Abstract
The invention discloses a kind of aramid fiber electrodes and preparation method thereof.The preparation method of aramid fiber electrode is that Nano silver grain, carbon nanotube, polypyrrole are successively coated on to the surface of aramid fiber in a manner of being chemically bonded, prepare aramid fiber electrode, two beam aramid fiber electrodes and electrolyte can be wound, obtain aramid fiber electrochemical capacitor.Compared with the polymer fiber electrochemical capacitor of prior art preparation, the features such as aramid fiber electrochemical capacitor provided by the invention has both high specific capacitance, high-energy density, high-mechanical property, high stability, good flexible and wearable property；Preparation method technique is controllable, is suitble to large-scale application.
Description
Technical field
The present invention relates to fiber electrodes, electrochemical capacitor and preparation method thereof, and in particular to a kind of aramid fiber electrode
And preparation method thereof.
Background technique
Fast development with wearable smart machine and the urgent need to sustainable energy, high-energy density fiber
Electrochemical capacitor is small-sized with its, lightweight, flexibility, efficiently, the advantages that being easily integrated, show huge application prospect.Fiber
Electrochemical capacitor is constituted by fiber electrode with electrolyte with parallel, winding, coaxial structure, therefore its performance largely takes
Certainly in fiber electrode material.In order to make wearable fiber electrochemical capacitor move towards application from concept, it is badly in need of exploitation and has both well
The high-performance fiber electrode of flexible, wearable property and excellent chemical property.
So far, multiple fiber be used to prepare the electrode of fiber capacitor.Wherein, carbon fiber is frangible, cannot be frequent
It is bent and is not easy to weave；Metallic fiber（Such as stainless steel fibre, nickel fiber）Though having ductility, matter is hard, has plasticity；
Graphene fiber and carbon nano-tube fibre are not suitable for large-scale production due to higher cost.Polymer fiber is flexible due to having,
It is the ideal material for preparing wearable fiber electrode.
However, there are three bottlenecks for existing polymer fiber electrode and its capacitor.First, the conductivity of electrode is low,
Lead to low energy densities.Polymer fiber generally passes through coated with carbon material（Such as carbon nanotube, graphene）, conducting polymer
Object（Such as polyaniline, polypyrrole）Or transition metal oxide（Such as manganese dioxide, zinc oxide）Obtain capacitive property.Although packet
Covered capacitance material, but polymer fiber does not contribute capacitive property, thus the specific capacitance of polymer fiber electrode and its
The energy density of capacitor is generally relatively low.Second, it is bonded poor between inorganic coating and fibrous matrix, is repeatedly deforming
Or clad may fall off performance is caused to deteriorate after electrochemistry circulation, cause the wearable property of fiber capacitor poor.Third,
The mechanical performance of existing polymer fiber capacitor can't reach requirement.Currently, usually fine with polyester fiber, polyamide
The matrix as polymer fiber capacitor such as dimension, polyurethane fiber, cotton fiber, their tensile property is usually very low, mainly
Meet the application in daily life, and is not suitable for the field that ballistic resistant products etc. have high requirements to mechanical performance.
Therefore, preparation has both the polymer fiber capacitor of excellent chemical property and good flexible, wearable property
It is still a challenge.In polymer fiber, aramid fiber is due to outstanding mechanical performance, hot property and chemical resistance
Can, huge concern has just been received since birth.But, aramid fiber electricity identical as other polymers fiber capacitor
The problem of capacitive property of container and cementability between inorganic coating object, still has to be solved.Development has both excellent electricity
The aramid fiber capacitor of chemical property, mechanical performance and good flexible, wearable property has significant application value.
Summary of the invention
In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide having both, high specific capacitance, high-energy are close
