Technical Field

[0001] The utility model relates to the field of lead-acid batteries, in particular to a polar plate for a lead-acid battery. Background Art

[0002] Lead-acid batteries are a common type of battery. Their electrodes are primarily made of lead and its oxides, while the electrolyte is a sulfuric acid solution. Plates are the fundamental components of batteries, receiving and dissipating electrical energy. Plates are categorized as positive and negative. Lead-acid battery plates are made of a lead-antimony alloy grid coated with an active material.

[0003] The existing lead-acid battery plates have too single functions and a short service life. During use, they suffer severe wear and tear. At the same time, each plate is separated by a partition, which not only increases the thickness of the battery but also has no protective effect. Moreover, the partition reduces the contact area between the plate and the electrolyte, reducing the battery capacity and battery service life.

[0004] Therefore, it is necessary to invent a lead-acid battery pole plate to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a lead-acid battery plate, which is inserted into a sheath by using sliders on both sides through the positive plate and the external first outer frame and the negative plate and the external second outer frame, so as to not only play a protective role, but also replace the existing separator between the positive plate and the negative plate, not only reducing the thickness of the lead-acid battery, but also increasing the contact area with the electrolyte, thereby increasing the overall service life of the lead-acid battery, so as to solve the problems raised in the above-mentioned background technology.

[0008] The second outer frame is installed in the sheath and is used to protect the negative electrode plate. The first negative electrode connector is fixedly installed on one side of the upper part of the second outer frame, and the second negative electrode connector is fixedly set on the other side of the upper part of the second outer frame. The negative electrode plate is set inside the second outer frame, and the positive electrode connection group is set above the second negative electrode connector.

[0009] Preferably, sliders are fixedly mounted on both sides of the first outer frame and the second outer frame, sliding grooves are provided on both side surfaces of the inner portion of the sheath, and the first outer frame is slidably connected to the second outer frame and the sheath.

[0010] Preferably, the positive plate includes an anti-corrosion layer and an insulating layer. The anti-corrosion layer is arranged inside the positive plate and the negative plate. The surface of the positive plate and the negative plate is provided with an insulating layer. The material of the anti-corrosion layer is carbide, and the material of the insulating layer is polyolefin film.

The positive electrode plate 9 is connected to the external first outer frame 4 and the second outer frame 11 outside the negative electrode plate 14, and is inserted into the sheath 1 using sliders 5 on both sides. It not only plays a protective role, but also replaces the existing separator between the positive electrode plate 9 and the negative electrode plate 14, not only reducing the thickness of the lead-acid battery, but also increasing the contact area with the electrolyte, thereby increasing the overall service life of the lead-acid battery.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, sliders 5 are fixedly installed on both sides of the first outer frame 4 and the second outer frame 11, and slide grooves 3 are provided on the inner two side surfaces of the sheath 1. The first outer frame 4 is slidably connected with the second outer frame 11 and the sheath 1. The first outer frame 4 and the second outer frame 11 slide in the sheath 1 through the sliders 5 on both sides, and the sheath 1 replaces the existing partition to reduce the thickness of the lead-acid battery.

[0031] like Figure 4 and Figure 5 As shown, the interior of the positive plate 9 includes an anti-corrosion layer 901 and an insulating layer 902. The anti-corrosion layer 901 is arranged inside the positive plate 9 and the negative plate 14. The surface of the positive plate 9 and the negative plate 14 is provided with an insulating layer 902. The material of the anti-corrosion layer 901 is carbide, and the material of the insulating layer 902 is polyolefin film. The anti-corrosion layer 901 arranged inside the positive plate 9 and the negative plate 14 is made of carbide, which provides overall corrosion resistance and avoids excessive density of the internal electrolyte, which causes corrosion of the positive plate 9 and the negative plate 14. The insulating layer 902 arranged on the surface of the positive plate 9 and the negative plate 14 is made of polyolefin film, which avoids discharge between the plates and causes damage to the capacitor.

[0032] like Figure 3 and Figure 4 As shown, the bumps 10 are respectively arranged on both sides of the positive plate 9 and the negative plate 14. The bumps 10 are distributed at equal intervals on both sides of the positive plate 9 and the negative plate 14. The arrangement of the bumps 10 strengthens the firmness of the positive plate 9 and the negative plate 14.

[0033] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, a socket sleeve 17 is provided below the negative electrode connection group 15 and the positive electrode connection group 16, and a slot 18 is provided inside the socket sleeve 17.

[0034] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, an insert block 8 is provided inside the first positive terminal 6, the second positive terminal 7, the first negative terminal 12, and the second negative terminal 13.

[0035] The working principle of the utility model is as follows: first, the first outer frame 4 outside the positive plate 9 and the second outer frame 11 outside the negative plate 14 are respectively inserted into the sheath 1, and the sliders 5 on both sides of the first outer frame 4 and the second outer frame 11 are limited and slid into the sheath 1. The protrusions 10 on the outside of the positive plate 9 and the negative plate 14 strengthen the firmness of the positive plate 9 and the negative plate 14, and the first outer frame 4 and the second outer frame 11 replace the existing separator, which not only reduces the thickness of the lead-acid battery, but also increases the contact area with the electrolyte, thereby increasing the overall service life of the lead-acid battery. Then, the negative connection group 15 and the positive connection group 16 are respectively aligned with the first positive terminal 6 and the second positive terminal 7 and the first negative terminal 12 and the second negative terminal The connector 13 and the slot 18 inside the socket sleeve 17 are inserted into the outside of the plug block 8. After the negative connection group 15 and the positive connection group 16 connect the first positive connector 6 and the second positive connector 7 and the first negative connector 12 and the second negative connector 13, the entire plate is installed on both sides of the acid battery. When the acid battery is in use, the anti-corrosion layer 901 provided inside the positive plate 9 and the negative plate 14 is made of carbide, which provides overall corrosion resistance and prevents the internal electrolyte density from being too high, causing corrosion of the positive plate 9 and the negative plate 14. The insulating layer 902 provided on the surface of the positive plate 9 and the negative plate 14 is made of polyolefin film, which prevents discharge between the plates and damage to the capacitor. In this way, the use process of the lead-acid battery plate is completed.
