Description

Lead acid accumulator

Technical field

The utility model relates to a kind of lead acid accumulator.

Background technology

Lead acid accumulator is with plumbous and sour secondary cell as active material.Its anodal active material is a brown lead oxide, and the active material of negative pole is a spongy lead, and the electrolyte dilute sulfuric acid all participates in the electrochemical reaction of positive and negative electrode.At first be very fast the consuming of sulfuric acid quilt in the pole plate in the exoelectrical reaction process, the sulfuric acid in the dividing plate is diffused into by concentration difference and continues to participate in reaction in the pole plate, and sulfuric acid and the sulfuric acid in the dividing plate in discharge pole plate in latter stage almost can be consumed totally.

The layering and the concentration polarization of electrolyte are the difficult problem that people can't overcome all the time in the production of lead acid accumulator and use, and the layering of the high more electrolyte of the height of battery is obvious more, the electrical property of battery is poor more, and it directly influences the effective output of the energy content of battery and the useful life of battery.Therefore the layering that solves electrolyte for high type battery is the task of top priority.

In addition, in the battery production process, have to adopt the pole that is unprofitable to battery performance owing to two adjacent both positive and negative polarities need be connected, this has not only reduced battery electrical property, reduce the specific energy of battery, also increased the consumption of lead resource simultaneously, strengthened production cost.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of lead acid accumulator rational in infrastructure is provided, the short circuit problem that can solve the lamination problem of electrolyte in the battery and expand and to cause because of positive pole, reduce the consumption of lead resource simultaneously, improved the specific energy of battery, reduced production cost.

For solving the problems of the technologies described above, the technical solution of the utility model is: lead acid accumulator, comprise battery case, battery cover and be located at the interior battery of battery case, described battery comprises the positive plate and the negative plate of intersecting setting and is used to separate the dividing plate of described positive plate and described negative plate, on described positive plate, be provided with anode ear, on described negative plate, be provided with negative electrode lug, described each positive plate and described each negative plate laterally all around be provided with one the circle dividing plate.

As a kind of optimized technical scheme, described battery cover comprises first battery cover and second battery cover that is arranged at described battery case two ends respectively, described anode ear is located at the relative both sides of described battery respectively with described negative electrode lug, described anode ear is connected with positive bus, described positive bus is connected with positive terminal on described first battery cover, described negative electrode lug is connected with negative bus, and described negative bus is connected with negative terminal on described second battery cover.

After having adopted technique scheme, the beneficial effects of the utility model are:

1. anode ear is located at the relative both sides of battery respectively with negative electrode lug in the utility model, be connected with the upper and lower covers of battery respectively, and each positive plate and each negative plate laterally all around be provided with one the circle dividing plate.Adopting such structure not only to control utmost point group's neat but also prevent battery causes short circuit because of the side of positive/negative plate connects, has eliminated because of positive plate and expanded and elongation causes utmost point group's short circuit; Such structure has shortened the conducting path of electronics simultaneously, the voltage drop loss that minimizing causes because of pole plate resistance, make entire cell obtain unpolarizing preferably, the different parts that is pole plate is charged preferably, reduce concentration polarization and polar plate sulfation, solved electrolyte stratification problem, eliminated battery capacity decay that causes because of electrolyte stratification and the disadvantage that shortens useful life.

2. because the utility model anode ear is located at the relative both sides of battery respectively with negative electrode lug, the anode ear welding is linked to be positive bus, be connected with positive terminal on first battery cover by positive bus, negative electrode lug is connected welding be linked to be negative bus, be connected with negative terminal on second battery cover by negative bus.Therefore the utility model has realized that no pole connects, and has reduced the consumption of lead resource, has improved cost performance of product.
