【 摘 要 】

tsA surface engineering strategy was proposed to design hierarchically porous structure on fibrous carbon cathodes with O/N heteroatom functional groups.High-energy and anti-self-discharge Zn-ion hybrid supercapacitors (ZHSs) were realized.ZHS electrochemistry was investigated and new insights were provided.
