Abstract

Abstract: The conversion of biomass waste into functional carbon materials is an environmentally friendly solution with diverse applications for a sustainable world. Here, we report an approach to fabricate the Ganoderma Lucidum waste-derived erythrocyte-like N, O self-doped porous biomass carbon (GL800) with a high graphitization degree by a facile carbonization and activation method. The prepared GL800 showed a relatively high specific surface area (2407.5 m 2 g −1 ) and a porous structure like the red blood cell, which affords enough space to accommodate active sites and are easy for electrolytes to infiltrate. Due to the synergistic effect of the rich N, O self-doped elements and porous structures, GL800 shows strong chemical adsorption and physical confinement for polysulfide. Lithium-sulfur batteries using GL800 electrodes exhibited a high discharge capacity of 1367.8 mA g −1 at 0.1C and desirable rate performance. Furthermore, the battery has a capacity retention rate after 300 cycles at 0.5C with high coulombic efficiency (99%). Together with the good biocompatibility and biodegradability of the prepared material, it has a high potential for diverse applications in energy storage, environmental remediation, wearable electronics, biomedicine, and other areas, providing a Nature-derived solution with good sustainability. Graphical abstract: The reasonable conversion of biomass waste into functional carbon materials is an environmentally friendly and sustainable choice for processing biological waste. An erythrocyte-like N, O self-doped porous biological carbon (GL800) with high specific surface area (2407.5 m 2 g −1 ) and high degree of graphitization is fabricated. As a result, lithium-sulfur batteries assembled with GL800/S cathode exhibit excellent electrochemical performances, including a high discharge capacity of 1367.8 mA g −1 at 0.1C and a desirable rate performance. Furthermore, the battery has a capacity retention rate of 72.3% after 300 cycles at 0.5C with high coulombic efficiency (99%). This work is environmentally friendly and shows a great potential for practical applications of biomass carbon material in energy, catalysis, biomedical and other related fields. Image 1
