Problems solved by technology

[0003] Depend on Figure 1-a and Figure 1-b It can be seen that the positive column 10 and the negative column 4 of the cylindrical maintenance-free sealed lead-acid battery conduct current through wires. Since the wires are only suitable for small current transmission, the cylindrical maintenance-free sealed lead-acid battery cannot realize high-current discharge. , it is difficult to apply in the field of high-capacity batteries

Abstract

The embodiment of the invention discloses a storage battery, which comprises a battery shell, a battery cover plate and a battery body, wherein the battery body is born inside the battery shell; the battery shell is cylindrical or elliptically cylindrical; the battery body comprises a positive plate, a negative plate distributed together with the positive plate at a certain interval, a positive bus bar connected with the positive plate, and a negative bus bar connected with the negative plate; a membrane is lined between the positive plate and the negative plate; and the battery cover plate is provided with a positive terminal connected with the positive bus bar, a negative terminal connected with the negative bus bar, a liquid injection hole for injecting an electrolyte, and a pressure safety valve for sealing the storage battery. The technical scheme provided by the invention can be applied in the field of large-capacity batteries, and can be used for realizing large-current discharge.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a storage battery. Background technique [0002] Such as Figure 1-a and Figure 1-b It is respectively a side view and a cross-sectional top view of an existing cylindrical maintenance-free sealed lead-acid battery, which includes a casing 7, a cover sheet 2, a battery core 6, a positive plate 10, a negative plate 8, an adsorption material 5, an electrolytic The liquid 13 and other parts are characterized in that the positive plate 10 and the negative plate 8 arranged in the housing 7 are arranged vertically and alternately, and the middle is lined with a separator 9. The positive pole 12 and the negative pole 4 are arranged on the upper part of the shell 7. The negative pole The post 4 is respectively connected to the battery core 6 and the bottom metal base plate 11 through wires, and the positive pole 12 is connected to the positive copper cap 1 through a wire. [0003] Depend on ...
