“…With the rapid advancement of smart and wearable electronic products, human society is demonstrating an increasing demand for high-performance flexible energy storage devices, particularly miniaturized flexible supercapacitors that are lightweight, have a high capacity, can charge quickly, and have a long cycle life. − Electric double-layer capacitors (EDLCs), pseudocapacitors, and hybrid capacitors are three categories of supercapacitors that can be distinguished based on the energy storage mechanism of the Faraday reaction. , The performance of supercapacitors is greatly influenced by the materials used for the electrodes and electrolytes. , Therefore, to fabricate supercapacitors with high power density and high energy density, it is necessary to develop novel electrode materials, electrolytes, and innovative device configurations . The commonly used electrode materials for supercapacitors include carbon materials [activated carbon, carbon nanotubes (CNTs), graphene, carbon fibers, and carbon aerogels], transition-metal oxides (RuO 2 , MnO 2 , IrO 2 , NiO, Fe 2 O 3 , Co 3 O 4 , and V 2 O 5 ), conductive polymers [polypyrrole, polythiophene, and polyaniline (PANI) , ] and their various composites. − Electrode materials made of carbon display the typical behavior of an EDLC.…”
