NOVELTY - Preparing graphene and polyaniline composite fiber electrode material involves washing the polyaniline with deionized water and dry it to obtain first product, adding first product to an organic solvent, ultrasonically dispersing, and magnetically stirring to obtain second product, adding graphene oxide to second product, dispersing it ultrasonically at (-)3-5 degrees C, then adding deionized water dropwise under magnetic stirring to obtain graphene oxide and polyaniline composite gel to namely third product. The third prepared product is put into fibrous electrode material, namely fourth product, which undergo chemical reduction or thermal reduction, and vacuum drying to obtain electrode material. USE - Method for preparing graphene and polyaniline composite fiber electrode material. ADVANTAGE - The method enables to prepare graphene and polyaniline composite fiber electrode material is easy to agglomerate and graphene sheets are easy to densely stack during the compounding process of polyaniline and graphene. The electrochemical performance of the electrode material is greatly improved, and the method has the beneficial effects of simple operation, cost-effective, and easy large-scale preparation.
