Abstract
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 .mu.m and has a press molding density of 1 to 1.6 g/cm.sup.3.
