New electrically conductive material suitable particularly for a secondary battery and a process for preparing the electrically conductive material are provided. The process for the preparation of the electrically conductive material comprises the steps of reacting a compound having conjugated double bonds with an oxidizing agent wherein the oxidizing agent comprises a cupric compound and a nitrile compound. The electrically conductive material comprises grainy polypyrrole obtained by reacting a pyrrole compound with an oxidizing agent which is constituted by primary particles having an average particle size of 0.01 to 0.4 µm and has a press molding density of 1 to 1.6 g/cm³.
本发明提供了特别适用于二次电池的新型导电材料以及制备该导电材料的工艺。 制备该导电材料的工艺包括以下步骤:使具有共轭双键的化合物与氧化剂反应,其中氧化剂包括铜化合物和腈化合物。 该导电材料包括通过使吡咯化合物与氧化剂反应而获得的粒状聚吡咯,该聚吡咯由平均粒径为 0.01 至 0.4 微米的初级颗粒构成,其压制成型密度为 1 至 1.6 克/立方厘米。
