Abstract
The invention discloses a storage battery provided with a bipolar polar plate, which comprises a polar plate base body and an active material loaded on the base body. The front surface and the back surface of the base body are respectively provided with crossed slant U-shaped grooves; the opening of the slant U-shaped groove on the front surface is slant upwards, and the groove is filled with a positive active material; the opening of the slant U-shaped groove on the back surface is slant downwards, and the groove is filled with a negative active material. Due to the pocket-shaped structure design, the positive active material is not easy to fall off in the charge-discharge process even in expansion so as to guarantee the stability of the polar plate charge-discharge performance. The base body is manufactured by casting alloy materials of lead-calcium-tin-aluminum, rare earth, and the like. Compared with the base body manufactured by the traditional titanium alloy casting technology, the production cost can be effectively reduced, the process operation difficulty can be reduced and the probability of generating air hole can be reduced, so that the product quality can be guaranteed.
Description
Technical field
The present invention relates to storage battery, be specifically related to be provided with the storage battery of double polarity plate.
Background technology
Bipolarity is for unipolarity, the just corresponding polarity of pole plate of traditional lead-acid battery, positive pole or negative pole have two polarity usefulness and bipolarity is a pole plate, promptly coat positive active material and negative active material respectively at the front and back of a parent plate.The tangible advantage of bipolarity is exactly to have reduced the weight of pole plate number and bus-bar, and for example: the minimum monomer voltage of unipolar lead-acid battery is 2V, and ambipolar monomer adds two unipolar plates by a bipolarity matrix and constitutes 4V.More as can be known, if make the battery of 6V, then unipolarity is wanted six blocks of plates of three monomers, bipolarity only need corresponding two unipolar plates in two bipolarity both sides totally four get final product.String in addition between the bipolarity monomer, current path is short, and internal resistance is little, can provide higher voltage with smaller volume, and specific power promotes.But the storage battery quantity that is provided with double polarity plate in the market seldom, even have, also there is following deficiency: the structural design imperfection of double polarity plate, basal body structure is simple, coat positive active material and negative active material in the groove on both sides respectively, coming off easily owing to expanding in the positive active material charge and discharge process influences the charging efficiency of whole Battery pack.In addition, the matrix of double polarity plate generally adopts the manufacturing of titanium alloy pouring technology, and cost is too high, and is not easy to operate, and its moulding is bad, pore, trachoma is arranged, corrosion-resistant.
Summary of the invention
In order to overcome the defective of prior art, the invention provides the storage battery that is provided with double polarity plate, expands in charge and discharge process with the positive active material that solves the Polar plate matrix that prior art exists come off easily, cost height, operation easier greatly, pore trachoma arranged and cause problem such as corrosion-resistant.
The present invention is achieved through the following technical solutions:
Be provided with the storage battery of double polarity plate, the active material that comprises the carrying of Polar plate matrix and matrix, its section of described Polar plate matrix is continuous serpentine bending, the front and back of matrix 1 is offered staggered oblique U type groove respectively, wherein the oblique U type channel opening offered of matrix front is filled out in the groove and is covered positive active material obliquely; The oblique U type channel opening that the back side is offered is oblique down, fills out in the groove and covers negative active material.
The further improvement project of the present invention is, described matrix 1 wall thickness is 0.6 mm-1.2mm, and after the oblique U type groove projection that matrix (1) is positive, the back side is offered was overlapping, the distance between the notch was 5 mm-7mm.。
The oblique U type groove vertical angle 50o-55o that described matrix front, the back side are offered, the shaping and demoulding gradient is 2o-3o.
In the middle of the described matrix two perpendicular muscle are set, matrix is divided into three equal parts, perpendicular muscle width is 0.8mm-1.2mm.
Described matrix is alloy materials such as lead, calcium, tin, aluminium, rare earth, uses novel extrusion process to make.
The present invention compared with prior art has following obvious advantage:
(1) because the front and back of Polar plate matrix of the present invention is offered staggered oblique U type groove respectively, and the positive oblique U type channel opening of offering obliquely, fill out in the groove and cover positive active material, just because this is similar to the structural design of " pocket " shape, though positive active material through the also difficult drop-off that expands, guarantees the stable of screen charge-discharge performance in charge and discharge process.
(2) the plumbous calcium tin of matrix adopting of the present invention aluminium adds alloy materials such as rare earth, use novel extrusion process to make, the matrix of making by pouring technology than traditional titanium alloy, can reduce production costs, reduce the technological operation difficulty, reduce the probability that produces pore trachoma, thereby guarantee product quality.

Fig. 1 is double polarity plate floor map of the present invention (illustrates and fill out this one side of covering positive active material).
Fig. 2 is Figure 1A-A cross-sectional schematic.
Embodiment
As shown in Figure 1, 2, be provided with the storage battery of double polarity plate, comprise Polar plate matrix 1.As shown in Figure 2, the section of described matrix 1 is continuous serpentine bending, and wall thickness is 0.6 mm-1.2mm, and its front and back is offered staggered oblique U type groove respectively.
Wherein the oblique U type channel opening offered of matrix 1 front obliquely, oblique U type groove vertical angle 50o-55o, the shaping and demoulding gradient is 2o-3o, fills out in the groove to cover positive active material 2.The oblique U type channel opening that matrix 1 back side is offered is oblique down, oblique U type groove vertical angle 50o-55o, and the shaping and demoulding gradient is 2o-3o, fills out in the groove to cover negative active material 3.After the oblique U type groove projection that matrix 1 front, the back side are offered was overlapping, the distance between the notch was 5 mm-7mm.
As shown in Figure 1, in the middle of the matrix 1 two perpendicular muscle 4 are set, matrix is divided into three equal parts, perpendicular muscle 4 width are 0.8mm-1.2mm.
Described matrix 1 adopts plumbous calcium tin aluminium to add alloy materials such as rare earth, uses novel extrusion process to make.
