Embodiment 1

[0020] In this embodiment, an electric bicycle battery 12v12Ah pole group is taken as an example. like figure 1 , 2 As shown, an electrode group of a valve-regulated sealed lead-acid battery includes negative plates 4 located on both sides of the electrode group, and a separator 3 arranged between the positive and negative plates. still as figure 1 , 2 As shown, the positive and negative plates between the two negative plates 4 are respectively separated by two plates of the same polarity as a group and separated by a separator 3, and the positive plate group 1 and the negative plate group 2 are continuously arranged in order to set Count and end with positive plate group 1, the total number of positive plates and negative plates in each group is equal. The single plate thickness of the positive plate group 1 is 1.5 mm, and the single plate thickness of the negative plate group 2 is 1 mm. The total number of positive plates in the pole group is 12, and the total number of...

Embodiment 2

[0025] The single plate thickness of the positive plate group 1 is 2.5 mm, and the single plate thickness of the negative plate group 2 is 2 mm. The total number of positive plates is 8, and the total number of negative plates is 8. All the other implementations are as in Example 1.

Embodiment 3

[0027] The single plate thickness of the positive plate group 1 is 2 mm, and the single plate thickness of the negative plate group 2 is 1.2 mm. The total number of positive plates is 10, and the total number of negative plates is 10. All the other implementations are as in Example 1.

Abstract

The invention discloses a valve-regulated lead acid storage battery polar group and a polar plate packaging method thereof. The valve-regulated lead acid storage battery polar group comprises positive plates, negative plates and partition plates arranged among the positive plates and the negative plates, and is characterized in that: the polar plates positioned on the two sides of the polar group are negative plates; the polar plates, with the same polarity, of the positive plates and the negative plates between the two negative plates serve as a group and are partitioned by the partition plates; positive plate groups and negative plate groups are continuously arranged in turn to a set number and end with a positive plate group; and in each group, the total number of the positive plates is equal to the total number of the negative plates. The valve-regulated lead acid storage battery polar group improves the active material utilization rate of the valve-regulated lead acid storage battery polar group, simultaneously does not influence the service life of the valve-regulated lead acid storage battery polar group, and reduces the overall cost relatively.

Description

technical field [0001] The invention relates to an electrode group of a lead-acid storage battery, in particular to an electrode group of a valve-controlled sealed lead-acid storage battery and a wrapping method thereof. Background technique [0002] In traditional valve-regulated sealed lead-acid batteries, the way of wrapping the plates in the internal pole group is mostly to use one more negative plate than the positive plate. There are two negative plates on both sides of the pole group, and the positive and negative single-piece plates are used. Interlaced, the positive and negative single-piece plates are separated by a separator, and then the positive and negative tabs are welded in parallel to form a pole group with a rated voltage of 2V, and then several pole groups are connected in series according to the needs. Such as 6V, 12V and other specifications of the battery. [0003] The positive and negative plates used in this battery often have the following problems....
