Abstract

The invention relates to an electrically conductive organic polymer coated phenolic resin-based porous carbon composite material. A preparation method for the material comprises the following steps: (1) water-soluble phenolic resin and curing agent are orderly added in an anhydrous alcohol solution to obtain a mixture; after stirring and curing operation, a cured phenolic resin is obtained; (2) phenolic resin microspheres obtained in step (1) are carbonized and calcined in an inert gas atmosphere at a temperature of 850 to 950 DEG C to obtain phenolic resin-based porous carbon; (3) the phenolic resin-based porous carbon obtained in step (2) is added to a 30-60 ml acetone solution, and then a surfactant is added to obtain a mixed solution after ultrasonic dispersion. Electrically conductivepolymer monomers are ultrasonically dispersed in an acetone solution to obtain an electrically conductive polymer monomer acetone solution. The electrically conductive polymer monomer acetone solution is added dropwise to the mixed solution, microwave hydrothermal reaction was performed, and the electrically conductive organic polymer coated phenolic resin-based porous carbon composite material with high specific capacity, specific energy density, and good cycle stability is obtained.

Description

technical field [0001] The invention relates to the technical field of new energy materials, in particular to a conductive organic polymer-wrapped phenolic resin-based porous carbon composite material. Background technique [0002] With the increasing severity of the global energy crisis, the preparation of new energy storage devices is an urgent issue, and supercapacitors are a typical energy storage device, and their excellent electrochemical performance will become an important part of future social energy storage devices. Composition one. [0003] Phenolic resin-based porous carbon composites have been widely used as electrode materials for supercapacitors due to their high specific surface area, excellent electrical conductivity, and chemical stability. However, during the charging and discharging process, the phenolic resin-based porous carbon The micropores limit the insertion and extraction of electrolyte ions, and it is impossible to obtain a satisfactory capacitan...
