“…lithium ions, thus improving the reversible capacity, while on the other hand the growth of graphitic carbon leads to the capacity deterioration because graphitic carbon has lower capacity than amorphous carbon. BDC-900 compromises the porous properties and graphitic carbon, therefore it exhibits the highest charge capacity [42].…”

The KOH-activated sample demonstrated enhanced electrochemical performance due to its high surface area and abundant mesoporous structure. Bean-dreg-derived carbon materials used as superior anode material for lithium-ion batteries AbstractThe structures of modified carbons from bean dregs were regulated via graphitization treatment and chemical activation. The microstructure and electrochemical performance were studied using X-ray diffraction, Raman spectrometer, SEM and TEM techniques. The electrochemical performance was investigated using electrochemical methods. After heat-treatment at 2800 O C, the obtained BDC-2800 possessed a high degree of graphitization and showed an outstanding cycling performance, delivering capacity decay from 423 to 396 mAh g -1 at 0.1 C after 100 cycles. The chemical-treated carbons also demonstrated enhanced electrochemical performance, especially for the KOH-treated sample. The BDC-K displayed superior specific charge capacity of 801 mAh g -1 at 0.1 C, and showed an impressive rate capability of 643 mAh g -1 at 1 C. In addition, this sample delivered capacity retention of 94%after 500 cycles at 1 C. This good electrochemical performance was mainly due to its high surface area and abundant mesoporous structure.

Summary Sulfur doping has been regarded an energetic route to optimize the lithium storage properties of carbon‐based electrode materials. In this work, sulfur‐doped shaddock peel–derived hard carbon is successfully prepared by a KOH‐ and C2H5NS‐assisted pyrolysis procedure. It is demonstrated that sulfur doping has strong effect on surface activation and graphitization enhancement, which results in the significant enhancement of the surface adsorption capacity and reaction kinetics of the hard carbon materials. When employed as a lithium ion batteries (LIBs) anode, the as‐obtained hard carbon demonstrates excellent cycling and rate properties, presenting a great specific capacity of 738 mAhg−1 at 50 mAg−1 after 200 cycles, as well as 491 mAhg−1 at 200 mAg−1 after 300 cycles. Even at 1000 and 2000 mAg−1, the hard carbon provides a large rate capacity of 283 and 179 mAhg−1, respectively. Besides, it is revealed that the Li+ storage process is determined by the surface‐induced pseudocapacitive process, whose capacitive proportion reach 60% at 0.5 mVs−1. This work suggests that the low cost and eco‐friendly sulfur‐doped shaddock peel–derived hard carbon is a very prospective LIB anode material.

Different formational process could lead to diverse morphologies and properties. Therefore, the study on formation mechanism was very important to figure out the influence of formational process. The corn stalk core (CSC), as a kind of renewable biological resource, could be used as raw materials to prepare activated carbon materials (ACs) via carbonizing and activating. The transformational mechanisms on the every step and the variation of various components in the CSC were studied, which was supposed the feasible methods to enhance the performance. In addition, the process of cellulose trans-forming into the carbon and the carbon structure were deduced. The carbon materials prepared were characterized through a series of equipments, such as scanning electron microscopy (SEM) and nitrogen adsorption-desorption measurements (BET), the obtained results showed that the ACs with more pores and higher specific surface area than the materials unactivated. In the end, the ACs was applied as anode in the lithium ion batteries (LIBs) to test their electrochemical performances. Comparing the carbon materials unactivated, the role of activated process was revealed.
