Renewable and environmentally friendly biomass-based carbon electrode materials naturally possess fast ion transport, high adsorption, and excellent chemical stability for high-performance energy-storage devices. However, intelligently building the effectively biomass-transferred carbon materials for the requirement of high energy density is still a big challenge to date. Here, a hierarchically divacancy defect building platform is reported for effectively biomass-transferred and highly interconnected 3D dual-activated porous carbon fibers (DACFs) based on the internal−external dual-activation function of the pre-embedded KOH and CO 2 molecular. This uniquely interconnected frameworks not only fully provide the abundant active sites for ion interaction, but also efficiently guarantee the substantial accommodation for ion storage. Based on this, the as-prepared DACFs-based supercapacitors deliver a high energy density of 61.3 Wh kg −1 at a power density of 875 W kg −1 in the EMIMBF 4 ionic liquid. This work not only provides a simple and efficient technique to enhance the energy density of carbon materials, but also probably promotes its additional application in environmental remediation.

“…The materials show two broad peaks at 2θ range of 23 • to 30 • and 40 • to 47 • , corresponding to the (002) and (110) crystal plane of graphite materials and it is reflected in all three samples. Generally, all the samples have shown broad peaks around 2θ of 24 • and 44 • , which indicates the typical peaks for amorphous carbon with non-crystalline material structures [42,52,60]. The AC-S-600 sample revealed a high-intensity peak at 2θ = 26.43 • with a hexagonal crystal system of graphite with a d-spacing of 3.370 Å at (002) plane, indicating graphitization.…”

In this work, African maize cobs (AMC) were used as a rich biomass precursor to synthesize carbon material through a chemical activation process for application in electrochemical energy storage devices. The carbonization and activation were carried out with concentrated Sulphuric acid at three different temperatures of 600, 700 and 800 °C, respectively. The activated carbon exhibited excellent microporous and mesoporous structure with a specific surface area that ranges between 30 and 254 m2·g−1 as measured by BET analysis. The morphology and structure of the produced materials are analyzed through Field Emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Boehm titration, X-ray Photoelectron Spectroscopy (XPS) and Raman Spectroscopy. X-ray photoelectron spectroscopy indicates that a considerable amount of oxygen is present in the materials. The functional groups in the activated carbon enhanced the electrochemical performance and improved the material’s double-layer capacitance. The carbonized composite activated at 700 °C exhibited excellent capacitance of 456 F g−1 at a specific current of 0.25 A g−1 in 6 M KOH electrolyte and showed excellent stability after 10,000 cycles. Besides being a low cost, the produced materials offer good stability and electrochemical properties, making them suitable for supercapacitor applications.

“…Recently, biomass-based carbon nanofibers, carbon spheres, and carbon membranes have shown promising electrochemical performance in supercapacitors. [7][8][9] However, biocarbon electrodes conventionally exist in powder form owing to their characteristics and preparation processes, which may restrict their application prospects. Therefore, preparation of carbon electrodes with a stable selfsupporting monolith structure and hierarchically porous structures from natural biomass by a facile method has attracted increasing attention.…”
