Recently, studies on miniaturized and flexible electronic devices including artificial skin, smart textiles, and flexible/ wearable electronics are increasingly emerging because of the urgent demand of next-generation high-performance electronic devices[l, 2]. Thus, the study of flexible fibrous supercapacitors (FFSCs) is attracting much attention. Fibrous supercapacitors usually range from micrometers to millimeters in diameter, with the small size and light weight making them suitable for many innovative applications [3, 4]. High electrochemical performance and mechanical reliability are two important properties of flexible fibrous supercapacitors (FFSCs) used in portable and wearable electronics. Herein, we introduce high-performance and stable FFSCs produced using Tetrapanax papyrifer (Tong Cao, TC) with a honeycomb-like structure, the key material, acting as a frame for activated carbon (AC) coating. The honeycomb-like structure facilitates penetration of electrolytes and electron transport in the AC particles. This reduces the contact resistance between the AC and current collector, thereby enhancing the electrochemical energy storage_ In addition, our main materials are all derived from natural resources, and the research themes are in line with SDGs Goal 7 (Ensure access to affordable, reliable, sustainable and modern energy for all) to further provide affordable energy and promote access to research, technology and investments in clean energy.
