Abstract
The invention discloses a positive grid of a lead-acid accumulator, which comprises a titanium alloy substrate and a pure lead plating layer. The titanium alloy comprises the following components in percentage by weight: 41.74-44.64% of Ti, 11.93-13.41% of Zr, 26.95-29.22% of V, 6.92-7.57% of Mn and 9.54-11.62% of Cr, wherein, the thickness of the pure lead plating layer is 2.1-3.6mm. The pure lead and the titanium alloy in the positive grid are fully moistened and firmly combined, have no layering, peeling and passivating phenomena after being certain charged and discharged, are not corroded by electrolyte solution, and have no difference with the original grid after the pure lead is renewedly plated when a lead layer is removed; and the materials can be recycled, thus Increasing resource utilization rate and reducing environment pollution. The positive grid has obvious progress compared with the traditional positive grid made of lead alloy and titanium materials.
Description
Technical field
The present invention relates to a kind of positive grid of lead-acid accumulator, belong to lead acid accumulator plate grid material field.
Background technology
Lead acid accumulator is widely used, and performance requirement is more and more higher.Grid in its electric core, particularly the selection of material of positive grid is most important.Traditional lead acid accumulator adopts aluminium alloy with positive grid, owing to there are impurity elements such as iron in the aluminium alloy, they can be that electrolyte medium forms primary cell with sulfuric acid, thereby cause the grid corrosion, and this material high temperature performance in the battery use is poor, the grid of making can not be recycled after using, waste resource, contaminated environment.Have research to point out that Titanium can be used as positive grid material, but there is the passivation tendency in titanium as positive grid material, and blunt titanium can not wettingly plate, easily peel off.
Summary of the invention
The object of the present invention is to provide a kind of electrolyte that is not subjected to corrode, can improve the positive grid of lead-acid accumulator of resource utilization, reduction environmental pollution.
Technical scheme of the present invention is: positive grid of lead-acid accumulator is to be made of the titanium alloy-based end and pure lead-coat, the component of described titanium alloy and weight percent content are: Ti 41.74%～44.64%, Zr 11.93%～13.41%, V 26.95%～29.22%, Mn 6.92%～7.57%, Cr 9.54%～11.62%, the thick 2.1～3.6mm of described pure lead-coat.
Adopt above technical scheme, on the titanium alloy-based end plating pure plumbous as positive grid, plumbous and base material abundant wetting combine firm, after 1500 all charge and discharge cycles, layering do not have peel off, passivation phenomenon, pure lead can not produce the primary cell effect, avoids being subjected to electric corrosion.Utilize to quicken the anodal strong charging/discharging thereof that destroys, reach predetermined all numbers after, the lead of removing former plating plates pure lead again, the indistinction on the apparent and performance with former grid, the recyclable utilization of material improves resource utilization, reduces environmental pollution.This positive grid is used to make lead acid accumulator, replaces traditional positive grid of aluminium alloy or the positive grid of titanium, and marked improvement is arranged.
Embodiment
Further specify the present invention below by specific embodiment.
