Borocarbonitride‐Based Emerging Materials for Supercapacitor Applications: Recent Advances, Challenges, and Future Perspectives

“…In both studies mentioned above, the synthesized BCN showed a 2D sheet‐like morphology with ample electrochemical active edges, which was fruitful in their supercapacitor performance. [ 36 ] However, the electrochemical performance of Zou et al synthesized BCN 3D network outranked the above studies by replacing the precursors with melamine foam‐derived carbon skeleton, providing higher surface area and as a reservoir for electrolytic ion intake. However, the solvent‐free BCN network was synthesized through two‐step methods: ball milling of B 2 O 3 , dicyandiamide, and polyvinylpyrrolidone and afterward transferring it for pyrolysis at 1050 °C in the presence of H 2 /N 2 .…”

“…This ternary compound is expected to tie the knots of advantages regarding the electrochemical properties of pristine elements in composite form. [36,37] It offers plausible applications in optoelectronics, sensing devices, catalysts, lubricants, supercapacitors, etc. [38][39][40][41] One such ternary nanomaterial is boron-carbon-nitrides (BCN), gaining significant research interest, attributed to its promising traits such as: [42] i) versatility (tuneable structure and composition), ii) thermal and electrical conductivity, iii) chemical stability, iv) excellent mechanical properties, and v) wide bandgap semiconducting applications.…”

A Review on Recent Progress Achieved in Boron Carbon Nitride Nanomaterials for Supercapacitor Applications

“…Another alternative type of electrode material platform for the assembly of BCN-based SCs is 3D nanostructured materials. Compared with 1D and 2D nanomaterials, the infinite growth from 3D features in their spatial structure make 3D BCN-based nanomaterials possess abundant active sites and porous-and-loose characteristics, which is beneficial for supercapacitors with high capacitance performance [118,119]. Tabassum et.al reported a BCNNT architecture entangled on a 3D melamine-foam-derived carbon skeleton with high surface area and hierarchical porosity which displayed a large capacitance of 344 F g −1 at a current density of 1 A g −1 [120].…”

Tailoring NiCoCu layered double hydroxide with Ag-citrate/polyaniline/functionalized SWCNTs nanocomposites for supercapacitor applications

“…As researchers strive to identify the ideal material for supercapacitors, they are increasingly exploring hybrid topologies and synergistic composites to overcome the limitations of individual materials and achieve improved performance metrics. 41 Synergistic composites exhibit enhancements in energy density, power density, and cycle stability. These improvements are achieved by meticulously integrating diverse components possessing complementary qualities.…”
