The salt or salt mixture is heated prior to its melting point to attain a liquid state reaction environment. During this process, precursor molecules are rapidly solvated followed by the subsequent mass transport in the molten salt promote the assembly growth of the two-dimensional eV. The BCN prepared from the variety of precursors using different methods reported in the literature is tabulated in Table . . Among the four various temperatures, the highest specific capacitance of 806 F g -1 in 6 M KOH solution at 0.2 A g -1 was obtained for the BCN obtained at 800 °C and 91% of capacitance was retained from its original value after 3000 cycles at 8 A g -1 . The ravin like morphology of BCN prepared at 800 °C enhances the contact between the electrode and the electrolyte that rises the ion transport that would be the responsible for the improved electrochemical performance. Motivated by the earlier work, the same group developed the boron carbonitride (BCN) by dissolving both the boric acid and 2, 4, 6 tri-(2-pyridyl)-1, 3, 5-triazine in ethylene glycol as a solvent followed by heating with hydrothermal treatment at 250 °C for 24 h and the subsequent thermal annealing at 400 °C for 2 h under N2 atmosphere . The specific capacitance of the prepared material shows the highest value of 343.1 F g -1 at 0.5 A g -1 in 6 M KOH solution with enhanced stability of 90%
