Description

Horizontal bipolar lead battery

The utility model relates to a lead storage battery.

The original lead-acid battery is composed of positive plate, negative plate, bridge, electrolyte and so on. The pole groups are arranged in a straight line and long shape, which occupies a large volume and is extremely difficult to install. It is difficult to weld the battery terminals, and the internal installation of the lead-acid battery is not compact enough.

The purpose of the utility model is to provide a horizontal bipolar lead-acid storage battery with small size, easy installation, improved sealing composite efficiency, and simple welding of battery terminals.

The purpose of this utility model is achieved in the following manner.

The utility model includes a positive plate, a negative plate, a bridge, a glass fiber separator, and an electrolyte. The positive plate and the negative plate are connected through a bridge to form a bipolar plate, and the bipolar plate and the glass fiber separator are interlaced. The pole groups are stacked and assembled, and the terminals use unipolar positive and negative plates respectively. The unipolar positive and negative grids are connected with tabs, and the tabs are inserted into the bus bar for welding. The pole group is tightly arranged, and the pole group is arranged in a U shape as a whole, and the middle of the U shape of the pole group is separated by the middle plate of the inner shell arranged longitudinally.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 2 is a left view of the utility model.

Fig. 3 is a schematic diagram of the expanded U-shaped arrangement of pole groups of the present invention.

Figure 4 is a schematic diagram of a bipolar plate.

Fig. 5 is a schematic diagram of a unipolar positive (or negative) plate.

Referring to accompanying drawing 1,2, shown in 3, the utility model comprises shell 1, inner shell 2, positive pole plate 3, negative pole plate 4, bridge 5, glass fiber dividing plate 6, electrolyte, inner shell intermediate plate 7. Referring to Fig. 4, the positive plate 3 and the negative plate 4 are connected to form a bipolar plate 10 through a bridge 5, the positive plate 3 and the negative plate 4 are attached with a positive active material 8 and a negative active material 9, and the bridge 5 is It is coated with water-increasing and acid-resistant sealing insulating glue, thus solving the problem of series grid short circuit of the pole group. Bipolar plates 10 and glass fiber separators 6 are staggered and stacked to form a pole group 12. The terminals of the utility model respectively use unipolar positive and negative plates (see Figure 5), and unipolar positive (or negative) plates The outer end is connected with a pole lug 11, and the pole lug 11 is inserted into the bus bar 13 and welded, compacted by high pressure, and passed through the positive and negative poles connected on the bus bar. A tooth-shaped inner folder 2 protruding inward is provided in the outer shell 1 to clamp the pole group. The pole group 12 is folded in half in the inner folder 2 and arranged in a U shape. The middle plate 7 of the inner shell inserted in the middle of the inner sandwich shell 2 is isolated.

The working principle of the utility model is that the horizontal bipolar battery is an electrochemical system of Pb/H ₂ SO ₄ /PbO ₂ , and its total electrochemical reaction formula is:

Positive electrode Electrolyte Negative electrode Positive electrode Water Negative electrode

Active material Active material Discharge product Discharge product

When discharging, the electrochemical reaction process is: the lead dioxide (PbO ₂ ) in the positive plate and the velvet lead (Pb) in the negative plate respectively react with the sulfuric acid electrolytic excitation (H ₂ SO ₄ ) to convert the chemical energy into The electrical energy is released, and lead sulfate (PbSO ₄ ) and water (H ₂ O) are generated.

When charging, the electrochemical reaction process is as follows: lead sulfate (PbSO ₄ ) is converted into lead dioxide (PbO ₂ ) and fluffy aluminum (Pb) on the positive plate, and the concentration of lead sulfate (PbSO ₄ ) also increases gradually. , electrical energy is converted into chemical energy and stored.

Because the utility model adopts that the terminal is manufactured through high-pressure unipolar grid with tabs, the problem of difficult terminal welding is solved through high-pressure manufacture.

Since the utility model is equipped with a tooth-shaped inner casing clamping device, the tight equipment of the liquid battery is achieved, and the requirement of anti-vibration is guaranteed. In addition, the U-shaped pole group arrangement is separated by the middle plate of the inner shell between the two pole groups, which makes the installation more convenient for users, reduces the volume, and avoids the phenomenon of short circuit between the pole groups.

In summary, the utility model has the characteristics of convenient installation, small size, easy terminal welding, long service life, fast charging, and good charging capacity.
