Abstract
The present invention relates to an alloy material for sealed lead-acid accumulator slab lattice. The alloy material is formed by adding 0.05 to 0.1% of the ternary alloy of Bi [x] Ga [y] Ag [z] into Pb and Ca alloy, wherein x =0.8-0.85, y =0.05-0.15, and z=0.05-0.1. The alloy material has favorable casting performance, mechanical performance, corrosion resistance and low resistance. Compared with a common pole plate, the forming time of a pole plate made of the alloy can be shortened for 4 to 5 hours under the same condition, and the problem that the capacity of an accumulator made of the Pb and Ca alloy is easy to lower early is overcome. The sealed reflecting efficiency, the capacity, the service life, etc. of the present invention all reach and exceed the requirements of Japanese SBA 2101-88 and SBA 3101-82 standards.
Description
The present invention relates to a kind of alloy material, especially a kind of alloy material for slab lattice that is used for full-sealed lead-acid accumulator.
Lead acid cell has had the history in more than 100 year since coming out, become one of mainstay industry of current secondary cell.Because the common lead acid accumulator needs regular maintenance, occurs problems such as leakage, acid mist often, and its use range is very limited.For this reason, develop the enclosed non-maintenance store battery, become a very active problem in lead acid cell field.Lead-calcium alloy in nineteen thirty U.S.'s Bell Laboratory at first propose, be applied to automobile battery General Motors Overseas Corporation in 1974.Yet the casting properties of this alloy is poor, and the loss of calcium is serious, for this reason, people have carried out number of research projects again, develop the Pb-Ca-Sn alloy, have suitably improved the flowability of alloy, develop the Pb-Ca-Sn-Al alloy again, reduced the loss of calcium in the casting process, but, still existed three main drawbacks with regard to present Pb-Ca-Sn-Al alloy, (1) physical strength of alloy is low, does the large-sized battery difficulty; (2) distortion of anode plate grid is expanded and is caused internal short-circuit of battery; (3) PbsO of anodal surface corrosion product
4The early stage capacity of battery is descended.In order to overcome above-mentioned three big defectives, the someone develops the Pb-Ca-Sn-Al-Na alloy again, promptly adds 0.01～0.02% Na in the Pb-Ca-Sn-Al alloy, to improve the physical strength of alloy, but the overpotential of hydrogen evolution of this alloy descends, and two other shortcoming also fails to overcome.
In addition, another kind of traditional lead-acid accumulator grid alloy material Pb-Sb alloy, its stibiated major advantage is to form PbO between grid and active substance
2, make battery have good cycle performance, it is generally acknowledged not stibiated alloy, can cause the early stage capacity of battery to descend i.e. " no antimony effect ".Yet, if in the Pb-Ca alloy, add Sb, can form the metallic compound of Ca and Sb, this compound is separated out owing to having very high fusing point, not only influences the beneficial effect of Ca, and the corrosion resistance nature of alloy is seriously descended.
The objective of the invention is to propose a kind of scheme that in the Pb-Ca alloy, adds the Bi-Ca-Ag ternary alloy, thereby make the alloy material for slab lattice of novel full-sealed lead-acid accumulator, to overcome the deficiencies in the prior art part.
The object of the present invention is achieved like this.
The alloy material for slab lattice of full-sealed lead-acid accumulator is in the Pb alloy, adds the ternary alloy of being made up of Bi-Ca-Ag and forms.This alloy material composition (weight) is: Ca0.08-0.1%; BixGay Agz 0.05-0.1%, wherein X=0.8-0.85 can be scaled Bi0.04-0.085%, and y=0.05-0.15 can be scaled Ga0.0025-0.015%, and z=0.05-0.1 can be scaled Ag0.0025-0.01%; The Pb surplus.
The present invention adds bismuth alloy and replaces antimony.Because bismuth and antimony are of the same clan, its performance is similar to antimony.But facts have proved that the add-on of bismuth and mode are very big to the alloy performance impact, generally control the bismuth-containing amount 0.14% with.In addition, bismuth easily forms LMP eutectic thing, and suitable alloy is preferably adopted in the adding of bismuth.The present invention makes bismuth gallium silver ternary alloy with bismuth and adds.Gallium can improve the surface energy of alloy effectively, thereby suppresses PbO
2To PbSO
4Conversion.Silver is a kind of very good alterant, and the adding of silver can make the alloying element uniform distribution, but also can suppress Ca, Bi, and the Ga element is separated out to crystal boundary, makes alloy have the superior corrosion resistance energy.Though silver belongs to noble metal, the total amount that adds is very little, can not cause the too big rising of cost of alloy.
Below provide two embodiment of the present invention:
Embodiment 1: " make the Pb-0.08%Ca alloy with common smelting furnace, its temperature is controlled at 500～510 ℃.Make the 85%Bi-10%Ga-5%Ag ternary alloy 400 ℃ the time with crucible furnace, ternary alloy is joined Pb-0.08% in 0.05% ratio, in the Ca alloy, under 500 ℃ ± 10 ℃, be cast into 12V38AH enclosed cell grid then.
Embodiment 2: make the Pb-0.1%Ca alloy, its temperature is controlled at 510 ℃.Preparation 80%Bi-10%Ga-10%Ag ternary alloy, the ratio in 0.1% joins in the Pb-0.1%Ca alloy, and the back casts 12V00AH enclosed cell grid under 500 ℃.
Alloy material of the present invention has good casting properties, mechanicalness Can, decay resistance and lower resistance. The utmost point made from this alloy Plate is under equal conditions compared and can be shortened the time of changing into common pole plate 4-5 hour. Make the surface corrosion product of anode plate grid of this alloy PbO2, overcome the Pb-Ca alloy because the surface corrosion product is PbSO4, the early stage capacity loss of the battery that causes. Close with this The battery grid that gold is made, its airtight reflection efficient reaches 99.7%; Capacity reaches 106AH for the third time, and service life cycle is up to 540 times (60% discharge), constant-voltage charge reaches 720 days, all is higher than far away The SBA2101-88 of Japanese Industrial Standards and SBA3101-82 want Ask.
