Bacterial cellulose/carbon nanotube/manganese dioxide composite electrode for flexible supercapacitors

Popis výsledku v původním jazyce

Nowadays, urge for the development of portable electronic devices has been increased as well as demand for high-performance based energy-storage systems, which are lightweight, ultra thin, flexible, and wearable [1]. Supercapacitors (SCs) are such an important energy storage device that has attracted significant attention because of their higher power density, cycle efficiency, and charge-discharge rates as against batteries [2]. However, conventional SCs are too heavy, rigid, and bulky to meet the practical requirements due to the employment of inactive components, including current collector, binder, and conductive additives [3]. Therefore, there is an urgent need to develop flexible SCs with high performance. However, flexible SCs require an efficient electrode materials to possess good electrical, mechanical and electrochemical properties, without dramatic degradation of performance during their deformation. Applying an active electrode materials like carbon nanotubes (CNTs), metal oxides as well as conductive polymers, into various flexible substrates, such as plastics, textiles, and papers, are able to fabricate flexible electrodes for SCs [4]. Bacterial cellulose that composed of cellulose nanofibers exhibits different properties from conventional flexible substrates due to its highly porous structure. A large amount of functional groups on the surface of cellulose nanofibers is beneficial for capturing active electrode materials. Moreover, it has specifically high tensile strength and Young's modulus despite of high water-holding capacity [5]. Therefore, bacterial cellulose could be a good substrate on which to fabricate lightweight and flexible composite flexible electrodes for supercapacitors. immerging-pressing process and using BC as a substrate, finally a high flexible composite electrode was accomplished. Thereafter, one SC was assembled by these electrodes and investigated which are reported in this paper.
