摘要

A composite of nickel-doped cadmium stannate (Cd1−xNixSnO3) was prepared utilizing a hydrothermal approach. The CNS0.0, CNS0.2, CNS0.4, CNS0.6, and CNS0.8 samples were produced with different concentrations of Cd1−xNixSnO3 composites, where x = 0.0, 0.2, 0.4, 0.6, and 0.8, respectively. The effect of different degrees of Ni2+ ion doping on the electrochemical, structural, and morphological properties of the composite nanoparticles was investigated using a variety of characterization techniques. From electrochemical tests, the specific capacitance of the CNS0.6 sample was recorded at 557.61 F/g at 0.2 A/g, which is an improvement over the pure sample, when Ni2+ ions are substituted. After 2000 cycles, the CNS0.6 electrode retained 90.1% of its capacitance, proving the reliability and longevity of electrical components in practical settings. The improved structural characteristics, higher redox activity, and enhanced ionicity brought about by the insertion of Ni2+ ions are believed to be responsible for this enhanced performance.
