Problems solved by technology

In fact, the two have their own advantages and disadvantages. The external formation is thorough, and the formation temperature, concentration, and plate quality are easy to control, while the internal formation is more difficult in the initial formation, the internal temperature of the battery may be uneven, and the consistency of the battery is slightly poor.

Embodiment 1

[0039] In one embodiment of the present invention, a 12V horizontal bipolar gel battery is prepared. Such as figure 1, 2 , 3, first lay a piece of negative unipolar sheet 1 horizontally in the battery cell 8 where the negative terminal 7 is located, and then add horizontal bipolar sheets 3 in the adjacent cells 9 and 10, and the positive end of the bipolar sheet is located at In cell 9, the negative end is located in cell 10, and then another horizontal bipolar sheet 3 is added to cells 11 and 12. As mentioned above, the positive and negative electrodes can be alternated; A piece of tubular positive monopole sheet 2 is spread in the cell 13 . So far, the first layer or the bottom pole piece of the horizontal bipolar gel battery has been assembled;

[0040] Next, add one deck of AGM diaphragm 5 on the pole piece in each cell 8-13, lay the first diaphragm layer;

[0041] Then, lay up the second layer of bipolar sheets, and add horizontal bipolar sheets 3 in the single cells ...

Embodiment 2

[0045] In another embodiment of the present invention, a 6V horizontal bipolar gel battery is prepared, such as Figure 5 Shown is a side view of another electrode assembly of a horizontal bipolar battery. For a single cell at the current lead-out end, four tubular negative unipolar sheets 1 and three tubular positive unipolar sheets 2 are used for assembly. . Its assembly operation is basically the same as that described in Example 1, the difference is that the pole plates of the bottom and the top layer are all composed of a single negative plate (or positive plate) and a negative pole end (or positive pole end) of a bipolar plate, and the opposite positive and negative poles Add one deck of PVC separators 5 between them, and positive and negative are stacked alternately. The horizontal bipolar sheets 3 between adjacent cells are connected by the positive and negative vertical connecting strips 19 of the bipolar sheets to form a horizontal bipolar sheet group to evenly dist...

Abstract

The invention discloses a horizontal dual-polar pipe type colloid storage battery and a preparation method thereof. The horizontal dual-polar pipe type colloid storage battery is assembled by adopting a horizontal dual-polar structure and comprises a tubular polar plate, a colloid electrolyte and a lead-acid storage battery with single lattices assembled with dual injection holes, wherein polar sheets between the single lattices of the horizontal dual-polar pipe type colloid storage battery are horizontally placed, namely that one or more porous acid-resistant diaphragms are tiled on one negative electrode, then one positive electrode is tiled, and finally the negative electrode, the porous acid-resistant diaphragms and the positive electrode are sequentially assembled. Meanwhile, a positive electrode plate (or negative electrode) of the former lattice is horizontally connected with a negative electrode plate (or positive electrode) of the adjacent lattice, and a connected region is sealed by using paraffin, AB epoxy resin glue, ABS (Acrylonitrile Butadiene Styrene) butanone and the like or an acid-resistant sealing ring part for isolating an electrolyte among the lattices. According to the horizontal dual-polar pipe type colloid storage battery, the specific energy of the horizontal dual-polar pipe type colloid storage battery can be effectively improved, and the service life of the horizontal dual-polar pipe type colloid storage battery is prolonged.

Description

technical field [0001] The invention relates to a bipolar storage battery and a preparation method thereof, in particular to a horizontal bipolar gel storage battery and a preparation method thereof. Background technique [0002] Lead-acid batteries are the earliest and most widely used rechargeable secondary batteries. However, compared with other new batteries such as lithium-ion batteries, they have disadvantages such as short life and relatively low specific energy, which limits its development. In fact, lead-acid batteries have many obvious advantages, especially their high current discharge capacity, overcharge and overdischarge resistance, safety, extremely mature technology, wide range of raw materials, and low prices. Therefore, how to solve the above shortcomings has always been an important issue in the battery and even the energy industry. At present, the industry generally starts from several important aspects: [0003] On the one hand, improve the battery str...
