Template‐Directed Synthesis of Pillared‐Porous Carbon Nanosheet Architectures: High‐Performance Electrode Materials for Supercapacitors

3D pillared-porous carbon nanosheets with supporting carbon pillars between the carbon layers is prepared by the carbonization of pitch on porous MgO templates. This unique structure endows the high-rate transportation of electrolyte ions and electrons throughout the electrode matrix, resulting in excellent electrochemical performance.
