In recent years, the research report is arranged, negative pole at battery adds additive, can reduce the internal resistance of cell, increasing particle conductive ability or prevention has the formation of the accessory substance of negative effect, but the adding of some additive, and one side has increased the cost of battery, on the other hand can be so that the continuous discharge performance of battery reduces or increases the gassing rate of battery, so that the liquid-leakage preventing security performance of battery descends.
In sum, lack that a kind of cost is low, the continuous discharge performance of battery is good, battery liquid-leakage preventing security performance well do not change simultaneously the cathode additive agent that battery structure can improve the alkaline battery electrical property.
Summary of the invention
Problem to be solved by this invention be in battery cathode, adding of proposing for the deficiencies in the prior art a kind of for reducing battery short circuit temperature, gassing rate and improve that cell safety is explosion-proof, the fluorine-containing nonionic surface active agent of FS-3100 of leak resistance and shelf characteric.
The technical solution adopted in the present invention is: a kind of alkaline battery cathode additive agent, described additive are the fluorine-containing nonionic surface active agent of FS-3100, and the content of described additive is 0.05-0.8wt%, in the total weight of zinc powder in the battery cathode.
The present invention compared with prior art, having following remarkable beneficial effect: FS-3100 is a kind of fluorine-containing nonionic surface active agent, it has very high chemical stability, has the effect that can resist strong oxidizer, strong acid and highly basic, and still can keep good surface activity in solution.Simultaneously it and hc-surfactant compound property are good, composite product have the capillary ability of higher reduction, a small amount of surface tension that just can reduce water-based and solvent-based system that adds, wetting, dispersion, levelling and other surface propertys with this reinforcement material, in battery cathode, added the fluorine-containing nonionic surface active agent of FS-3100, reduced the battery short circuit temperature, improve that cell safety is explosion-proof, gassing rate and leak resistance and shelf characteric.
Embodiment
The inventor is through extensive and deep research, find to the negative pole of alkaline battery add the fluorine-containing nonionic surface active agent of FS-3100 to short circuit temperature, the gassing rate of battery and improve that cell safety is explosion-proof, leak resistance and shelf characteric have beyond thought raising effect.
In addition, battery of the present invention can be selected corresponding positive pole and electrolyte components, and additive of the present invention, negative pole, battery are described as follows.
Anode preparation method
Applicable positive pole of the present invention is not particularly limited, and can be the conventional applicable known positive pole of positive pole, especially technical staff in this area, for example, contains the positive pole of manganese dioxide and graphite powder.
The negative pole of battery
The main active of negative pole is zinc powder, hydrogen or metal hydride, and other elements such as iron, lead or cadmium also can be considered to use under some special-purpose.
The electrolyte of battery
The key component of electrolyte aqueous solution should adapt to positive pole of the present invention and negative pole is formed a team.
Below in conjunction with specific embodiment the present invention is described further, single the present invention not only is confined to following examples.
The comparative example
Prepare negative pole with conventional method, described negative pole does not add the fluorine-containing nonionic surface active agent of FS-3100, and namely concentration is 0wt%, then manufactures experimently into battery.
Embodiment
Be the fluorine-containing nonionic surface active agent of FS-3100 of 0.05wt%, 0.1wt%, 0.2wt%, 0.4wt%, 0.8wt% with concentration, add in the raw material of negative pole, the total weight in zinc powder in the battery cathode obtains negative pole, and described negative pole is manufactured experimently into battery.
Measure the electrical property of this electrode with DM2000 battery intelligent automatic checkout system, measure respectively battery short circuit temperature and explosion-proof quantity, the result is as described in Table 1:
Table 1 adds different content FS-3100 to the impact of battery short circuit temperature and explosion-proof performance
Along with the increase of surfactant FS-3100 addition, the short circuit temperature of battery descends gradually, and when surfactant addition during less than 0.2wt%, the short circuit drop in temperature speed of battery, the short circuit temperature drops to 111 ℃ fast from 170 ℃; After the addition of surfactant surpassed 0.2wt%, the downward trend of short circuit temperature was mild, and the short circuit temperature is in about 110 ℃.
Along with the increase of surfactant FS-3100 addition, rate of explosion also descends gradually, and FS-3100 is increased to 0.2wt% from 0wt% along with surfactant, and rate of explosion drops to 0% from 35%.
Measure respectively performance (being called for short new electricity) and the 70 ℃ of lower performances of placing 7 days that newly make battery with DM2000 battery intelligent automatic checkout system, the result is as described in Table 2:
Table 2 adds different content FS-3100 to the impact of battery electrical property
Add after the FS-3100 nonionic surface active agent, the electrical property of battery has had significant change.In the heavy-current discharge process, the electrical property of new electricity has faint decline, maximum fall is about 3.5%, the electrical property of storing electricity promotes on the contrary to some extent, electrical property is along with the increase of surfactant FS-3100 presents the rear downward trend that rises first, and performance is best when the addition of surfactant FS-3100 is 200ppm; In the small-power discharge process, downward trend after new electricity and the electrical property of storing electricity all promote to some extent electrical property and rise first along with the increase of surfactant FS-3100 presents reaches maximum when the addition of surfactant FS-3100 is 200ppm.May be because surfactant has formed coating layer on the zinc powder surface, reduced the surface activity of zinc powder, quick exchange and the transmission of material have been suppressed, therefore the high power discharge ability of battery weakens to some extent, owing to having reduced the self-discharge rate of zinc powder, increase so that store the electrical property of electricity simultaneously.
Measure the electrical property of this electrode with DM2000 battery intelligent automatic checkout system, measure respectively 70 ℃ of 5 days gassing rates of battery and 90 ℃ of high temperature leakages in 30 days, the result is as described in Table 3:
Table 3 adds different content FS-3100 to the impact of battery gassing rate and high temperature leakage
Along with the increase of surfactant FS-3100, the gassing rate of battery reduces gradually, and during less than 200ppm, the gassing rate decrease speed of battery is fast, from the 0.54mL fast-descending to 0.11mL in the surfactant addition; After the addition of surfactant surpassed 200ppm, the downward trend of gassing rate was mild, is in about 0.09mL.Along with the increase of surfactant FS-3100, high temperature leakage rate also descends gradually, and under 90 ℃ of conditions of 30 days, FS-3100 is increased to 200ppm from 0ppm along with surfactant, and the leakage rate drops to 0% from 33%.
