Embodiment Construction
[0031] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0032] refer to Figure 1 to Figure 9 , which shows a high specific energy valve-regulated lead-acid battery, whose external dimensions are length*width*height*total height=151mm*99mm*99mm*102mm, including upper cover 2, cover plate 1, safety valve 3, Terminal 4, bus bar 5, bottom groove 7, and six pole groups 6 arranged in series. The pole groups 6 are directly connected in series in the bottom groove 7 through the bus bar 5. The groove 7 seals the closed upper cover 2 through epoxy resin, and the connecting terminal 4 is symmetrically welded on the left end of the upper end surface of the upper cover 2. The middle part of the upper cover 2 is provided with a cover plate groove, and the cover plate 1 is closed on the upper cover through the cover plate groove. 2, a safety valve 3 is provid...

The invention discloses a high-specific-energy valve-regulated lead-acid storage battery. The battery comprises an upper cover, a cover plate, a safety valve, a wiring terminal, a busbar, a bottom groove and pole groups, the pole groups are connected in series through the busbar in a direct connection manner, each pole group comprises seven positive plates and eight negative plates which are alternately arranged, each positive plate is wrapped by partition paper from the bottom in a U-shaped mode, each positive plate is located between the negative plates, and the thickness of the negative plates on the outermost sides of the two ends is smaller than that of the other negative plates. The boundary dimension of the storage battery is consistent with that of a 6-DZF-12 battery commonly used in the market at present, and the storage battery can be universally used with a corresponding electric moped; meanwhile, the 2 hr gravimetric specific energy of the storage battery prepared by the preparation method disclosed by the invention can reach 45 Wh / kg, the volumetric specific energy reaches 120 kWh / m<3>, the 100% DOD cycle service life can reach 500 times or more, and the storage battery has relatively high specific energy cycle use performance.
Description
technical field [0001] The invention relates to the technical field of lead-acid battery preparation, in particular to a high specific energy valve-regulated lead-acid battery and a preparation method thereof. Background technique [0002] The lead-acid battery used by the new national standard electric moped is mainly 6-DZF-12 battery, and its battery compartment is designed according to the shape and size of this type of battery; and because of the relatively large number of this type of electric moped, there are many manufacturers , has formed a standard specification, such as the price to be paid for adjustment is relatively large, and the size of the battery compartment that can be placed in the battery is limited. [0003] At the same time, the actual 2hr capacity of existing batteries of this type is generally low and the specific energy is not good, and the service life is short. at 106kWh / m 3 the following. In contrast, most manufacturers increase the capacity of...
