Description
Technical field
The present invention relates to capacitor diaphragm technical field, particularly relate to a kind of non-weaving cloth tear-proof antibacterial capacitor composite diaphragm material.
Background technology
Ultracapacitor is the accumulator of a kind of great market competitiveness, owing to it can realize quick charge, heavy-current discharge, and has the charge lifetimes of more than 100,000 times, needs to occupy critical role in the application of high-multiplying power discharge in short-term at some.The extensive of this Novel energy storage apparatus of ultracapacitor is paid attention in also result in worldwide by hybrid vehicle and the requirement to electrical source of power for the electric automobile.In the composition of ultracapacitor, electrode, electrolyte and the diaphragm paper performance on ultracapacitor plays conclusive impact.The electrode of current ultracapacitor and electrolyte are the focuses of research, but people are not high for research and the attention rate of barrier film.
The diaphragm paper of ultracapacitor is positioned between two porous carbon electrodes, and complete wetting is in the electrolytic solution together with electrode, plays the effect of isolation during repeated charge, stops electronics conduction, prevents from contacting the internal short-circuit causing between the two poles of the earth.This requires the insulator that diaphragm material is electronics, has good isolation performance, and its hole should be as far as possible less than the minimum grain size of electrode active surface material.The necessary aperture of the preferable diaphragm paper of isolation performance is little, the circulation of electrolyte so can be made to decline, battery charging and discharging hydraulic performance decline；And electrolyte to be impregnated with rate higher, ion is more more by the good diaphragm material often hole of property, easily causes and contacts the internal short-circuit causing between the two poles of the earth.The maximum advantage of ultracapacitor be charge/discharge rates fast, can be with high power discharge, therefore, diaphragm material will thinner towards thickness, porosity is higher, aperture is less and the contour performance trend development that is more evenly distributed.
The material being currently used for diaphragm of supercapacitor mainly has cellulosic separator paper and conventional batteries barrier film, and High-performance diaphragm paper manufactures technical difficulty, and price is high；Conventional batteries membrane thicknesses is thicker, and porosity is low, and to electrolyte compatibility difference, and electrostatic spinning nano fiber film manufacturing technology is simple, low cost, and barrier film porosity is up to 90%, good to electrolyte compatibility, but a disadvantage is that intensity is not high.If cellulosic separator paper can be combined with electrospun fibers film, learning from other's strong points to offset one's weaknesses, low cost, the composite diaphragm material that porosity is high, intensity is big can be obtained.
