Abstract

Transition metal-based spinel oxides have become attractive materials for supercapacitor electrodes because of higher specific capacitance (C_s) and low cost. Nonetheless, spinel materials have limited stability because of small interfacial area. Carbonaceous electrode materials like rGO mitigated this problem by enhancing the electroactive surface area and increasing the active sites. This study employed hydrothermal synthesis to fabricate NiBi₂O₄/rGO (NBO/rGO). The materials potential as electrodes was evaluated utilizing 3-electrode configuration and several electrochemical techniques to evaluate the attributes of NBO and NBO/rGO. The fabricated NBO/rGO demonstrates C_s of 1104.87 F g⁻¹ at 1 A g⁻¹ also remarkable stability over the 3000^th cycle and energy density (25.79 Wh kg⁻¹). Electrochemical studies indicate that rGO enhances the overall stability of NBO by prolonging the discharge time interval, hence boosting the C_s. This study demonstrates that rGO can enhance the performance of NBO in various energy-storing systems.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
