“…W. Li et al [91] synthesized a spherical hard carbon (SHC) by one-step programmed heating of potato starch under an inert atmosphere, showing a reversible capacity of about 531 mAhg À 1 with a first-cycle coulombic efficiency of 73.1 % and also displays good rate capability (at 5 C rate, it retains a capacity of 87 % to that at 0.1 C). Similarly, different types of HCs are synthesized from different sources, including resin, [92][93][94] pitch, [95,96] and various biomass such as lignin, [97,98] starch, [99,100] cellulose, [101] etc. L. Xie et al provide a detailed review of the Liion storage in different HCs synthesized at different conditions from various raw materials.…”

Carbon‐based materials have played a pivotal role in enhancing the electrochemical performance of Li‐ion batteries (LIBs). This review summarizes the significant developments in the application of carbon‐based materials for enhancing LIBs. It highlights the latest innovations in different types of carbon materials such as graphite, soft carbon, hard carbon, and various carbon nanostructures, including design and synthesis. Additionally, the feasibility of developing flexible self‐supported electrodes for wearable devices is underlined. More emphasis is given to elucidating the Li‐ion storage mechanisms inherent in various carbon materials, illustrating the variations in Li‐storage that arise as the structure transitions from order to disorder and from bulk to the nano realm. Furthermore, the use of carbon composites, which incorporate different alloy/conversion/intercalation type materials with carbon matrices, is discussed in view of their improved electrochemical performances in terms of energy density, power density, and cycling stability. The review underscores the growing importance of carbon materials in addressing the ever‐increasing demand for high‐performance energy storage solutions and also addresses the remaining challenges and future perspectives, aiming to provide future research directions.

“…63 However, the higher SSA does not necessarily equate to a low ICE. 59,[64][65][66] To achieve a comprehensive investigation of porestructure, researchers need to employ not only N 2 adsorptiondesorption but also, He and CO 2 adsorption-desorption testing to explore ultra-micropores. In addition, small-angle X-ray scattering (SAXS) is a vital technique for studying closed pores in detail.…”

“…The Zn-CTW showed a single broad peak at around 2θ=8.08, pointing out the semi-crystalline structure of the carbonized sample. Shifting a peak position to a low angle indicates disordered cages and microporosity, whereas an increase in peak strength means an increase in interplanar crystal spacing, which contributes to adsorption (30). Only the small peak at around 2θ=30 may be attributed to the ZnO crystal formed because of using a chemical modification (31).…”

Preparation of adsorbent materials in powder and polymeric composite form was achieved by controlled carbonization of ZnCl2 pretreated textile waste at low temperatures. Structural and surface properties of carbonized textile waste samples (CTW) and polymeric composites were prepared by the addition of CTW to PVDF-DMF solution at 0, 5, 10, 15, 20, and 30 mass% ratios analyzed by FT-IR, XRD, SEM, and BET analysis. Adsorption performances of powder and composite adsorbents were investigated for MO dye removal from an aqueous solution. Zn-CTW obtained with carbonization of ZnCl2 treated textile waste at 350 °C presented 117.5 mg/g MO removal. Those were higher than CTW-350 and CTW-400. The presence of 1545 cm-1 band at the IR spectrum of Zn-CTW proved the formation of functional groups that increase dye adsorption performance with honeycomb-like pores on the surface. Zn-CTW reflected its properties onto the PVDF matrix. Improved porosity percentage, BET surface, and dye adsorption of Pz20 were recorded as 105.3, 15.22 m2/g, and 41 mg/g, respectively, compared with bare PVDF. Disposal of textile waste and preparation of functional activated carbon were achieved in a low-cost and easy way. Zn-CTW loaded PVDF composites are promising materials to use as a dye removal adsorbent from water or filtration membranes.
