“…It exhibits superior Li storage properties. CNFs are another typical 1D carbon nanomaterials, which have the characteristics of large-scale production, adjustable porosity, large specific surface area and advantageous conductivity [84,97]. A kind of self-supporting organic cathode showing controlled redox kinetics was studied by in-situ polymerization of PI film inside porous CNF conductive framework [98].…”

Recent progress and challenges of carbon materials for Zn‐ion hybrid supercapacitors

Zinc-ion hybrid supercapacitors (ZHSCs) have garnered increasing attention as promising energy storage devices in recent years, as they combine the advantages of high-energy Zn-ion batteries and high-power supercapacitors. However, the development of ZHSCs is still in its infancy and there are many bottlenecks to overcome. In particular, the challenge induced by the limited ion adsorption capability of carbon-positive electrodes severely restricts the energy density of ZHSCs. Therefore, it has become a key issue to design novel carbon-positive electrodes that enable high energy density yet do not deteriorate the intrinsic power capability and long-term durability. This study focuses on recent achievements in synthesis, morphology, and electrochemical performance of various carbon materials applied in ZHSCs. The modification strategies to optimize their electrochemical performance are briefly summarized. In addition, current challenges and future opportunities in this field are also outlined. This review will be beneficial to provide an organized framework for the research systems of carbon-positive electrodes and develop novel ZHSCs with high energy density.

“…Carbon-based supercapacitors have been considered as preferable alternative devices to replace traditional energy storage systems on account of their multiple advantages, including low weight and cost, high power delivery, and long cycling stability [ 4 , 5 , 6 ]. Heteroatom-doped carbon materials also have been an efficient method to enhance the pseudocapacitance effects, and the fabrication process is relatively easy to handle, versatile, and general [ 7 ].…”

Heteroatom doping is an effective way to raise the electrochemical properties of carbon materials. In this paper, a novel electrode material including nitrogen, phosphorus, and sulfur co-doped pyrolyzed bacterial cellulose (N/P/S-PBC) nanofibers was produced. The morphologies, structure characteristics and electrochemical performances of the materials were investigated by Scanning electron microscopy, Fourier transform infrared spectra, X-ray diffraction patterns, X-ray photoelectronic spectroscopy, N2 sorption analysis and electrochemical measurements. When 3.9 atom% of nitrogen, 1.22 atom% of phosphorus and 0.6 atom% of sulfur co-doped into PBC, the specific capacitance of N/P/S-PBC at 1.0 A/g was 255 F/g and the N/P/S-PBC supercapacitors’ energy density at 1 A/g was 8.48 Wh/kg with a power density of 489.45 W/kg, which were better than those of the N/P-PBC and N/S-PBC supercapacitors. This material may be a very good candidate as the promising electrode materials for high-performance supercapacitors.
