Detailed Description

For a better understanding of the objects, structure and function of the present utility model, an AGM lead acid battery according to the present utility model will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 shows an AGM lead-acid battery according to a preferred embodiment of the present utility model, namely, a lean solution type battery, comprising a battery pack case 1, the battery pack case 1 having a plurality of upwardly open pack slots 11, preferably six pack slots 11 in this example, two pack slots 11 equipped with pole group 2 are shown for ease of understanding, respectively a first pack slot 11-1 and a second pack slot 11-2, and the remaining four pack slots 11 are effect charts when pole group 2 is not assembled; the first assembly groove 11-1 and the second assembly groove 11-2 are inserted with the pole group 2, and the outer surface of the pole group 2 is coated with the protective interlayer 3; the purpose of the coating of the protective barrier 3 is to facilitate the smooth insertion of the pole group 2 into the assembly groove and to protect the battery plates 21 at both edges of the pole group 2 from scratches.

Specifically, the electrode group 2 is formed by alternately stacking a plurality of battery electrode plates 21 and AGM separators 23, electrodes 22 are led out from the upper parts of the battery electrode plates 21, two battery electrode plates 21 are arranged on two sides of the electrode group 2, and before the electrode group 2 is assembled into the assembly groove 11 of the battery assembly shell 1, extrusion compression is required, otherwise, the electrode group 2 cannot be fed into the assembly groove 11 by the thickness of the electrode group 2; however, if the protection interlayer 3 of the present embodiment is not used to cover the electrode group 2, the electrode group 2 is directly extruded and inserted into the assembly groove 11, the battery plates 21 at two edges of the electrode group 2 will be scratched, and meanwhile, the electrode group 2 is not easy to be sent into the assembly groove 11, which results in time and labor waste for assembly.

Because the AGM lead-acid storage battery is characterized in that the expansion rate of the AGM separator 23 is larger, professional equipment is adopted to compress the pole group 2, the thickness of the battery polar plate 21 is unchanged, only the thickness of the AGM separator 23 is changed, in order to ensure that the battery polar plates 21 on two sides of the pole group 2 are not scratched, preferably, a special protection interlayer 3 is adopted, the whole pole group 2 is wrapped up from the bottom and is compressed by professional compression equipment, and then assembled after being compressed to a certain thickness, however, the protection interlayer 3 has a smooth outer surface, the smoothness of the outer surface is not affected after the compression, so that the battery polar plates 21 on two sides of the pole group 2 can be smoothly fed when the pole group 2 is forcefully extruded into the assembly groove 11, and meanwhile the protection interlayer 3 can also protect the battery polar plates 21 on two sides of the pole group 2 from being scratched.

In the AGM lead-acid storage battery, the AGM separator is made of superfine glass fibers, has certain mechanical strength, ensures the requirements of mechanical production and use, is used as an isolation layer for separating the positive plate and the negative plate of the lead-acid storage battery, prevents the positive plate and the negative plate of the lead-acid storage battery from being short-circuited and prevents positive active substances from falling off, and meanwhile, the AGM separator is also a porous material, and can adsorb and fix enough electrolyte in the lead-acid storage battery to enable the electrolyte to be in a relatively high saturated state so as to ensure the discharge capacity of the battery.
