Textile carbon network with enhanced areal capacitance prepared by chemical activation of cotton cloth

Structural design and mechanism analysis of hierarchical porous carbon fibers for advanced energy and environmental applications

“…Theoretically, almost all natural biomass can be carbonized into carbon with unique structures and natural porosity; however, only natural fibers with well-organized structures lead to PCFs. These fibers include cotton, 110,128–132 sisal, 133 jute, 134 silk, 135 bamboo, 136 fungi, 137 collagen, 109,138 and bacterial cellulose. 139 For example, Yang et al produced activated PCFs with a large amount of surface defects through the carbonization of cotton fibers followed by activation with KOH.…”

A sustainable one-step strategy for highly graphitized capacitive carbons with hierarchical micro–meso–macro porosity

“…Carbon-based electric double-layer capacitors (EDLCs), as a sustainable and efficient energy storage device, have drawn extensive attention owing to their unique advantages, including fast charge-discharge, high power density, simple principle, long cycle life and environmental friendliness. [1][2][3][4][5] Energy storage of EDLCs arises from the pure electrostatic charge accumulation on the surface of electrodes. Based on such a charge storage mechanism, the surface properties and pore structure play a vital role in determining the electrochemical capacitive performance of carbon-based EDLCs.…”

Paper-based triboelectric nanogenerators and their applications: a review

“…Recently, they have also been applied in various energy-related devices [66][67][68]. Although paper is intrinsically insulating, conductive materials (e.g., metal nanowires, con-ducting polymers, carbon nanotube (CNT) inks, multiwall carbon nanotube (MWCNT) inks, and reduced graphene oxide) [69][70][71][72][73][74][75][76][77][78][79][80][81][82], can be easily absorbed or used as a coating layer on the surface of the paper due to its wettability and moisture-retention capacity. This provides an efficient method to prepare paper electrodes for TENGs.…”
