Description
Technical field
The utility model relates to a kind of lead-acid battery double polarity plate.
Background technology
Battery specific capacity manufactured by lead acid accumulator carbon back bipolar plates reaches 55 Wh/kg, improves 30%-40% than existing common batteries, and designed life, 3-8, improve 2-3 doubly than common batteries.But, arrange run through the consistency of the conductive pin of carbon back bipolar plates and stability more difficult, conductance and the corrosion resistance of acusector are still problem.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art and provides a kind of specific capacity that can improve lead-acid battery, strengthen mechanical strength and the active material adhesive force of carbon back bipolar plates, the lead-acid battery double polarity plate of the weak point avoiding existing bipolar plates to exist in configuration aspects.
In order to achieve the above object, the utility model is achieved in that it is a kind of lead-acid battery double polarity plate, it is characterized in that comprising:
Carbon back bipolar plates; Positive and negative two pole-faces of described carbon back bipolar plates are provided with the sunk area caved inward, are provided with " ten " font boss of more than two in described sunk area, upper and lower two " ten " font boss are interspersed;
Battery paster layer; Described battery paster layer is coated in sunk area;
Glass layer; On positive and negative two pole-faces that described glass layer is attached to carbon back bipolar plates and clad battery is coated with layer of paste; And
Upper nonmetal card article and lower nonmetal card article; Described nonmetal card article is installed on the upper end of carbon back bipolar plates and glass layer, and upper nonmetal card article is provided with liquid injection hole, and the upper end of liquid injection hole can be in communication with the outside, and the lower end of liquid injection hole is communicated with the upper end of carbon back bipolar plates and glass layer; Described lower nonmetal card article is installed on the lower end of carbon back bipolar plates and glass layer.
Horizontal direction in described sunk area and vertical direction are respectively equipped with horizontal stiffener and vertical stiffeners.
The utility model advantage is compared with prior art: the specific capacity that can improve lead-acid battery, strengthens mechanical strength and the active material adhesive force of carbon back bipolar plates, and the intensity of carbon back bipolar plates is large, not cracky.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model;
Fig. 3 is the stereogram of carbon back bipolar plates of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.It should be noted that at this, the explanation for these execution modes understands the utility model for helping, but does not form restriction of the present utility model.In addition, if below in described each execution mode of the utility model involved technical characteristic do not form conflict each other and just can be combined with each other.
In the utility model describes, term " on " and the orientation of the instruction such as D score or position relationship be based on orientation shown in the drawings or position relationship, it is only the utility model instead of require that the utility model with specific azimuth configuration and operation, therefore can not must be interpreted as restriction of the present utility model for convenience of description
In description of the present utility model, term " first " and " second " only for describing object, and can not be interpreted as instruction or hint relative importance.
As shown in Figures 1 to 3, it is a kind of lead-acid battery double polarity plate, comprising:
