While pristine graphene exhibited pure EDLC behaviour, heavily N-doped graphene exhibited a clear signature of pseudo-capacitive energy storage mechanism. Adequate doping along with enhanced carrier density, can facilitate pseudocapacitive behaviour with higher ED as well as high PD (170 Wh/kg and 8.3 kW/kg).
