Electrochemical capacitors : A hierarchical porous graphitic carbon material, composed of macroporous ion‐buffering microreservoirs, ion‐transporting channels, and localized graphitic wall structures, is presented (see images; top: 3D skeleton, bottom: carbon platelet). The properties of this new material combine to overcome the electrode kinetic problems normally found in electrochemical capacitors, thus resulting in an excellent high‐rate energy‐storage performance.
