The average particle size of the polymer is 290 to 490 nm.Formula (1) in formula (1), R1Is a hydrogen atom or a methyl group, R2Is an alkyl group having 4 to 10 carbon atoms. Therefore, when the energy storage device is applied to the super capacitor, the energy storage efficiency of the capacitor can be effectively improved.
Description
Technical field
The present invention relates to a kind of electrode of super capacitor resin combination, electrode of super capacitor slurry, super electricity
Container electrode and ultracapacitor.More particularly to a kind of electrode of super capacitor resin combination, prepared by it is super
Electrode for capacitors slurry can produce the electrode of super capacitor that adherence is good between electrode layer and collector, super capacitor
Device electrode slurry, electrode of super capacitor and the ultracapacitor with the electrode of super capacitor.
Background technology
Ultracapacitor (supercapacitor, hereinafter referred to as SC), also known as double-layer capacitor (electrical
Double layer capacitor, hereinafter referred to as EDLC), there is higher energy density than general battery, and with can be fast
The advantages that fast charge and discharge are with high circulation service life, therefore it is widely used for energy storage field.
Ultracapacitor is the electrochemical appliance being stored in electric energy in a manner of electric double layer on electrode.Super capacitor energy
Formed electric double layer structure is all adsorbed in storage and release from electrostatic charge.Due in such electric double layer repeated structure charge and discharge
During, loss of the general battery for electrolyte and electrode in electrochemical reaction process is hardly generated, so
With excellent reversible capacity and high circulation service life.However, in the processing procedure of the electrode of ultracapacitor, by winding
Step, therefore the peeling of the electrode layer on collector is be easy to cause, and the energy storage efficiency of capacitor is bad.
Therefore, how to improve adherence between electrode layer and collector, actually this field technology personnel desire most ardently solution at present
The problem of.
