Technical field
The utility model relates to a kind of battery components, is specifically related to a kind of high-performance lead-acid accumulator grid.
Background technology
The positive and negative grid of lead acid accumulator, is generally in mould, to be cast into latticed thin plate with lead or the lead alloy of molten state, is called grid, sees Fig. 1.What in Fig. 1,1a identified is the lug part of grid, and what in Fig. 1,2a identified is the outer frame part of grid, and what in Fig. 1,3a identified is the collector body part of grid.During battery discharge, collector body is the lug part to grid by the current delivery of collecting, and realizes the transmission of inside battery electric current.
The lead-acid battery that adopts this class grid to make, volume is large, Heavy Weight, active material utilization is low, specific energy is low, is the weak point of lead acid accumulator maximum.The Main Function of grid is the carrier of active material on pole plate and the conduction that realizes inside battery electric current, and itself does not participate in electrode reaction.Therefore, adopting light-duty grid material to replace traditional grid to reduce battery weight, improve battery specific energy, is a kind of effective solution.
Summary of the invention
The technical problems to be solved in the utility model is, solves traditional lead acid accumulator plate grid heavier, and the problem that active material utilization is low provides a kind of lightweight, and specific energy is high, and internal resistance is little, the high-performance lead-acid accumulator grid of long service life.
The utility model solves the technical scheme that its technical problem adopts: construct a kind of high-performance lead-acid accumulator grid, comprise lug, frame and Lead Foam collector body, described lug is fixed on the outside of frame, it is inner that described Lead Foam collector body is arranged on described frame, described Lead Foam collector body marginal portion and described frame portion are overlapping, described Lead Foam collector body is connected with described frame by the mode of electro-deposition, and the edge of described Lead Foam collector body and described frame are become integral body by the metal of electro-deposition parcel.
In technique scheme, described lug and frame are connected and fixed by die casting is one-body molded.
In technique scheme, described lug thickness is 1～2.5mm.
In technique scheme, the thickness of described frame is 1～2.5mm.
In technique scheme, the thickness of described Lead Foam collector body is 1～10mm.
In technique scheme, the percent opening of described Lead Foam collector body is 85%～90%, and the diameter of inner galvanized wire is 0.8～1.2mm.
Implement high-performance grid of the present utility model, there is following beneficial effect:
1, the utility model utilizes the principle of metal ion cathodic reduction, and lug, frame and Lead Foam collector body are fixed together.Marginal portion and the frame portion of Lead Foam collector body are overlapping, and form effective connection by the method for electro-deposition.The edge of Lead Foam collector body and frame are become integral body by the metal of electro-deposition parcel, the junction good conductivity of Lead Foam collector body and frame, and reliability is high, has improved the performance of battery grid;
2, Lead Foam collector body has unique Three Dimensions Structure, and its surface area is huge, is the more than ten times of the common grid of equal volume.It and active material contact area are larger, and it is shorter that electronics is delivered to the distance of grid, and therefore, active material utilization is higher, and the internal resistance of cell is lower.Owing to having so huge specific area, the corrosion electric current density on grid also reduces greatly, has extended the useful life of grid and battery.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of lead acid accumulator plate grid in prior art;
Fig. 2 is the structural representation of the utility model Lead Foam battery grid.
Embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
Referring to Fig. 2, the utility model high-performance lead-acid accumulator grid comprises lug 1b, frame 2b and Lead Foam collector body 3b.
The utility model utilizes the principle of metal ion cathodic reduction, and lug 1b, frame 2b are connected, are fixed together with Lead Foam collector body 3b.Marginal portion and the frame 2b of Lead Foam collector body 3b partly overlap, and form effective connection by the method for electro-deposition.The edge of Lead Foam collector body 3b and frame 2b are become integral body by the metal of electro-deposition parcel, the junction good conductivity of Lead Foam collector body 3b and frame 2b, and reliability is high, has improved the performance of battery grid.
Lead Foam collector body 3b has unique Three Dimensions Structure, and its surface area is huge, is the more than ten times of the common collector body of equal volume.It and active material contact area are larger, and it is shorter that electronics is delivered to the distance of grid, and therefore, active material utilization is higher, and the internal resistance of cell is lower.Owing to having so huge specific area, the corrosion electric current density on grid also reduces greatly, has extended the useful life of grid and battery.
High-performance battery grid in the present embodiment, Lead Foam collector body 3b is that percent opening is 85%～90%, and the diameter of galvanized wire is 0.8～1.2mm, and sheet metal thickness is 6mm, and weight is 300g.Can be made into the polar plate of lead acid storage battery that a slice capacity is 50Ah.If the grid of producing by common gravity casting method, makes the suitable pole plate of a slice capacity, its grid weight is more than 400g.Adopt this high-performance lead-acid accumulator grid, same capability battery grid weight can reduce by 25%.
By the tie point between metallography microscope sem observation Lead Foam collector body 3b and frame 2b, Lead Foam collector body 3b and frame 2b, be rolled into for an integral body by the metallic lead of electro-deposition.On whole frame 2b, there are hundreds of tie points, the current delivery of enough collector body 3b being collected, to the lug 1b of grid, makes it to become a slice high-performance lead-acid accumulator grid.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing from the scope situation that aim of the present invention and claim protect, also can make a lot of forms, within these all belong to protection of the present invention.
