Abstract
The utility model relates to a composite grid for a positive electrode of high-energy lead-acid accumulator, which is composed of an upper frame, a cross beam and a lead cloth or a foam lead which are successively connected and fixed with each other, wherein the upper edge and the side edges of the upper frame are main transverse ribs, the middle part of the upper frame are vertical ribs and transverse ribs, and the upper frame is fixedly connected with the lead cloth or the foam lead through the cross beam. The utility model concentrates the advantages of a traditional grid and a lead cloth grid and overcomes the disadvantages of the two grids. The utility model has the advantages of light weight, high specific energy, corrosion resistance, small internal resistance, strong electrical transmission ability, long service life and good technical performance.
Description
Technical field
The utility model relates to a kind of battery components, is specifically related to the combined type grid of the anodal usefulness of a kind of high-energy lead-acid battery.
Background technology
Known traditional lead-acid accumulator grid generally adopts gravity casting technology to make, and because of grid is thicker, the storage battery gravimetric specific energy is low.Be to improve the storage battery specific energy, people adopt plumbous cloth material to replace the electrode plate grid of traditional grid as storage battery, and this plumbous cloth generally is to adopt glass fiber mesh or organic fiber net to do base material, deposit in its surface electrical that pure lead or lead alloy make; Also can adopt glass fiber strand or organic fiber tow, make through being woven into net again, also have in addition and adopt the foam-like lead made from physico-chemical process to do grid at its surface extruding parcel lead or lead alloy.The thickness of this plumbous cloth or foam lead is generally between 0.6～2.0mm, available traditional gravity casting mode cylinder manifold in the end casting of the plumbous cloth of certain specification just becomes grid, the weight ratio tradition grid of this grid is light, and therefore the gravimetric specific energy that adopts this grid to make the lead acid accumulator of pole plate increases considerably.It is fully passable that above-mentioned plumbous cloth material uses as negative pole, but when the anode plate grid as storage battery uses, the battery positive voltage grid is in the sulphuric acid environment of electrochemical oxidation, acid solution is infiltrated the interface of grid and active material easily along the junction of grid upper side frame and lead plaster, plumbous cloth is exposed in the electrolyte sulfuric acid near causing the upper side frame bottom, and the warp of plumbous cloth, the lead layer on the parallel are corroded.Because of be corroded attenuate or lead layer of the plumbous cloth in frame bottom or foam stereotype grid top layer lead comes off, grid electrical transmission ability drop, internal resistance increases, battery malfunction.
Summary of the invention
Technical problem to be solved in the utility model is: solve that traditional lead-acid accumulator grid is thick, heavy, the battery specific energy is low, adopt plumbous cloth to replace the problem that plumbous cloth top layer, upper side frame bottom lead is corroded and easily lost efficacy behind traditional grid; And provide a kind of in light weight, specific energy is high, the upper side frame bottom is corrosion-resistant, internal resistance is little, the electrical transmission ability is strong, the combined type grid of long service life, the anodal usefulness of high-energy lead-acid battery that technical performance is good.
The technical solution adopted in the utility model is: the combined type grid of the anodal usefulness of this high-energy lead-acid battery is made of the upper side frame that is connected and fixed successively, crossbeam, plumbous cloth or foam lead, the top of upper side frame and side are main horizontal bar, middle is that perpendicular muscle or perpendicular muscle add horizontal bar, the lower end of upper side frame is connected and fixed crossbeam, and the top of crossbeam and plumbous cloth or foam lead is connected and fixed.
In the technique scheme, the top of upper side frame, crossbeam, plumbous cloth or foam lead is by the die casting one-shot forming and be connected and fixed as a whole.
In the technique scheme, crossbeam thickness is than the little 0.2～2mm of main horizontal bar thickness of upper side frame.
Combined type grid of the present utility model has been concentrated the advantage of traditional grid and plumbous cloth grid, both shortcomings have been overcome, the utility model is because upper side frame master horizontal bar and middle horizontal stroke, perpendicular muscle is thicker, even sulfuric acid infiltrates grid and reactive species interface by the junction of pole plate upper side frame and lead plaster, grid of the present utility model also can bear the electrochemical anodic oxidation corrosion of long period, and the plumbous cloth grid of crossbeam bottom or foam stereotype grid are because the retardance of receptor 1 activity material, galvanized wire is not directly exposed in the electrolyte sulfuric acid environment, a little less than the anodic oxidation corrosion of being born, so can use plumbous cloth or foam lead material to do the anode grid.When using as the battery positive voltage grid, the electric current that the plumbous cloth grid in bottom is compiled is collected by the upper side frame of top tradition grid form structure, and electric current compiles and enters lug.By the grid structure of this combined type, both improved the corrosion resistance of main horizontal bar bottom grid, alleviated the weight of grid integral body again significantly, improved the gravimetric specific energy of storage battery.
