Abstract

The invention discloses an environment-friendly super capacitor electrode material simple to prepare. The super capacitor electrode material is characterized by being prepared from raw materials in parts by weight as follows: 0.3-0.5 parts of polyoxyethylene sorbitan monolaurate, 2-3 parts of carbon nanofiber, 1-2 parts of reinforced fiber, 1-2 parts of 3,4-ethylenedioxy thiophene, 1-2 parts of niobium carbide, 2-3 parts of tantalum carbide, 100-130 parts of modified waste-PVC (polyvinyl chloride)-based activated carbon, 1-2 parts of acrylic resin, 1-2 parts of phenyltriethoxysilane and 10-15 parts of distilled water. The porous electrode material with the high specific surface area and high electric conductivity is prepared from waste PVC and taken as a basal body; the doped tantalum carbide with excellent chemical stability, high-temperature performance and electric conductivity and the doped carbon nanofiber with the excellent surface effect enable other electrode materials to be well composited and have a synergistic effect. The super capacitor electrode material is non-toxic, environment-friendly, safe, efficient, simple in process and bright in application prospect.

Description

technical field [0001] The invention relates to the field of chemical energy materials, in particular to an environmentally friendly and easily manufactured electrode material for supercapacitors and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the rapid growth of the population, the resources and energy that human beings rely on are increasingly exhausted. The development of economical and efficient new energy is an important issue in today's world to solve these problems. Due to the advantages of high power density, short charging time and long service life, supercapacitors are widely used in electric vehicles, military, mobile communication equipment and other fields, which has attracted extensive attention of scientific researchers. Electrode materials are the core of the development of supercapacitor technology. Substances used as supercapacitor electrode materials should have appropriate thermodynamic stabili...
