▎ 摘　　要

Graphene composite with carbon nanotube is one of promising active materials for energy storage applications. Herein, the N-doped reduced graphene oxide/reduced multi-walled carbon nanotube oxide (N-rGO(ae)/r-MWCNTO) composite was inspirationally introduced as the negative electrode material for the lithium hybrid capacitors (LICs). The negative electrodes of the N-rGO(ae)/r-MWCNTO composites with respective to Li/Li+ initially deliver ca. 1500-2900 mAh g(-1) at 0.1 A g(-1) for which the electrode consisting of 50:50 wt% of N-rGO(ae):r-MWCNTO finely tuned provides the maximum specific capacity with a cycling stability over 500 cycles with 100% coulombic efficiency. In addition, the full cell of 50:50 wt% N-rGO(ae)/r-MWCNTO//activated carbon (negative electrode//positive electrode) provides a voltage window of 2.0-4.0 V, an impressively maximum energy density of 189.90 Wh kg(-1) and a power density of 24105 W kg(-1) based on the active materials from both electrodes. As a result, this device may be useful for high energy and power applications. (C) 2019 The Electrochemical Society.
