摘要

选用国产山东天然石墨 ,比较系统地研究了其材料的结构、物理和电化学性能 .X射线衍射分析结果表明 ,国产天然鳞片微粉石墨由六方结构 (2H)和菱方结构 (3R) (含 30 %的菱方结构 )组成 ,是结晶完整性好的石墨 .作为锂离子电池负极材料 ,天然石墨具有高电压、高容量的特点 .但因自身结构的局限性 ,不能与含碳酸丙烯酯 (PC)的电解质相匹配

Abstract

The structure, physical characteristics and electrochemical properties of the natural graphite produced in Shandong province have been studied. The result of X-ray diffraction showed that the graphite consisted of hexagonal structure and rhombic structure (30% rhombic structure). It was fine crystal graphite. Used as a negative material of Lithium ion battery, the natural graphite showed excellent voltage and high energy capacity, but poor compatibility with electrolyte solution containing propylene carbonate (PC) for its own structure limitation.
