Description
Technical field
The present invention relates to the electric bicycle field, particularly a kind of preparation method of electric bike battery grid alloy.
Background technology
In recent years, the pollution that environment is produced from motor vehicle and the reason of energy growing tension, and the city inside road aggravation of blocking up, people are in the research that steps up the high-performance electric bicycle.The performance-critical of electric bicycle is its core---storage battery, considers from fail safe, performance and price and technology maturity, and lead acid accumulator remains the most economical and the most practical electrical source of power of electric bicycle.Electric bicycle battery is main mainly with the medium current continuous discharge with dark circulation.Press the actual instructions for use of power battery, higher than fixed battery request to the specific energy of electric bicycle battery with dark cycle life index.Because the plumbous calcium series alloy grid material of former use is applicable to the floating charge state and uses, not anti-deep discharge circulation, in order to improve the dark cycle life of battery, most battery manufacturing enterprise tends to adopt plumbous antimony series alloy.But because the etching problem of common low antimony alloy in the battery cyclic process; And antimony moves the thermal runaway bulging problem that produces after the caused battery dehydration from positive pole dissolving to negative pole, and a lot of electrokinetic cell manufactories have adopted the method for adding cadmium in the lead-antimony alloy in manufacture process.Cadmium exists organism can not the injury of reparation property, as a kind of product for civilian use, Pb-Sb-Cd alloy make and use, in the discarded process, cadmium will cause great injury to environment, this influence to environment has caused a lot of knowledgeable people's worry.
People were studying the composition of grid alloy always in recent years; Many scholar's research other element that in the Pb-Ca-Sn-Al alloy, mixes; Expectation makes lead-calcium alloy keep that existing processing technology is good, the gassing overpotential high, on the basis of low cost and other advantages, possess the performance that better anti-deep discharge recycles.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of preparation method of electric bicycle lead accumulator grid alloy of corrosion-resistant and anti-deep discharge circulation.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of preparation method of electric bike battery grid alloy, said alloy is made up of following component by weight percentage: Bi:0.03-0.07%, Cu:0.05-0.08%; Ce:0.10-0.15%, Sn:1.0-2.0%, Ca:0.10-0.20%; Al:0.02-0.04%, Ag:0.08-0.15%, Pb surplus; Said preparation method is: earlier electrolytic lead is melted in lead melting furnace, and be warmed up to 730-750 ℃, in plumbous liquid, add metallic aluminium, lead bronze intermediate alloy, plumbous calcium intermediate alloy, plumbous cerium intermediate alloy respectively by proportioning then; Bismuth metal, metallic tin, argent stir after the fusing fully; The adjustment pouring temperature is poured in the grid mould and gets final product to 610-630 ℃.
The interpolation of aluminium has reduced the loss of calcium, refinement crystal grain, reduced production cost.Though the solubility of metallic aluminium in fusion of lead is minimum, in solid-state lead, be almost equal to zero,, aluminium is essential as the auxiliary additive of lead-calcium alloy, otherwise will cause a large amount of scaling loss of calcium, and production cost is significantly increased.The adding of aluminium can make the burn out rate of calcium reduce more than 50%, and when the existing of aluminium, calcium content can not change in 36 hours basically in alloy.
Improve the tin content in the lead-calcium alloy, can improve the conductivity of grid interfacial corrosion layer, reduce rate of corrosion,
The adding of copper has simultaneously also strengthened the decay resistance of alloy.The adding of copper has improved CURRENT DISTRIBUTION, has improved the electrode active material utilance, and has improved high electric rate discharge specific energy by a relatively large margin.In addition, because the copper coin grid have strengthened mechanical strength, resistance to vibration raising, the life-span of battery are prolonged.The adding of copper can impel the PbO of grid/reactive species interface when charging
2Formation, thereby improved the conductivity of storage battery corrosion layer, the dry state passivation phenomenon of the deep-circulating performance that has improved storage battery when storing.
Add the deep discharge cycle performance that silver has obviously improved the mechanical strength of grid, anti-creep ability and storage battery.
Beneficial effect of the present invention is following:
Alloy of the present invention has higher corrosion resistance, and better deep-circulating performance more is applicable to as the electric bicycle power accumulator.Alloy has higher liberation of hydrogen overpotential for oxygen evolution, makes battery accomplish the hermetically sealed possibility that becomes.Alloy has good casting character and mechanical performance.
