Description

Lead-acid storage battery
Technical Field
The utility model relates to a lead acid battery field.
Background
The lead accumulator is widely used in the fields of automobile starting power supply, uninterrupted power supply, power supply and energy storage power supply from electric bicycle to diesel submarine, etc. because of its advantages of stability, reliability, no memory effect, low cost, capacity of being made into single large-capacity battery, etc., its output and energy storage amount are still the first of chemical power supply. The horizontal battery is used as one of lead-acid storage batteries, and because the polar plate of the horizontal battery is horizontally placed in the using process, the layering phenomenon of sulfuric acid electrolyte is effectively reduced. The composite lead wire used in the grid weaving process has the characteristics of good tensile resistance and corrosion resistance, and the ribs of the woven grid are more uniform and dense, so that the high-current charge and discharge performance is stronger. Horizontal batteries have been an elongated structure in a single grid in a "straight" arrangement. The adaptability to the domestic market is extremely low, and some manufacturers make the horizontal battery into two 6V batteries and then serially connect the two batteries from the outside to form a 12V horizontal battery. But one more end face is welded, so that the using amount of lead and tin solder is increased, and the cost is increased. The internal bending type horizontal battery saves external series connection, turns directly inside, has smaller internal resistance and saves lead and tin solder. The cost is lower. The assembly process is simpler, and the safety is higher. The structure of two 6V external serial connections is changed due to the fact that the internal connection is integrated. The overall consistency is better.

Detailed Description
The present invention will be further described with reference to the following detailed description of the embodiments.
A quasi-bipolar horizontal battery comprises a battery case 1, wherein the battery case is provided with a polar plate placing groove 2 and a battery case opening 3, a bent polar plate 4, a bipolar plate 5 and a unipolar plate 6 are placed in the polar plate placing groove, and the polar plate placing groove 2 is formed by the inner wall of the battery case 1 and a partition 10 to form a U-shaped channel. The polar plate 4 of bending is piled up each other by a series of positive negative grids and is formed, positive grid stretches out the direction along utmost point ear 7 and forms positive central line X, negative grid stretches out the direction along utmost point ear and forms negative central line Y, positive central line X with negative central line Y is mutually perpendicular, thereby realizes the utility model aims at. The bent plate 4 is preferably of the same size as the other plates. The utility model discloses a polar plate 4 of bending is 2, also can be 4 or more for needs. The polar plates are isolated by a sealing element 8, the sealing element 7 between the single cells is cast into an I-shaped plastic part, and silica gel sealing strips are embedded at two sides of the plastic part. As shown in fig. 2, the inter-cell sealing element 8 comprises a sealing component 11 coated with silica gel and a channel 12 filled with epoxy glue, the sealing element is used for isolating gas and liquid channels, preventing the inter-cell cross cells from causing short circuit, a tab 9 of a polar plate close to an opening of a battery case extends out of the opening 3 of the battery case and can be cast and welded at one time to form a bus bar, and a side cover is bonded after the tab is welded with a terminal, so that the assembly is completed.
In addition to the above embodiments, the technical features or technical data of the present invention can be selected and combined again within the scope disclosed in the claims and the specification of the present invention to constitute new embodiments, which can be realized by those skilled in the art without creative efforts, and therefore, the embodiments of the present invention not described in detail should be regarded as specific embodiments of the present invention and within the protection scope of the present invention.
