Description
Technical field
The present invention relates to electric bicycle field, particularly a kind of system of storage battery grid alloy for electric bicyclePreparation Method.
Background technology
In recent years, pollution environment being produced for motor vehicle and the reason of energy growing tension, and cityThe aggravation of interior congestion in road, people are in the research stepping up the electronic bicycle of high-performance. The property of electric bicycleCan key be its core---battery, examine from security, performance and price and technology maturityConsider, lead-acid accumulator remains the most economical and the most practical electrical source of power of electric bicycle. Electrical salf-walking is automobile-usedBattery is mainly with medium current continuous discharge, deeply to circulate as main. Press the actual operation requirements of electrokinetic cell,Higher than fixed battery request to the specific energy of electric bicycle battery and dark cycle life index. Due toThe plumbous calcium series alloy grid material of former use is applicable to floating charging state and uses, not resistance to deep discharge circulation, forImprove the dark cycle life of battery, most battery manufacture enterprise tends to adopt plumbous antimony series alloy. ButBecause the etching problem of common low antimony alloy in circulating battery process, and antimony dissolves and moves to negative pole from positive poleMove the thermal runaway bulging problem producing after caused battery dehydration, much electrokinetic cell manufactory was manufacturingIn journey, adopt the method for adding cadmium in lead-antimony alloy. There is unrepairable injury to organism in cadmium, asA kind of product for civilian use, Pb-Sb-Cd alloy is in manufacture and use, discarded process, and cadmium will cause the utmost point to environmentLarge injury, this impact on environment has caused a lot of knowledgeable people's worry.
People were studying the composition of grid alloy always in recent years, and many scholar's research are closed to Pb-Ca-Sn-AlOther element that adulterates in gold, expect to make lead-calcium alloy keeping that existing processing technology is good, gassing overpotential is high,On the basis of low cost and other advantages, possesses the performance that better resistance to deep discharge recycles.
Summary of the invention
For the deficiencies in the prior art, one of object of the present invention is to provide a kind of corrosion-resistant and resistance to deep dischargeThe preparation method of the electric bicycle lead accumulator grid alloy of circulation.
For achieving the above object, the technical solution used in the present invention is:
A preparation method for storage battery grid alloy for electric bicycle, described alloy by weight percentage byFollowing component composition: Al:0.04-0.06%, Bi:0.03-0.07%, Ni:0.05-0.10%, Cu:0.5-0.8%, Se:0.10-0.15%, Sn:1.0-2.0%, all the other are Pb; Described preparation method is:
(1) Ni, Cu, Se and Sn are put into crucible, be heated to 1160-1180 DEG C of fusing, stir allEven, pour in ingot mould, obtain ingot casting after cooling for subsequent use;
(2) Al and Bi are placed in lead pan and are smelted, melt and be incubated in 640-660 DEG C; By above-mentioned ingot castingPut into lead pan and continue to smelt, after ingot casting fusing, stir, and standing 15-20min;
(3) adjusting pouring temperature is 540-550 DEG C, is poured in plate grid die, forms grid.
Preparation method's of the present invention beneficial effect is:
1), by optimizing the composition of grid alloy, make in its corrosion product not containing PbSO4, thereby overcomeThe shortcoming of the early stage capacity loss of battery, and its satisfactory mechanical property: hardness number HB17-18kg/cm2; AndAnd there are good casting properties and electric conductivity. Lead-acid accumulator of assembling as plate railings of anode and cathode with itThe 5-6 that 100% dark cycle life is common lead acid accumulator doubly.
2) preparation method of the present invention, by refractory metal and low-melting-point metal melting respectively, controls melting and watersNote temperature, has further ensured the realization of grid alloy superperformance.
Below by detailed description of the invention, the present invention will be further described.
