- Enhancing quantum capacitance in BNyne/Graphene heterostructures through transition-metal dopants for high-performance supercapacitors
- Abstract
- Using Density functional theory (DFT), we investigated the charge storage capacity, quantum capacitance (CQ), geometry and electronic structures of BNyne/graphene heterostructures (BNyneGHs), as well as the impact of transition-metal dopants on their CQ. Our results showed that doping was more effective than vacancy defects in improving the CQ of BNyneGHs. Ti-doped BNyneGHs exhibited the highest CQ value of 360.08 μF/cm2, making them ideal positive electrode materials for supercapacitors (SCs). The presence of doping agents was found to enhance the density of states (DOS) around the Fermi level, resulting in improved CQ. Our calculations identified potential cathode or anode materials for high-energy-density SCs, providing theoretical support for the design of high-capacitance SCs.
