  • effect of carbon coating on electrochemical performance of treated natural graphite as lithium ion battery Anode Material
    Journal of The Electrochemical Society, 2000
    Co-Authors: Masaki Yoshio, Kenji Fukuda, Hongyu Wang, Yoichiro Hara, Yoshio Adachi
    Abstract:

    Carbon-coated natural graphite has been prepared by thermal vapor decomposition treatment of natural graphite at 1,000 C. Natural graphite coated with carbon showed much better electrochemical performance as an Anode Material in both propylene carbonate-based and ethylene carbonate-based electrolytes than bare natural graphite. The effect of carbon coating on the electrochemical performance was investigated by solid-state {sup 7}Li-NMR in conjunction with standard electrochemical techniques.

  • nanocrystalline cop thin film as a new Anode Material for lithium ion battery
    ChemInform, 2013
    Co-Authors: Yanhua Cui, Mingzhe Xue, Xiaoling Wang, Xiaojiang Liu

  • nanocrystalline cop thin film as a new Anode Material for lithium ion battery
    Journal of Alloys and Compounds, 2013
    Co-Authors: Yanhua Cui, Mingzhe Xue, Xiaoling Wang, Xiaojiang Liu
    Abstract:

    Abstract Nanocrystalline CoP thin film was prepared by pulsed laser deposition (PLD) and the electrochemical investigation of CoP as Anode Material for lithium ion battery was reported for the first time. The reversible discharge capacity of CoP/Li cell cycled between 0.1–3.0 V was found in the range of 788.0–1055.7 mAh g−1 during the first 25 cycles. A reversible couple of redox peaks at 0.63 and 1.02 V was observed in the first cycle of cyclic voltammetry (CV) curves. Ex situ transmission electron microscopy (TEM) and selected-area electron diffraction (SAED) revealed the fully decomposition of CoP to Co/Li3P composite after discharging the CoP/Li cell to 0.1 V and the re-formation of CoP nanocrystalline structure after re-charging to 3.0 V, demonstrating a fully reversible conversion reaction mechanism between CoP and Co/Li3P composite. High utility of trivalent phosphorus benefits the reversibility and capacity of CoP and makes it potential Anode Material for future lithium ion battery.

  • free standing electrospun carbon nanofibres a high performance Anode Material for lithium ion batteries
    Journal of Physics D, 2012
    Co-Authors: Suresh P Kumar, Rahul Sahay, Vanchiappan Aravindan, Jayaraman Sundaramurthy, Wong Chui Ling, Velmurugan Thavasi, S G Mhaisalkar, Srinivasan Madhavi, Seeram Ramakrishna
    Abstract:

    Free-standing carbon nanofibres (CNFs) are prepared by the carbonization of poly-acrylonitrile using a simple electro-spinning technique. The electro-spun fibres are studied as an Anode Material for lithium-ion batteries in half-cell configurations. The fibres showed an initial discharge capacity of 826 mAh g −1 at a current density of 200 mA g −1 and exhibited an appreciable capacity profile during cycling. The Li-storage mechanism has been explained based on the cyclic voltametric and galvanostatic cycling results. (Some figures may appear in colour only in the online journal)

  • Investigation of FeB alloy prepared by an electric arc method and used as the Anode Material for alkaline secondary batteries
    Electrochemistry Communications, 2009
    Co-Authors: Ying Bai, Li-xin Yang
    Abstract:

    Abstract High active FeB alloy was prepared by an electric arc method, and used as the Anode Material for alkaline secondary batteries. The structural characteristics of the as-prepared FeB alloy were studied using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), and the electrochemical performances were investigated using cyclic voltammetry (CV) and charge–discharge test. The FeB alloy achieves an excellent reversible capacity of 312 mA h/g as well as a good cycleability, and is proved to be a promising low-cost and high performance Anode Material for alkaline secondary batteries.

  • nano sn hard carbon composite Anode Material with high initial coulombic efficiency
    Journal of Power Sources, 2008
    Co-Authors: Bingkun Guo, Ying Bai, Jie Shu, Kun Tang, Zhaoxiang Wang, Liquan Chen
    Abstract:

    Nanoscaled tin (Sn) particles were embedded in the mesopores of hard carbon spherules (HCS) to form a composite Anode Material for lithium ion batteries. The structure of the obtained composite was characterized by X-ray diffraction (XRD) and the electrochemical performances were evaluated by galvanostatic cycling and cyclic voltammetry. It is found that embedding Sn nanoparticles into HCS not only results in a composite Material with high-lithium storage capacity and capacity retention, but also increases the initial coulombic efficiency of the composite. Based on the infrared spectroscopic analysis, the enhanced initial coulombic efficiency is attributed to the nano-tin-induced decomposition of the ROCO2Li. species in the solid electrolyte interphase (SEI) layer.
