Asymmetric Supercapacitors NP-MnO2// P-MXene/CPAQ-A Device in Aqueous Electrolyte with a Wide Voltage Window, Good Mechanical Flexibility, and High Circle Stability
This study presents the development of an asymmetric supercapacitor (ASC) utilizing NP-MnO_2 as the positive electrode and P-MXene/ "C" _"PAQ" -A (PAQ: quinone-amine polymer) as the negative electrode. This combination enhanced energy and power density by combining pseudocapacitive and electrochemical double-layer mechanisms. Characterization and electrochemical analysis reveal superior performance, including a wider voltage window (1.9V) and extended cycle life, positioning this kind of ASC as a promising solution for advanced energy storage applications. Environmental impact is minimized using water-based electrolytes.
