PURPOSE:To make environmental control in electrode production easy and to increase storage performance of an electrode by using a conductive material obtained by the reaction of a specified conjugated compound, a cupric compound, and an oxidizing agent of nitrile compound in an electrode. CONSTITUTION:A conjugated compound such as thiophane and pyrrole is used as starting material and reacted with cupric compound and the oxidizing agent of nitrile compound in liquid phase to obtain a black, conductive, powdery reaction product. The reaction product is washed with nitrile compound solvent, then thermoplastic resin is added to the purified product and press-molded to form a positive electrode 1. The positive electrode 1 is combined with a lithium negative electrode 2 and a polypropylene nonwoven fabric separator 3 to form a secondary battery. The obtained conductive product is easy to produce and has good oxidation resistance and large conductivity. By using this material, the environmental control for electrode production is easy and the storage performance of the electrode is also increased. |
