Abstract

The invention provides a bipolar lead-acid storage battery, which belongs to the technical field of storage batteries and solves the problem of poor performance of an existing bipolar lead-acid storage battery. The bipolar lead-acid storage battery comprises a shell and a top cover, wherein bipolar plates are arranged in the shell; the inner cavity of the shell is divided into a plurality of compartments by the bipolar plates; a battery monomer is arranged in each compartment; the shell is provided with a cover plate; the lower side surface of the cover plate is in sealing connection with the bipolar plates, and the upper side surface of the cover plate is in sealing connection with the top cover; the cavity of the top cover is divided into air chambers; a plurality of air chambers and a plurality of compartments correspond one by one and are communicated via through holes; and each air chamber is independently connected with a check valve. By use of the bipolar lead-acid storage battery, the battery monomers are protected from the interflowing of electrolyte while an active substance use ratio is guaranteed, the performance of the storage battery is improved, and meanwhile, the service life of the storage battery is improved.

Description

technical field

[0001] The invention belongs to the technical field of accumulators and relates to a bipolar lead-acid accumulator. Background technique

[0002] Lead-acid battery is a kind of battery whose electrodes are mainly made of lead and its oxide, and the electrolyte is sulfuric acid solution. Lead-acid battery is mainly composed of positive plate, negative plate, electrolyte, separator, battery tank, battery cover, etc. The top of the lead-acid battery has a plastic sealing cover with ventilation holes.

[0003] For example, the Chinese Utility Model Patent Application (Application No.: 200920112517.4) discloses a bipolar lead-acid battery, including a casing, a positive terminal piece and a negative terminal piece drawn from the casing, and a sealed battery cover with a one-way valve. On the two side walls of the inner cavity of the housing, there are respectively provided positive and negative terminal plates parallel to each other, a layer of positive active ma...
