“…Biomass carbon obtained by anaerobic treatment have become the extremely potential electrode materials for energy storage DOI: 10.1002/smll.202303349 devices because of their easily controlled property, naturally structural diversity, environmental friendliness, and rich sources. [1][2][3][4][5] Generally, biomass precursors, composed of cellulose, hemicellulose, and lignin, play a vital role in the polymorphism of biomass carbon, affecting the graphitization degree of carbon materials. [6][7][8][9] Among them, cellulose derived carbon with parallel hydrogen bond network possesses the remarkable crystallinity for the improvement of electrical conductivity and the reduction of contact resistance between interfaces, and provides an efficiently convenient path for realizing the transmission role of internal electrolyte ions.…”

Conductive biomass carbon possesses unique properties of excellent conductivity and outstanding thermal stability, which can be widely used as conductive additive. However, building the high‐dense conductive biomass carbon with highly graphitized microcrystals at a lower carbonization temperature is still a major challenge because of structural disorder and low crystallinity of source material. Herein, a simple capillary evaporation method to efficiently build the high‐dense conductive ramie carbon (hd‐CRC) with the higher tap density of 0.47 cm3 g−1 than commercialized Super‐C45 (0.16 cm3 g−1) is reported. Such highly graphitized microcrystals of hd‐CRC can achieve the high electrical conductivity of 94.55 S cm−1 at the yield strength of 92.04 MPa , which is higher than commercialized Super‐C45 (83.92 S cm−1 at 92.04 MPa). As a demonstration, hd‐CRC based symmetrical supercapacitors possess a highly volumetric energy density of 9.01 Wh L−1 at 25.87 kW L−1, much more than those of commercialized Super‐C45 (5.06 Wh L−1 and 19.30 kW L−1). Remarkably, the flexible package supercapacitor remarkably presents a low leakage current of 10.27 mA and low equivalent series resistance of 3.93 mΩ. Evidently, this work is a meaningful step toward high‐dense conductive biomass carbon from traditional biomass graphite carbon, greatly promoting the highly‐volumetric–performance supercapacitors.

“…Activated carbons (ACs) are one of the common electrode substances for supercapacitors owing to their cheap and broad surface area. − However, AC often has a poor energy density and low capacitance, severely limiting their practical uses of supercapacitors . Numerous studies have already been done to enhance the capacitance of AC, especially by expanding their volume-to-surface ratio using the electric double-layer energy storage process. ,, By disrupting the conductive networks, the porosity construction diminishes the electrical conductivity of the AC dramatically.…”

Sugar cane bagasse stands as a prevalent and abundant form of solid agricultural waste, making it a prime candidate for innovative utilization. Harnessing its potential, we embarked on a groundbreaking endeavor to evaluate the sustainability of a molasses-based hydrothermal process to produce graphene quantum dots (GQDs). This pioneering initiative promises remarkable environmental benefits and holds immense economic potential. Embedding crystalline GQDs in activated carbon (AC) boost electrochemical efficiency by enhancing charge-transfer and ion migration kinetics. Optical, structural, and morphological evaluations were used to confirm the formation of GQDs. Transmission electron microscopy (TEM) investigation showed the size, shape, and fact that GQDs were monodispersed, and X-ray diffraction and Fourier transform infrared determined the structure of GQDs. The electrodes with negative (AC) and positive (AC@GQDs) polarity demonstrate a considerable specific capacitance of 220 and 265 F g–1, respectively, when measured at 0.5 A g–1. Additionally, these electrodes exhibit high-rate capabilities of 165 and 230 F g–1 when measured at 5 A g–1, as determined by galvanostatic charge–discharge techniques. The supercapacitor device comprising asymmetric AC//AC@GQDs exhibits a specific capacitance of 118 F g–1. Furthermore, the asymmetric device exhibits exceptional cycling behavior, with an impressive 92% capacitance retention even after undergoing 10,000 cycles. This remarkable performance underscores the immense potential of both the negative and positive electrodes for real-world supercapacitor applications. Such findings pave the way for promising advancements in the field and offer exciting prospects for practical utilization.
