Description
Technical field
The present invention relates to battery preparation technology field, specifically a kind of compound AGM partition boards of high-performance.
Background technology
There are mainly two types of current valve controlled sealed lead-acid accumulator partition board technologies, the first is to add colloid using PE partition boards
Technology, second is AGM partition boards.The country is mainly produced in such a way that AGM partition boards are closely assembled at present, using what is be closely assembled
Purpose is in order to inhibit the active material softening and shedding of positive plate, to promote battery life, after being closely assembled of battery can influence
The larger colloidal electrolyte of the filling of continuous electrolyte, especially viscosity.Most of producers, which use, at present is not added with glue or adds relatively low
The mode of the electrolyte of colloid concentration solves the problems, such as that filling is difficult, and electrolyte point easily occurs in the battery produced using this kind of mode
Layer, cell sealing reaction efficiency is low, influences the service life of battery.
Invention content
To solve the above problems, the present invention provides a kind of compound AGM partition boards of high-performance, there is intensity height, the wet rebound of partition board
Performance is good, can effectively inhibit the layering of electrolyte using battery made of the partition board, battery oxygen combined efficiency is high, cycle life
It is long.
The technical solution adopted by the present invention is：A kind of compound AGM partition boards of high-performance, by the raw material group of following mass percent
At：The aerosil of 5-15%, the sodium carboxymethylcellulose of 0.1-0.5%, the polypropylene fibre of 0.5-2%, 35-45%'s is straight
The high alkali glass fibre cotton that diameter is 0.3-0.6 μm, remaining is the high alkali glass fibre cotton of 1-4 μm of diameter, wherein the gas phase two
The specific surface area of silica is 190-210m2/ g, a diameter of 3-8 μm of the polypropylene fibre.
Preferably, the compound AGM partition boards of high-performance, are made of the raw material of following mass percent：8% aerosil,
0.4% sodium carboxymethylcellulose, 1.2% polypropylene fibre, 38% a diameter of 0.3-0.6 μm of high alkali glass fibre cotton,
The remaining high alkali glass fibre cotton for 1-4 μm of diameter, wherein the specific surface area of the aerosil is 190-210m2/ g, institute
State polypropylene fibre a diameter of 3-8 μm.
In AGM partition boards of the present invention, 1, high alkali glass fibre cotton be main constituents, it is different straight by adding different proportion
The porosity of the high alkali glass fibre cotton control separator paper of diameter, inhales the parameters such as sour rate, quantitative at maximum diameter of hole.
2, aerosil is the chief component of colloid, is filled it into AGM partition boards, and battery adds electrolyte
Afterwards, Ludox is formed under acidic environment, it is in gel state to make electrolyte, inhibits the layering of sulfuric acid in electrolyte, passes through simultaneously
Control electrolysis saturation degree, makes gel-forming crack, and it is multiple that the oxygen arrival cathode that anode generates when being conducive to battery charging carries out oxygen
It closes, reduces the percentage of water loss of battery, promote the service life of battery.
3, the effect of sodium carboxymethylcellulose is：Aerosil particle is smaller and inviscid, is encapsulated in battery production
It easily falls off from separator paper in the process, addition sodium carboxymethylcellulose can effectively avoid this by silica-bonded together
The appearance of kind problem, the sodium carboxymethylcellulose that battery fills in electrolyte rear bulkhead can dissolve in the electrolytic solution, battery
At in the process water and carbon dioxide can be produced by the brown lead oxide oxidation of anode, battery performance is not interfered with.In addition, if addition
A high proportion of aerosil can influence the intensity of separator paper, influence the encapsulating of battery, by add proper proportion poly- third
Alkene fiber can effectively improve the intensity and resilience of separator paper, eliminate this kind influence.
The beneficial effects of the invention are as follows：1, aerosil can inhibit the layering of sulfuric acid in electrolyte, be conducive to battery
The oxygen arrival cathode progress oxygen that anode generates when charging is compound, reduces the percentage of water loss of battery, promotes the service life of battery.2、
Sodium carboxymethylcellulose by silica-bonded together, prevent in battery production encapsulation process aerosil particle from every
It falls off in paperboard, can also effectively improve the intensity and resilience of separator paper, a high proportion of aerosil is avoided to influence partition board
The intensity of paper influences the encapsulating of battery.3, the compound AGM partition boards have intensity height, partition board Wet-resilient can be good, are fabricated to battery
Effectively inhibit the layering of electrolyte, battery oxygen combined efficiency is high, has extended cycle life.
