Problems solved by technology
[0004] However, due to the technical limitations of the continuous expanded grid production equipment, there are no side frames on the left and right sides of the expanded grid.
Experiments have shown that the battery made of expanded grids has a greater risk of short circuit due to the lead paste on the side of the plate falling off during use. If the traditional AGM separator U-shaped cladding structure is used, the side frames of the positive and negative plates have no separators. If the lead paste on the side of the battery falls off during use, it will fall to the bottom of the pole group, which will easily lead to a short circuit of the battery caused by the contact of the positive and negative electrode paste at the bottom of the pole group, thus reducing the service life of the battery

Embodiment Construction
[0025] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] Such as figure 1 , Figure 5 As shown, the AGM bag-type separator cladding structure proposed by the present invention includes a positive electrode plate 1, an AGM separator plate 31 and a negative electrode plate 2, wherein the AGM separator plate is in the shape of a bag, and the positive electrode plate 1 or / and negative electrode plate 2 are arranged in the bag Shaped AGM separator.
[0027] Such as Figure 4 , Figure 5 As shown, use polypropylene (PP) film 32 or glass fiber cloth composited with acid-resistant cloth of PTFE resin to wrap the openings on the left and right sides of the folded double-layer AGM separator 31, and then use polyester thread 33 or PE thread to sew the opening. live, thus forming an AGM pocket separator.
[0028] Such as figure 1 As shown, in this embodiment, when the positive and negative plates are stacked stagg...

The invention discloses an absorbent glass mineral wool (AGM) bag-type separation plate wrapper sheet structure and a production method. The AGM bag-type separation plate wrapper sheet structure comprises a positive electrode plate, an AGM separation plate and a negative electrode plate, wherein the AGM separation plate is of a bag type, and the positive electrode plate or / and the negative electrode plate are arranged inside the bag-type AGM separation plate. The AGM separation plate is made into a bag-type structure with an opening on one end, and the AGM bag-type separation plate is used for wrapping the positive electrode plate and the negative electrode plate, so that the short-circuit problem of a storage battery caused by the contact of the positive electrode plate and the negative electrode plate because the electrode plate drops paste in the application process can be effectively reduced.
Description
technical field [0001] The invention relates to the field of lead-acid storage batteries, in particular to an absorption-type ultra-fine glass wool (AGM) bag-type separator cladding structure and a manufacturing method for preventing battery short circuit. Background technique [0002] In the production process of AGM lead-acid battery semi-finished products, in order to prevent the internal short circuit of the battery caused by the contact of the positive and negative plates of the battery, prevent the deformation of the plates and cause the active material to fall off, reserve the necessary electrolyte, and provide oxygen circulation channels, etc., it is necessary to The positive and negative plates are clad, and then the positive and negative plates are stacked alternately to form an electrode group. The traditional cladding method, such as U-shaped longitudinal fixed-length separator (the length direction of the separator is parallel to the direction of the tab), doubl...
