“…They used poultry featherber and polyvinylpyrrolidone (PVP) as the main source of carbon, and investigated the effect of temperature. 20,21 Activated carbon, as an adsorbent with a high absorption capacity and low cost, has found many applications in adsorption from liquid phase and/or gas phases. One of the applications of this substance in adsorption from a liquid phase is decolorization of sugar solution, drinking water treatment, wastewater treatment, gas absorption in gas masks, and solvent recovery systems.…”

Li4Mn5O12 with nanotubes morphology was successfully prepared by hydrothermal and solid phase reaction. The as‐obtained adsorbent was determined by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and N2 ad/desorption technologies. The characterization results indicated that spinel H4Mn5O12 took on two‐dimensional nanotubes morphology with the diameter of pore ∼200 nm, BET surface area is 92.997 m2⋅g−1, and the corresponding pore size centers at 3.4, 35.9 and 156.5 nm. The adsorption experimental results showed that the maximum Li+ adsorption capacity of H4Mn5O12 was as high as 37.0 mg⋅g−1, and the adsorption process fit well with Langmuir model. In addition, adsorption kinetic experimental data were well fitted by the pseudo‐second‐order model, which indicated the adsorption process followed chemisorption involving in ion exchange. The effects of co‐existing cations on lithium recovery suggested that Na+, K+, Ca2+ and Mg2+ ions had very small effect on recovery of lithium. The regeneration of H4Mn5O12 for the multicyclic Li+ adsorption and desorption were also assessed. The result implied that most of Li+ could be desorbed within 40 min, but the adsorption capacity decreased when the number of cycles was five, which indicated that the structure of H4Mn5O12 was needed to be improved. Lithium adsorption onto H4Mn5O12 could be attributed to electrostatic interaction and ion exchange between Li+ and H+ according to the results of adsorption isotherm and kinetics properties.

Summary In the last decades, fuel scarcity and increasing pollution level pave the way for an extensive interest in alternatives to petroleum‐based fuels such as biodiesel, solar cells, lithium ion batteries, and supercapacitors. Among them, structural supercapacitors have been considered as promising candidates for automotive industries in present time. Herein, the use of carbon fiber‐based supercapacitors in automotive applications is reviewed. Carbon fiber is an excellent candidate for vehicle body applications, and its composites could be widely used in the development of supercapacitors that could provide both structural and energy storage functions. Different surface modification processes of the carbon fiber electrode to enhance the electrochemical as well as mechanical performances are discussed. The advantages of the glass fiber separator and its comparison with other types of dielectric media have been incorporated. The synthesis procedures of the multifunctional solid polymer electrolyte and its significance have been also elaborated. The fabrication process, component selection, limitations, and future challenges of these supercapacitors are briefly assimilated in this review. Copyright © 2017 John Wiley & Sons, Ltd.
