Abstract

The development of supercapacitors with high energy density, stability, and a wide range of operating potential is an urgent issue. To satisfy the required enhancements on supercapacitor modules, new-generation electrode materials need to be designed. In this study, B4C-BN nanocomposite powder is proposed as a novel electrode material. Nanocomposite powders were synthesized via cost effective sol-gel technique and processing conditions were optimized to tailor phase ratio, particle size, and morphology. The phase composition of synthesized powders was characterized by XRD. The morphology of the particles was examined by SEM and HR-FESEM techniques. The electrochemical performance of electrodes was investigated by using CV. The results indicate that particle morphology, size, and the ratio of B4C/BN phases have a considerable impact electrochemical performance of fabricated electrodes.
