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.

“…3 shows the first and second charge/discharge profiles of the samples at a current density of 0.05 A g À1 . All of the samples show a plateau between 0.9 and 0.5 V and a large irreversible capacity in the first discharge/charge cycle, which are common phenomena for carbon materials, especially for hard carbon [4,19,21,[35][36][37]. The large irreversible capacity is originated from the formation of the SEI layer [4,21,35,37].…”

“…The specic capacity for NiO powder reaches 1370 mA h g À1 in the initial cycle eventually leveling off to 350 mA h g À1 in the 50 th cycle due to fatal volume changes, which is near the value of the pure CNF. [37][38][39] Fig . A capacity retention of more than 900 mA h g À1 is recorded aer the second cycle without an obvious capacity fading except for an initial capacity of 1400 mA h g À1 .…”

Hierarchically coaxial carbon nanofiber/NiO (CNF/NiO) core-shell nanocables for lithium ion batteries are prepared to coat a-Ni(OH) 2 on the surface of electrospun carbon nanofibers (CNF) by electrophoretic deposition, followed by thermal processing in air. In the coaxial CNF/NiO nanocables, a NiO shell of about 20 nm thick is formed by coating with nano-furs outward on the surface of a CNF core of 200 nm in diameter, which is the main factor for providing a three-dimensional (3D) structure. The NiO shells, comprising of abundant inner spaces on the surface of CNF and high conductivity of 1D CNF, are deeply dependent on the enhancement of electrochemical rate capability. Abundant inner spaces in the NiO shell and the interconnected network between nanocables facilitate the mass transfer. The CNF core with the cushioning effect created through the elastic deformation provides electrochemical stability by protecting both radial compression and volume expansion originating from NiO shells radially.The CNF/NiO nanocables deliver a high reversible capacity of 825 mA h g À1 at 200 mA g À1 after 50 charge-discharge cycles without showing obvious decay. The coaxial CNF/NiO nanocables increase not only electrochemical capability but also electrochemical stability.
