摘　　要：简要概述了聚丙烯腈的制备方法,详细综述了聚丙烯腈的热解特性及用于锂离子电池电极材料的研究,结合本实验室工作情况讨论了其用于锂离子电池电极材料时存在的优势与不足,并提出了改进结构、完善其电化学性能的建议。Polyacrylonitrile is a macromolecule which has good processability due to its capacity of dissolving in solvent and can turn into an electrically conductive macromolecule by means of the heat treatment, so it has been attracting people＇s attention in the field of functional materials. After briefly summary on preparation of PAN, this paper reviewed in detail its thermal decomposition characteristic and the studied on using its pyrolytic products as electrode materials for lithium ion batteries. Combining with our work, the advantages and disadvantages of the electrode material were discussed. The methods of improving the configuration of this electrode material and perfecting its electrochemical performance were put forward in the end.
