping, highlighting the potential of Ni-doped TiO₂ nanoparticles as promising candidates for next-generation supercapacitor applications.
