“…The samples showed a broad peak at 23.6°and a weak peak at 43.5°, which were characteristic peaks of amorphous graphite carbon, indicating that the carbon material had an amorphous graphite structure. Sulfonic acid groups can induce more sulfur species, and these large-sized sulfur atoms create defects in the carbon skeleton and promote the activation process [19,20]. Raman spectroscopy measurement was carried out to further characterize CMS samples (Fig.…”

The spread of COVID-19 has led to an explosive increase in the number of waste polypropylene face masks worldwide, landfill and incineration of which will cause serious pollution and resource waste. This study aims to develop a new method for the safe and high-added value reuse of materials for polypropylene face masks based on carbonization of porous polymer. The waste masks were first sulfonated in an autoclave, then used as carbon source and turned into a dense hollow fiber porous structure after a one-step heat treatment. This porous structure has a high specific capacitance, namely 328.9 F g −1 at a current density of 1 A g −1. Besides, the assembled solid-state capacitor possesses a good energy density of 10.4 W h kg −1 at a power density of 600 W kg −1 , and excellent cycling stability with a capacitance retention rate of 81.1% after 3000 cycles. These findings indicate that the novel carbonization technology in this study can not only be used to obtain high-performance supercapacitor electrode materials but also provide a new idea for the recycling and utilization of wastes such as medical devices.

“…In this regard, sulphonation of lignin was carried out in the presence of NaOH and Na2SO3 to incorporate oxygen enriched C-S-C moiety into lignin based biocarbon (LBB). The as prepared multi porous LBB performed excellent redox activities under in both acidic and alkaline electrolytes with 140 Fg -1 specific capacitance at 0.5 Ag -1 current density [46].…”

“…Oxygen enriched C-S-C moieties are found to be useful for excellent electrochemical performance in carbon-based electrodes, as these moieties decrease the energy gap between valance band and fermi level. Moreover, under high positive potential range, C-S-C moieties prevent the further oxidation of carbon materials and boost up the stability of carbon materials [46]. In this regard, sulphonation of lignin was carried out in the presence of NaOH and Na2SO3 to incorporate oxygen enriched C-S-C moiety into lignin based biocarbon (LBB).…”

“…The carbon electrode from molybdenum disulfide (MoS 2 )-decorated lignin/PAN film by laser direct writing had enhanced areal capacitances up to 16 mF/cm 2 (2.2 F/cm 3 ) and at 10 mV/s [ 196 ]. Chemically modified lignin with sulfonic groups was transformed into porous lignin-based carbon with large SSA (3149 m 2 /g) after carbonization and chemical activation [ 197 ]. The heteroatoms and the graphitic structure had a profound impact on the EC performance.…”

With the increasing demand for high-performance electronic devices in smart textiles, various types of flexible/wearable electronic device (i.e., supercapacitors, batteries, fuel cells, etc.) have emerged regularly. As one of the most promising wearable devices, flexible supercapacitors from a variety of electrode materials have been developed. In particular, carbon materials from lignocellulosic biomass precursor have the characteristics of low cost, natural abundance, high specific surface area, excellent electrochemical stability, etc. Moreover, their chemical structures usually contain a large number of heteroatomic groups, which greatly contribute to the capacitive performance of the corresponding flexible supercapacitors. This review summarizes the working mechanism, configuration of flexible electrodes, conversion of lignocellulosic biomass-derived carbon electrodes, and their corresponding electrochemical properties in flexible/wearable supercapacitors. Technology challenges and future research trends will also be provided.
