“…Recently, many attentions have been attracted on next-generation high-capacity anode materials such as Si [10], Sn [11], and their oxides, and transition metal oxides (CuO, MnO 2 , Fe 2 O 3 , Co 3 O 4 ) [12][13][14][15][16][17][18]. However, such materials usually exhibit evident volumetric changes during charge/discharge processes, with a large irreversible capacity loss compared to carbonaceous materials [19,20].…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. 3. 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.

High lithium anodic performance of highly nitrogen-doped porous carbon prepared from a metal-organic framework

2014

View full text Add to dashboard Cite

Theoretical and experimental results have revealed that the lithium-ion storage capacity for nitrogen-doped graphene largely depends on the nitrogen-doping level. However, most nitrogen-doped carbon materials used for lithium-ion batteries are reported to have a nitrogen content of approximately 10 wt% because a higher number of nitrogen atoms in the two-dimensional honeycomb lattice can result in structural instability. Here we report nitrogen-doped graphene particle analogues with a nitrogen content of up to 17.72 wt% that are prepared by the pyrolysis of a nitrogen-containing zeolitic imidazolate framework at 800°C under a nitrogen atmosphere. As an anode material for lithium-ion batteries, these particles retain a capacity of 2,132 mA h g À 1 after 50 cycles at a current density of 100 mA g À 1 , and 785 mAh g À 1 after 1,000 cycles at 5 A g À 1 . The remarkable performance results from the graphene analogous particles doped with nitrogen within the hexagonal lattice and edges.

“…The pink Mn‐MOF was obtained after drying at 60 °C for 4 h (detailed information can be seen in Figure S1, and Tables S1 and S2 in the Supporting Information). In the calcination process, there is a large temperature gradient, which leads to the transformation of microscale bulk single crystal Mn‐MOF (Figure S1d, Supporting Information) to submicroscale polyhedron manganese oxides (Figures S1e and S2, Supporting Information) 34. The structure of the product was investigated by X‐ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM).…”

A mini‐hollow polyhedron Mn2O3 is used as the anode material for lithium‐ion batteries. Benefiting from the small interior cavity and intrinsic nanosize effect, a stable reconstructed hierarchical nanostructure is formed. It has excellent energy storage properties, exhibiting a capacity of 760 mAh g−1 at 2 A g−1 after 1000 cycles. This finding offers a new perspective for the design of electrodes with large energy storage.
