N, B, and S heteroatom-doped laser-induced porous PES-derived graphene for high-performance supercapacitors

Key Points

• The aim is to develop high-performance supercapacitors using NBS heteroatom-doped graphene composite electrodes.
• Utilized a laser-direct writing technique to create composite electrodes.
• Focused on the incorporation of nitrogen, boron, and sulfur heteroatoms into graphene structure.
• Achieved an areal specific capacitance of 240 mF cm −2 at a current density of 0.5 mA cm −2.
