一种锂离子电池正极材料复合导电剂
摘要：
本发明公开了一种锂离子电池正极材料复合导电剂。本发明的锂离子电池正极材料复合导电剂，除常规的导电材料外，还包含有多孔活性炭，所述的多孔活性炭富含中孔，孔径分布范围为2～50nm，比表面积为500～4000m2/g。和单纯的乙炔黑导电剂相比，使用复合导电剂的锂离子电池正极材料具有高的比容量和良好的循环稳定性。
摘要（英）：

The invention discloses a composite conductive agent for an anode material of a lithium ion battery. Except common electric conducting material, the composite conductive agent also comprises porous active carbon, wherein the porous active carbon is rich in mesopores of which the pore size distribution range is between 2 and 50nm and the specific surface area is between 500 and 4,000m< 2 >/g. Compared with a single acetylene black conductive agent, the anode material of the lithium ion battery adopting the composite conductive agent has high specific capacity and excellent cycle stability.
