Abstract
The utility model discloses an ultra-thin grid negative plate of a sealed lead-acid storage battery, which takes a metal grid as a main body, one edge of the metal grid is connected with a metal foil as a lug, and the surfaces of the metal grid and the metal foil are plated with lead; the utility model discloses the active material quantity is few, the high-usage, has alleviateed the weight of polar plate and the weight of whole battery, has reduced the degree of corrosion and the sulfation phenomenon of polar plate, has prolonged the life of battery, can use low density electrolyte, "rich liquid" design, has solved the inhomogeneous problem of the whole group service voltage of battery effectively.
Description
Technical field
The utility model relates to a kind of accumulator plate.
Background technology
The use of motive-power battery belongs to big electric current degree of depth charge and discharge cycles substantially, the positive plate seriously corroded, in the market more and more by the electric bicycle that consumers in general accepted, employing be exactly this kind minitype motivation type sealed lead acid storage battery.
Owing to be subjected to the restriction of cell volume, need in less thickness space, hold many board-like pole plates and barrier film, the grid of this employing gravity casting, one minimum requirement is arranged on technology, can't further reduce the thickness of negative grid, so the thin thickness of positive plate, corrosion resistance is low.Again because pole plate has tied up a large amount of battery spaces, void volume is minimum, can only add a spot of electrolyte, for satisfying the amount of electrochemical reaction desired substance, reach capacity requirement, have only the density that increases electrolyte, the sulfuric acid of high concentration, increased the extent of corrosion of electrode, increased the probability that early stage capacitance loss appears in battery, made that the useful life of battery is not long.
Summary of the invention
The purpose of this utility model is: the ultra-thin grid negative plate that a kind of sealed lead acid storage battery is provided, adopt the ultra-thin grid structure of metal grill surface lead plating, make that the active material consumption is few, utilance is high, can alleviate the weight of pole plate and the weight of entire cell, the gravimetric specific energy height of battery, void volume in the battery is big, can use low-density electrolyte, reduce the extent of corrosion and the sulphation phenomenon of pole plate, prolong the useful life of battery, can realize " pregnant solution type " design, solve problems such as the inhomogeneous and electrolyte of the whole group of battery working voltage early dries up effectively.
The technical solution of the utility model is: a kind of ultra-thin grid negative plate of sealed lead acid storage battery, described negative plate are based on metal grill, and an edge of metal grill is connected with tinsel as lug, and the surperficial lead plating of metal grill and tinsel.
Described metal grill can be made with copper mesh, aluminium net, punched copper tape, punching aluminium strip and foam metal, and described tinsel can be made with Copper Foil or aluminium foil.
The utility model has the advantages that:
1. negative pole of the present utility model adopts the ultra-thin grid structure of metal grill surface lead plating, and the active material consumption is few, utilance is high, has greatly alleviated the weight of pole plate and the weight of entire cell, the gravimetric specific energy height of battery.
2. ultra-thin negative pole structure of the present utility model increases the void volume in the battery, uses low-density electrolyte, has reduced the extent of corrosion and the sulphation phenomenon of pole plate, has prolonged the useful life of battery.
3. the utility model uses low-density electrolyte, " pregnant solution type " design, has solved problems such as the inhomogeneous and electrolyte of the whole group of battery working voltage early dries up effectively.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 metal grill; 2 tinsels.
Embodiment
Embodiment: as shown in Figure 1, a kind of ultra-thin grid negative plate of sealed lead acid storage battery, described negative plate is based on metal grill (1), and an edge of metal grill (1) is connected with tinsel (2) as lug, and the surperficial lead plating of metal grill (1) and tinsel (2).
Described metal grill (1) can be made with copper mesh, aluminium net, punched copper tape, punching aluminium strip and foam metal, and described tinsel (2) can be made with Copper Foil or aluminium foil.
The ultra-thin negative plate that the utility model utilization special process is made, the utilance of negative electrode active material is higher, the only requirement that needs thin negative electrode grid and less active material just can satisfy capacity, and traditional gravity casting grid, slab lattice thickness has a minimum requirement, can't achieve the above object, the result has caused negative electrode active material excessive, tie up the cell body space, increase battery weight, strengthen material cost.
Ultra-thin negative plate design of the present utility model, only need a small amount of pole plate just can satisfy requirements such as capacity, promoted the void volume that the battery cell body holds electrolyte, use the electrolyte of low concentration, the extent of corrosion and the sulphation phenomenon of pole plate have been reduced, and can realize " pregnant solution type " design, at the motive-power battery characteristics that deep discharge uses of charge deeply, " pregnant solution type " also solved effectively the whole group of battery working voltage inhomogeneous with problems such as electrolyte early dries up.
Claims (5)
1. the ultra-thin grid negative plate of a sealed lead acid storage battery, it is characterized in that: described negative plate is based on metal grill (1), one edge of metal grill (1) is connected with tinsel (2) as lug, and the surperficial lead plating of metal grill (1) and tinsel (2).
