Polyaniline Based Composite Nanostructures on Carbon Cloth for High-Performance Supercapacitor Electrodes

Popis výsledku v původním jazyce

Nowadays, the rapidly developing global economy has caused serious energy and environmental problems which significantly influence the development of mankind. Consequently, exploiting sustainable and clean energy as well as efficient energy conversion and storage technologies is urgently required. Supercapacitors, an important class of energy storage devices, have attracted intensive attention due to their high power capability, ultrafast charge-discharge rate, and long cycle life. However, conventional supercapacitors are too heavy, thick, rigid and bulky to meet the practical requirements for portable, wearable and foldable devices. As such, this is a pressing issue to develop flexible or even foldable supercapacitors, which are strongly dependent on the rational design and innovation of electrode materials. Hence, synthesis of high-performance flexible electrode materials has now become an urgent scientific and technical problem. Herein, a facile strategy has been developed to synthesis of the hierarchical nanocomposite in which ZnO/metal organic framework/polyaniline (ZnO/MOF/PANI) composite nanoarrays deposited on the carbon cloth. The as-prepared ternary nanocomposites facilitate rapid transport of the electrolyte ions and electrons throughout the electrode matrix and reduce the internal resistance of the electrode to result in a high specific capacitance of 340.73 F g-1 at 1.0 A g-1 and a good cycling stability with capacitance retention of 82.49% after 5000 cycles. The formation mechanism and structural control of the hierarchical composites were investigated.
