High-frequency　responsive　electrochemical　capacitors　(ECs),　which　can　directly　convert　alternating　current　(AC)　to　direct　current　(DC),　are　getting　more　essential　for　the　rapid　development　of　electronic　devices.　In　order　to　satisfy　the　requirements　of　ECs　with　fast　rate　capability　and　appreciable　capacitance　density,　numerous　efforts　have　been　made　towards　the　preparation　and　design　of　the　electrode　material,　which　is　a　decisive　factor　in　the　performance　of　ECs.　Carbon-related　electrode　materials　have　been　widely　shown　to　significantly　increase　the　performance　of　ECs　because　of　their　light　weight,　high　strength,　and　high　processability.　In　this　concept,　the　latest　advances　in　the　rational　design　and　controllable　fabrication　of　carbon-related　electrode　materials,　including　planar　2D　materials,　random　3D,　and　vertical　carbon　materials　are　summarized.　Moreover,　the　state　of　the　art　of　carbon-based　ECs　is　discussed　from　the　viewpoint　of　the　structure　of　the　electrode　and　performance　of　ECs.　Finally,　this　concept　presents　integrated　perspectives　on　the　further　design　and　preparation　of　carbon　related　ECs.　©　2022　Wiley-VCH　GmbH.
