Description
Technical field
The present invention relates to capacitor diaphragm technical field, particularly relate to the good aging resistance ultracapacitor of a kind of weatherability multiple
Close diaphragm material.
Background technology
Ultracapacitor is the accumulator of a kind of great market competitiveness, owing to it can realize quick charge, big electric current
Electric discharge, and there is the charge lifetimes of more than 100,000 times, in some need the application of high-multiplying power discharge in short-term, occupy critical role.
Hybrid vehicle and electric automobile also result in the requirement of electrical source of power in worldwide that this is new to ultracapacitor
The extensive attention of type energy storage device.In the composition of ultracapacitor, electrode, electrolyte and the diaphragm paper property to ultracapacitor
Conclusive impact can be played.Electrode and the electrolyte of ultracapacitor is the focus studied at present, but people are for barrier film
Research and attention rate the highest.
The diaphragm paper of ultracapacitor is between two porous carbon electrodes, and complete wetting is at electrolyte together with electrode
In, during repeated charge, play the effect of isolation, stop electronics conduction, prevent between the two poles of the earth, contacting the inside caused short
Road.This just requires that diaphragm material is the insulator of electronics, has good isolation performance, and its hole should be as far as possible less than electricity
The minimum grain size of pole surfactant.The necessary aperture of the preferable diaphragm paper of isolation performance is little, so can make the circulation of electrolyte
Property decline, battery charging and discharging hydraulic performance decline；And electrolyte to be impregnated with rate higher, ion is by the good diaphragm material often hole of property relatively
The most more, easily cause and between the two poles of the earth, contact the internal short-circuit caused.The advantage of ultracapacitor maximum is charge/discharge rates
Hurry up, can be with high power discharge, therefore, diaphragm material will thinner towards thickness, porosity is higher, aperture is less and is more evenly distributed
Contour performance trend development.
The material being currently used for diaphragm of supercapacitor mainly has cellulosic separator paper and conventional batteries barrier film, high-performance every
Film paper manufactures technical difficulty, and price is high；Conventional batteries membrane thicknesses is thicker, and porosity is low, poor to electrolyte affinity, and quiet
Electro spinning nanometer fiber membrane manufacturing technology is simple, low cost, and barrier film porosity is up to 90%, good to electrolyte affinity, but lacks
Point is that intensity is the highest.If cellulosic separator paper can be combined with electrospun fibers film, learning from other's strong points to offset one's weaknesses, can be become
The composite diaphragm material that this is low, porosity is high, intensity is big.
