These polarized sites facilitate the interactions with electrolyte ions to enhance chemically active sites and ion adsorption; (ii) Incorporating electron-donor heteroatoms supplements the delocalization of lone-paired electrons in the carbon framework with improved intrinsic conductivity, and high electron density at the Fermi level and results in ultrafast frequency response with the smallest relaxation time, whereas compositing pseudocapacitive materials with carbon, shows the Nyquist plot with higher charge transfer resistance compared to the heteroatom doped carbon ; (iii) Integrating heteroatoms into the carbon structure, do not contribute any additional mass to carbon, whereas combining carbon with pseudocapacitive materials introduce additional mass into the composite, which often results in lowering of specific capacitance while compared to the pristine pseudocapacitive materials ; Embedding pseudo-active heteroatoms can expedite proton adsorption and favor pristine carbons to pursue faradaic pseudocapacitive behavior based on electrochemical redox reactions.
