Fabrication of enhanced electrochemical AlBiO3/g-CN nanocomposite electrode material via hydrothermal approach for supercapacitor applications

Abstract

The fundamental discrepancy in energy produced from renewable sources indicates that there is a persistent mismatch between the supply and demand of energy. Researching and developing appropriate materials for employing energy-storing devices is an efficient approach to resolving this recurring issue. Using a hydrothermal preparation technique, AlBiO3 and AlBiO3/g-CN nanocomposites are produced in this work. Galvanostatic charge/discharge (GCD) analysis at 1 A g−1 were used to determine the specific capacitance (Cs) value for AlBiO3 and AlBiO3/g-CN which were 888 and 1508 F g−1, respectively. Over 10000th cycles, the AlBiO3 and AlBiO3/g-CN showed outstanding performance and outstanding cycling stability. The synergistic association between AlBiO3 and g-CN generated higher specific surface area (SSA) and extra active spots for higher charge transfer with less impedance. The outcomes of the electrochemical investigation exposed that the AlBiO3/g-CN composites architecture performed more effectively than the AlBiO3, suggesting that it is useful structure for energy-storage devices. Further, symmetric investigation was also confirmed that AlBiO3/g-CN nanocomposite promising electrode material for practical application.
