Embodiment Construction

[0034] Such as Figure 1-19 As shown, a bipolar lead-acid storage battery comprises a side positive plate 1, a side negative plate 2, and several bipolar plates 3 between the two, each plate is separated by a separator 4, and the bipolar The two sides of the plate 3 are positive and negative respectively, and each bipolar plate 3 is arranged alternately according to the positive and negative poles. If the positive poles of the bipolar plates 3 at both ends face outward, then the negative plate 2 is placed on the outside of the bipolar plate 3 , the other bipolar plate 3 located at both ends has the negative electrode facing outward, and the positive electrode plate 1 is placed outside.

[0035] Such as Figure 4~6 , 10, 13-15, each bipolar plate 3 includes a positive frame 31 and a negative frame 32, and a lead substrate 33 is sandwiched between the positive frame 31 and the negative frame 32. Both the positive frame 31 and the negative frame 32 can be made of ABS plastic. ...

Abstract

The invention discloses a bipolar lead storage battery. The bipolar plates include a positive frame, a negative frame, and a lead substrate clamped between the positive frame and the negative frame. The frame holes in the middle of each positive frame are filled with positive active materials. , the frame holes in the middle of each negative frame are filled with negative active materials; the opposite sides of the positive and negative frames in the same bipolar plate are provided with a circle of glue grooves, and the outer ring of the glue grooves is also provided with a cooperating first The protruding ring and the first groove, the edge of the lead substrate is located between the glue groove and the first protruding ring. The bipolar plate of the bipolar lead-acid storage battery of the present invention is clamped a piece of lead substrate by positive pole frame and negative pole frame, is used for filling active material in pole frame, and sealant is poured in glue tank between pole frame and lead substrate, seals, The positive electrode frame and the negative electrode frame are sealed by the first protruding ring and the first groove that cooperate with each other, the preparation is simple, and the sealing effect is good.

Description

technical field [0001] The invention relates to the technical field of lead storage batteries, in particular to a bipolar lead storage battery. Background technique [0002] The structure of the traditional lead-acid battery is mainly composed of electrolyte, battery tank and electrode group. The electrolyte of lead-acid battery is sulfuric acid solution. The electrode group is mainly composed of positive plate, negative plate and separator. The separator mainly serves to store the electrolyte. As a gas channel for oxygen recombination, it plays the role of preventing active material from falling off and short circuit between positive and negative electrodes. Generally, the battery tank in a lead-acid battery is divided into multiple cells, and an electrode group is placed in each cell, and lead bridges are used to connect adjacent electrode groups in series. However, the traditional lead-acid battery is limited by its structure, and its specific energy and specific power a...
