<p>Asymmetric assembly based on the different electrode materials is a common and effective method to obtain high-performance supercapacitors. Herein, we have demonstrated a simple fabrication of asymmetric supercapacitor by using N-doped porous carbon (NC) enhanced PPy and structure-modified Ti₃C₂T_x. The two kinds of reinforced electrodes have been successfully deposited on stainless steel mesh through different fabrication ways. In the 3-electrode system, the obtained specific capacitances of the two electrodes are 386 and 300 F g⁻¹ at 1 A g⁻¹, respectively, and the electrochemical performances are better than those of the pristine PPy and Ti₃C₂T_x. The maximal specific capacitance of the asymmetric device reaches up to 120 F g⁻¹ and remains 68% of the initial value when the current density is raised from 0.5 to 10 A g⁻¹. Compared with the strategy of directly integrating PPy and Ti₃C₂T_x into a hybrid electrode, the above electrochemical findings suggest that assembling asymmetric supercapacitor by using NC-enhanced PPy and structure-modified Ti₃C₂T_x as independent electrodes is an alternative and effective approach.</p>
