Abstract: In this study, the non-activated N, S-co-doped biochar carbon for supercapacitors were successfully prepared from banana without any activation. In addition, our electrochemical test demonstrated that the as-prepared carbon materials exhibited a high specific capacitance and excellent cycling performance due to the co-existence of N and S.
