Embodiment 1

[0035] Embodiment 1: see figure 1 , figure 2 The present invention first adopts the continuous belt-shaped lead cloth material produced by the process of "physical vapor deposition-electrodeposition-heat treatment" or "conductive paint coating-electrodeposition-heat treatment", and coats positive electrode paste 2 and negative electrode lead paste on both sides of the lead cloth. Paste 3, be coated with macromolecule insulating acid-resistant coating 5 in the middle, as commercially available epoxy resin coating. Then cut into required specifications of bipolar plates and monopolar plates. In the special fixture, two bipolar plates 1 and one unipolar plate are placed on the first layer, and three bipolar plates are placed on the second layer, or each bipolar plate or unipolar plate is separated by ultrafine glass fiber The board is AGM wrapped, and so on, and the number of stacked layers depends on the battery capacity to be assembled. AGM partitions 4 are placed between l...

Embodiment 2

[0036] Example 2: see image 3 , Figure 4 , the continuous strip-shaped lead cloth material produced by "physical vapor deposition-electrodeposition-heat treatment" or "conductive paint coating-electrodeposition-heat treatment" technology, cut into the required size grid, and coated on both sides respectively Cover positive electrode paste or negative electrode paste to form positive electrode plate 6 or negative electrode plate 7, put a positive electrode on the special fixture, put a separator 4 on it, then put a negative electrode, and put a separator or positive electrode plate on the negative electrode 1. The negative plate is wrapped with ultra-fine glass fiber separator AGM, and so on. The number of plates depends on the capacity of the assembled battery, and then the frame is used to fix the pole group. The ends of the positive and negative electrodes are welded together with bus bars, vertically or horizontally. Put it in the battery slot.

Embodiment 3

[0037] Embodiment 3: see Figure 5 , Figure 6 , using the "physical vapor deposition-electrodeposition-heat treatment" or "conductive paint coating-electrodeposition-heat treatment" process technology to produce continuous strip-shaped lead cloth materials, cut into long strip grids of required specifications, and place them on the positive and negative electrodes Use the different positions of the grid to weld the lead pole pieces 8 by roll welding, then apply positive lead paste and negative lead paste respectively to make positive plate 6 and negative plate 7, and the active material is coated on both sides of the grid. On the special jig, put an AGM separator 4 slightly wider than the pole plate, then put the positive electrode, then put an AGM separator, and finally put the negative electrode, wind them together and put them into the battery tank 9, and roll the positive and negative electrodes. The protruding parts of the pole pieces are welded together with bus bars 1...

Abstract

The invention discloses a process for making lead fabric battery using new pattern lead fabric material as pole plate slab lattice, wherein a physical vapour deposition or electrically-conducting paint coating - electrodeposition -heat treatment combination process is applied, in the production, the lead fabric material may be used in various forms, e.g. double pole plates, the two ends of the lead fabric are coated with positive, negative electrode lead grease, the central portion is coated with macromolecular insulation acid resisting paint, the bipolar pole plates' positive and negative electrodes are placed horizontally in an overlapping mode, a glass fiber baffle plate is arranged in the center. The structural pattern of the invention can take various types, the advantages of the invention are small internal impedance and great current charging and discharging.

Description

technical field [0001] The invention relates to a battery in the field of electricity, in particular to a method for manufacturing a lead cloth battery using a new type of lead cloth material as a battery plate grid. Background technique [0002] Currently used valve-regulated sealed lead-acid batteries are composed of alternately placed positive and negative plates, diaphragms, electrolytes, battery tanks, covers, and poles. [0003] The positive and negative plates are first cast into grids with lead alloy, and then the grids are filled with positive paste and negative paste, and then made through acid leaching, curing, drying and other processes. This kind of grid as an active material carrier requires ① good electronic conductivity for large current discharge; ② good bonding strength between the grid and the active material to resist the shrinkage and expansion of the positive and negative active materials of the battery during charging and discharging , to prevent the ...
