Abstract

The utility model relates to a bipolar battery. The bipolar battery comprises a case, a polar plate, a busbar, a terminal and electrolyte, wherein a safety valve is arranged on the upper surface of the case, the polar plate comprises a positive plate and a negative plate, a baffle plate is arranged between the positive plate and the negative plate, the negative plate, the baffle plate and the positive plate are sequentially arranged to form a group of clusters, the electrolyte fills in the inner part of the case through the safety valve, and each of the positive plate and the negative plate is provided with two lugs which are arranged at opposite angles. The bipolar battery has the advantages that the lugs are arranged on the positive plate and the negative plate of the bipolar battery, the two lugs are arranged at opposite angles, so that two groups of positive electrodes and negative electrodes are led out after the positive plate and the negative plate are overlapped in a crossing manner; therefore, the resistance of electric quantity led in or led out by a lug in the prior art is reduced to half, the distance between active matters on the polar plate and each lug is reduced to half, only the reactions of active substances at the two ends of the polar plate are consistent, the softening and vulcanization of the active substances are reduced to half, the charge frequency of the battery is reduced, and the service life of the battery is prolonged.

Description

Bipolar cell

Technical field

The utility model relates to a kind of bipolar cell, belongs to lead acid accumulator field.

Background technology

Conventional lead acid accumulator is one pole battery at present, this battery outward appearance has a positive pole and a negative pole, what inner correspondence connected is a positive lead terminal and a negative lead terminal, be connected respectively to positive bus and negative bus, be connected respectively to positive plate and negative plate, electrode plate structure is all to only have a plate ear, and the electric current of full wafer pole plate disperses and collects is all to import and derive (referring to Fig. 1 to Fig. 4) through plate ear.There is following shortcoming in prior art one pole battery: owing to there being Ohmic resistance characteristic apart from distance, resistance close to plate ear is little, the electric current of sharing is many, resistance away from plate ear is large, the electric current of sharing is few, and like this, the active material close to plate ear charges and overdischarge long-term existence, so active material is easily loose softening, even inner plumbous rib is all corroded disconnected; From the long-term charge less electricity of active material away from plate ear, discharge also incapable, so active material easily forms more lead sulfate, finally sulfuration, being poorly conductive, even lost efficacy.

Summary of the invention

The purpose of this utility model is to overcome deficiency and the defect that prior art exists, and a kind of bipolar cell is provided.

The technical solution of the utility model is: a kind of bipolar cell, comprise the shell of sealing, pole plate, bus-bar, terminal and electrolyte, the upper surface of described shell is provided with safety valve, described pole plate just comprises, negative plate, just, between negative plate, be provided with dividing plate, described negative plate, dividing plate shape and positive plate are arranged in order one group of cluster of composition, described electrolyte is filled into enclosure by described safety valve, described enclosure arrange two groups described in cluster, the first cluster and the second cluster stacked arrangement, make the positive plate of the first cluster relative with the negative plate of the second cluster, and the positive plate of the second cluster is provided with a negative plate corresponding thereto, a described pole plate left side, right both sides are respectively equipped with lug, and two lugs are symmetrical arranged along pole plate horizontal center line, described bus-bar is connected with lug, each cluster left side, right both sides are just being respectively equipped with one group, negative bus and just, negative terminal, described two groups just, negative terminal is drawn from the shell left and right sides respectively, and with just, negative plate is corresponding to be connected.

In above-mentioned bipolar cell, on described positive and negative terminal, corresponding position mark has positive and negative sign.

In above-mentioned bipolar cell, described shell is formed by plastic injection-moulded.

The beneficial effects of the utility model are:

1, the pole plate of the utility model bipolar cell is provided with lug, two lugs are in diagonal distance, after positive/negative plate juxtaposition, will draw like this two groups of both positive and negative polarities, the resistance that an original like this plate ear imported or derived electric weight just reduces one times, active material on pole plate just reduces one times from plate ear distance, pole plate only has two ends being reaction consistent, being softens and sulfuration reduces one times, increase cell charging times, extend battery, take 6-DZM-20 lead acid accumulator as example: discharging current is 10A, charging is charged with charger for electric bicycle, prior art plumbic acid one pole battery and bipolar cell cycle life of the present invention are contrasted, comparing result is in Table 1.

2, the utility model bipolar cell leading-out terminal is two positive poles and two negative poles, and external connection is more firm, avoids current interruption phenomenon completely, and line resistance reduces one times simultaneously, and two groups of external wiring terminals are beneficial to battery large current charge and electric discharge.

3, the inner every pole plate upper plate ear of the utility model bipolar cell is two, and this structure is beneficial to large current charge and electric discharge, and being reaction promptness is greatly enhanced.
