dc.description.abstract | Three-dimensional (3D), binder-free, porous carbon-based electrodes exhibit high charge storage ability in electrical double-layer capacitors owing to their well-developed porous structures enhancing mass transfer and achieving relatively high electroconductivity. A 3D N-doped carbon electrode with abundant oxygen-containing functional groups was prepared by depositing a PDA-derived N-doped carbon layer and electrochemical oxidation using a porosity-regulatingin situgenerated Cu2O sacrificial template. The optimized electrode demonstrated a high specific capacitance of 2852 mF cm−2at a current density of 1 mA cm−2and good rate capability. The material was used as an electrode in a symmetric capacitor, exhibiting an energy density of 16.4 mW h cm−3at a power density of 180 mW cm−3, which maintained 89% of its value after 15 000 cycles. This study describes a new method of manufacturing high-performance porous electrodes suitable for practical application in electric double-layer capacitors. | en_US |
