“…Many biomass materials have been used to produce porous carbon with modified surface chemistry not only because of their low cost, natural abundance and high accessibility, but also because of their rich protein contents that can be served as nitrogen and oxygen resource to realize heteroatom doping/co-doping. For example, Chen et al [160] reported a novel honeycomb-like nitrogen and oxygen dual-doped porous carbon (NOPC) derived from soybean residue through a facile carbonization and activation process, which exhibited a special hierarchical porous carbon structure with a large specific surface area of 2690.3 m 2 g −1 , a high pore volume of 1.34 cm 3 g −1 as well as rich N and O co-doping. The superior electrochemical performance of the final NOPC/sulfur composite can be ascribed to the synergistic effects between the hierarchical porous structure and the in situ co-doped N and O elements on carbon surfaces, which can effectively suppress the dissolution of lithium polysulfides via the physical confinement and strong chemical adsorption.…”

Electrochemical energy storage devices, such as supercapacitors and batteries, have been proven to be the most effective energy conversion and storage technologies for practical application. However, further development of these energy storage devices is hindered by their poor electrode performance. Carbon materials used in supercapacitors and batteries are often derived from nonrenewable resources under harsh environments. Naturally abundant biomass is a green, alternative carbon source with many desired properties. This review article presents state of the art of renewable carbon materials derived from natural biomasses with an emphasis on their applications in supercapacitors and lithium-sulfur batteries. IMPACT STATEMENTThis review paper provides a comprehensive understanding for obtaining renewable carbons from natural biomass precursors via various activation methods for electrochemical energy storage application, especially for supercapacitor and lithium sulfur battery.

“…Recently some applications on bean dreg have been reported, such as activated carbon [30], supercapacitor [31]，lithium-sulfur battery [32], however its application in anode for lithium-ion battery has hardly been found. Herein, we report a simple and effective strategy in preparing LIB anode material from bean dregs with pyrolysis treatment at different temperatures and further treatment via graphitization and chemical activation.…”

The KOH-activated sample demonstrated enhanced electrochemical performance due to its high surface area and abundant mesoporous structure. Bean-dreg-derived carbon materials used as superior anode material for lithium-ion batteries AbstractThe structures of modified carbons from bean dregs were regulated via graphitization treatment and chemical activation. The microstructure and electrochemical performance were studied using X-ray diffraction, Raman spectrometer, SEM and TEM techniques. The electrochemical performance was investigated using electrochemical methods. After heat-treatment at 2800 O C, the obtained BDC-2800 possessed a high degree of graphitization and showed an outstanding cycling performance, delivering capacity decay from 423 to 396 mAh g -1 at 0.1 C after 100 cycles. The chemical-treated carbons also demonstrated enhanced electrochemical performance, especially for the KOH-treated sample. The BDC-K displayed superior specific charge capacity of 801 mAh g -1 at 0.1 C, and showed an impressive rate capability of 643 mAh g -1 at 1 C. In addition, this sample delivered capacity retention of 94%after 500 cycles at 1 C. This good electrochemical performance was mainly due to its high surface area and abundant mesoporous structure.

Honeycomb-like nitrogen and sulfur dual-doped hierarchical porous biomass-derived carbon/sulfur composites (NSHPC/S) are successfully fabricated for high energy density lithium-sulfur batteries. The effects of nitrogen, sulfur dual-doping on the structures and properties of the NSHPC/S composites are investigated in detail by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and charge/discharge tests. The results show that N, S dual-doping not only introduces strong chemical adsorption and provides more active sites but also significantly enhances the electronic conductivity and hydrophilic properties of hierarchical porous biomass-derived carbon, thereby significantly enhancing the utilization of sulfur and immobilizing the notorious polysulfide shuttle effect. Especially, the as-synthesized NSHPC-7/S exhibits high initial discharge capacity of 1204 mA h g at 1.0 C and large reversible capacity of 952 mA h g after 300 cycles at 0.5 C with an ultralow capacity fading rate of 0.08 % per cycle even at high sulfur content (85 wt %) and high active material areal mass loading (2.8 mg cm ) for the application of high energy density Li-S batteries.
