Notably, this review extensively discusses reports related to the supercapacitive performance of nitrogen-doped graphene, and similar materials. The electrochemical mechanism governing the interaction between electrolytes, and heteroatoms in N-doped carbon under different conditions is critically analyzed. In contrast, comprehensive mechanistic information regarding the B-doped graphene remains lacking. The incorporation of dopants into various carbon networks give rise to a range of fascinating properties, including wettability, porosity, and improved surface area, which likely contribute to enhanced supercapacitive performance.
