Therefore, the increased SBET of 622 m 2 g -1 and pore volume of 0.83 cm 3 g -1 along with the doped boron as well as oxygen containing functionalities at higher temperature are believed to be responsible for the higher capacitance performance by the BG-800. The enhanced capacitance offered by the BG-800 is too reflected from the severe non-linear GCD profile as clearly exhibited in Fig. . In another literature, the B-doped graphene nanoplatelets was prepared by the freeze drying of the suspension of GO and boron oxide accompanied by thermal annealing at four various temperatures in N2 atmosphere for (997 m 2 g -1 ) is lower than that of BMG-c (1102 m 2 g -1 ) suggesting the increased EDLC behaviour and the reduced pseudocapacitance for the latter one. and GO has attained the highest the specific capacitance of 406 F g -1 at 2 A g -1 in 1M H2SO4 solution and displayed a higher capacitance retention of 114% over 5000 cycles at 10 A g -1 .
