Description
Technical field
The present invention relates to electrode material preparation field, more particularly to a kind of carbon cloth table for flexible super capacitor electrode
Surface modification method.
Background technology
As petroleum resources are increasingly short, and pollution of the internal combustion engine tail gas discharge of burning petroleum to environment is more and more tighter
For weight (especially in big or middle city), people are studying various energy storages and reforming unit.Lithium ion battery, traditional capacitance
Device and ultracapacitor are fast-developing as new energy storage device, wherein since ultracapacitor has than lithium ion battery
The power density and cyclical stability of higher, and be widely studied with the energy density than traditional capacitor bigger.However, by
It is that the quick adsorption based on ion is desorbed in its energy storage mechnism, therefore limits its energy density.
Super capacitor is also known as electrochemical capacitor, it is far above as a kind of new energy storage device, charge storage
Conventional physical capacitor, and charging rate, efficiency and security are due to storage battery；With doing energy much than traditional capacitor
Metric density and the power density more much bigger than lithium battery, the advantages that integrating high-energy-density, high security, long-life.This
Prominent characteristic causes ultracapacitor to be considered as this century most promising new green power a bit.The U.S.《Explore》Magazine
In January, 2007, one of seven big scientific discovery of the world in 2006 is classified as by ultracapacitor, it is believed that " ultracapacitor is energy storage
A revolutionary development in field is deposited, and traditional storage battery will be substituted in some fields ".
Using carbon cloth activation prepare the columnar ultracapacitor of porous carbon materials merely, with the discharge and recharge time it is short (1~
30s), the advantages that good cycle (10~500,000 times), coulombic efficiency high (99%).However, due to carbon material feature itself
Limitation, if specific capacitance is not as specific surface area is linearly increasing, flourishing micropore canals cannot all by electrolyte ion profit
With etc., carbon cloth has breakthrough raising as carbon material still hardly possible in specific capacitance.In addition, being compared with secondary cell, prepared by carbon cloth
Porous carbon supercapacitor unit mass/volume capacity it is still too small, be with carbon material assembling ultracapacitor energy
Metric density is restricted.Therefore, on the premise of electrochemical power density height is kept, how to further improve its energy density into
For the key of flexible super capacitor research.
In order to improve the energy density of whole device, fake capacitance material is as ultracapacitor container electrode material in recent years
Research hotspot.Traditional method, by fake capacitance material direct growth carbon cloth, forms needle-shaped or sheet array, Neng Gouti
The capacitance of high ultracapacitor, has certain advantage.But since the needle-shaped or sheet-like morphology of active material influences, group
The presence of the problems such as poly- so that cyclical stability is deteriorated, and selects the inert or small capacitive property for example porous gold of base material
Belong to substrate, carbon pipe, graphene, burlap or the small business carbon cloth of specific surface area greatly limit the performance of electrode material again.Cause
This, there is an urgent need for research and develop a kind of carbon cloth surfaces method of modifying for flexible super capacitor electrode.
