Abstract
The invention relates to a method for preparing lead storage batteries, particularly to a method for preparing lead-antimony alloy grids for lead acid batteries. Metals gadolinium and yttrium as well as a lead-antimony alloy are mixed to be prepared into electrode substrates of storage batteries, so that when the electrode substrates are applied to the lead acid batteries, the phenomenon that the conductivity of electrodes is affected due to the fact that antimony released by positive electrodes of traditional electrode substrates gathers on negative electrodes is effectively avoided, the conductivity and the corrosion resistance of the storage batteries are improved, and meanwhile, the service life of each lead acid battery is effectively prolonged.
Description
Technical field
The present invention relates to a kind of method preparing lead accumulator, particularly relate to a kind of method preparing storage battery electrode substrate.
Background technology
At present, the huge challenge of facing mankind environment and re-sources, especially oxycarbide discharge capacity grows with each passing day, cause serious air pollution, as greenhouse effect, especially in the recent period haze weather covers whole China the earth, and to daily life and healthyly bring very large harm, many one of the main reasons of above-mentioned pollution that causes are motor vehicle exhaust emissions.
Due to, the current automobile overwhelming majority adopts gasoline engine or diesel engine as power, and its can burn in the middle of operation a large amount of gasoline or diesel oil, discharge the multiple air pollution sources such as a large amount of carbon dioxide, sulfide simultaneously; Although all having formulated the many kinds of measures such as such as restricting the number to reduce the multiple place of motor vehicle exhaust emission, reducing the use of automobile, all having cured the symptoms, not the disease; In order to reach the object of effecting a permanent cure, present knowledgeable people proposes to use electric motor car to carry out alternative traditional fuel-engined vehicle, but because the restriction of current battery technology, causes the capacity of battery, useful life etc. all cannot meet the requirement of people's long-distance travel and transportation cost.
Current lithium battery, Ni-MH battery, fuel cell or the lead-acid batteries etc. of using are as the power source of electric automobile, but the little price of the specific energy due to ni-mh is high, fuel cell not only price superelevation and its critical material life-span also shorter, then can there is the costliness that its price of certain potential safety hazard also compares in use in lithium battery; And then make the range of application of above-mentioned lithium battery, Ni-MH battery and fuel cell very limited.
So, present electric automobile mainly adopts lead acid accumulator as its power source, although lead acid accumulator has excellent performance and cost performance, but it requires to have very strong corrosion resistance as the electrode base board of the key element of lead acid accumulator, and the active material on its surface also will have good electric conductivity simultaneously.
Traditional lead acid accumulator generally adopts lead-antimony alloy to carry out the preparation of electrode base board, but along with the growth of battery-using time, moisture collection speed wherein can be accelerated, can make positive electrode substrate discharges a large amount of antimony, and the antimony that these discharge also can be gathered on negative electrode substrate, and then greatly reduce the electric conductivity on electrode base board surface, cause the combination property of storage battery to reduce.
Summary of the invention
For overcoming above-mentioned deficiency, the invention provides a kind of preparation method of lead-acid battery lead-antimony alloy grid, the anode plate grid using the method to prepare, has good electric conductivity and decay resistance.
To achieve these goals, the invention provides a kind of method preparing storage battery electrode substrate, be applied in the preparation work of lead acid accumulator, described method comprises the steps:
Lead-gadolinium foundry alloy and lead-yttrium foundry alloy are provided;
Lead-antimony alloy is provided;
After described lead-gadolinium foundry alloy, described lead-yttrium foundry alloy and described lead-antimony alloy being fused together, casting forms described storage battery electrode substrate.
In above-mentioned method, in described lead-antimony alloy, also comprise rare earth.
In above-mentioned method, in vacuum environment, be under the condition of 950 ~ 1000 DEG C in temperature, described lead-gadolinium foundry alloy, described lead-yttrium foundry alloy and described lead-antimony alloy are fused together.
In sum, the preparation method of a kind of lead-acid battery lead-antimony alloy of the present invention grid, storage battery electrode substrate is prepared after metal gadolinium, yttrium being mixed with lead-antimony alloy, and then make this electrode base board when for lead-acid battery, the antimony effectively avoiding the positive pole release that traditional electrode base board occurs is gathered in negative level, and then affect the phenomenon of electrodes conduct ability, while raising storage battery electric conductivity and decay resistance, also effectively extend lead acid accumulator useful life.
Embodiment
The preparation method of a kind of lead-acid battery lead-antimony alloy of the present invention grid, can be applicable in the preparation work of lead acid accumulator, and in the preparation technology of especially lead-antimony alloy electrode base board, the method comprises the steps:

Secondly, above-mentioned lead-gadolinium foundry alloy, lead-yttrium foundry alloy are added in the lead-antimony alloy under molten condition, can be fused together uniformly to make its three, and continue the casting process of battery pole plates, both after the mixture of above-mentioned molten condition having been cast in the mould of corresponding storage battery electrode substrate, after cooling in vacuum environment, final acquisition storage battery electrode substrate.
Finally, the preparation technology that lead acid accumulator is follow-up is continued, to obtain final lead acid accumulator.
Preferably, in above-mentioned lead-antimony alloy, also comprise rare earth so that better and lead-gadolinium foundry alloy, lead-yttrium foundry alloy melting, and then improve the performance of electrode base board of follow-up preparation.
Preferred d, under vacuum conditions, adopts the temperature of 950 ~ 1000 DEG C, above-mentioned lead-gadolinium foundry alloy, lead-yttrium foundry alloy and lead-antimony alloy is fused together uniformly.
