摘要

This study presents a porous plate-like CoMn2O4/rGO nanocomposite with enhanced electrochemical performance as a positive electrode for asymmetric supercapacitor applications. The integration of reduced graphene oxide nanosheets within CoMn2O4 nanoplates increases porosity and electrical conductivity, contributing to a high specific capacitance of 1680 F g⁻1 significantly higher than that of bare CoMn2O4 (1390 F g⁻1). The assembled asymmetric supercapacitor achieves an energy density of 53.3 Wh kg⁻1 and a power density of 798 W kg⁻1 at 1 A g⁻1, along with excellent cycling stability, retaining 95.5% capacitance after 10,000 cycles. These results demonstrate the effectiveness of the composite architecture in advancing high-performance energy storage systems.
