摘要：NOVELTY - Preparation of conductive polypyrrole/lignin sulfonate complex comprises polymerizing lignin sulfonate and pyrrole monomer at - 5-5 degrees C for 10-24 hours in the presence of oxidizing agent, stopping reaction, filtering to obtain filter cake, washing with ethanol, and drying to 50-80 degrees C for 20-30 hours. USE - Method for preparation of conductive polypyrrole/lignin sulfonate complex used for energy storage material (claimed). ADVANTAGE - The complex has specific surface area of 25-65 m2/g, charge density of 0.2-10 A/g, capacity retention ratio of more than 70%, excellent rate characteristics.
