Abstract

A dual-polar ear storage battery is provided, which comprises a positive dual-polar ear plate, a negative dual-polar ear plate, a shell body, an upper, lower, left and right cover on the shell body. A polar ear is positioned at the same time on the symmetrical side of the positive polar plate or negative polar plate with polar ear; a unit storage battery or a compound battery is provided with two positive and two negative polar. During application, the two positive polar are connected in parallel and the two negative polar are connected in parallel too. Therefore, during the charging or discharging process, the current on the polar plate is balanced and symmetric, so as to effectively improve the heavy current charging and discharging, enhance the utilization rate of active material, prolong the service life of storage battery, reduce the application cost, economize material resources and protect the environment.

Description

Bipolar ear storage battery

Technical field

The utility model relates to the storage battery class, applies to square acid cell or alkaline battery, specifically is a kind of bipolar ear storage battery.

Technical background

Be born till now from acid or alkalescence square (except cylindrical) storage battery, form storage battery positive/negative plate all be that a rectangle or a foursquare one side have only a lug, all have only a positive pole and a negative pole to form by unit storage battery or battery pack that positive/negative plate became, the performance of the storage battery accumulators of this structure has been brought many limitation: 1, when the storage battery heavy-current discharge, internal resistance sharply increases, voltage and current sharply descends, can not fully emit electric weight in moment, make the pole heating, accumulator housing damages, and has limited the scope of application; 2, can not large current charge, because electric current is excessive, polarization resistance moment increases, and makes the polarization resistance of lug P position be converted into heat, thereby makes the pole heating, damages storage battery, can not make storage battery finish charging at short notice; 3, because causing, the structure of pole plate self can not make full use of the utilance decline that active material makes active material; 4, have a strong impact on the useful life of storage battery, particularly high type storage battery, power type accumulator battery, enclosed type accumulators etc., after storage battery discharges end at every turn, all can not return to the preceding capacity of discharge, be cost as returning to that life-span and the too much consumes energy that will sacrifice contaminated environment and storage battery of the strong capacity of battery discharging.Causing above reason under the certain situation of fabrication process condition and service condition mainly is current imbalance and asymmetric during because of charging of storage battery accumulator plate that this body structure causes and discharge, because the lug of every rectangle or foursquare positive/negative plate is all on a limit on four limits of pole plate, this just means that storage battery is when discharge, the electric current on its excess-three limit all flows towards one side that lug is arranged, and when charging, all electric currents also can only be by the three limits motion of one side that lug is arranged to other, finish the output and the input of storage battery, original pole plate just exists from the near resistance of lug just little, the resistance far away from lug is just big, for the pole plate of high type storage battery, the resistance on the one side on lug opposite is just bigger.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency; when a kind of discharging and recharging is provided; current balance type on the pole plate and symmetry; effectively improve large current charge and heavy-current discharge; improve the utilance of active material, prolong the battery-operated life-span, reduce use cost; save materials and equipment resources, the bipolar ear storage battery of protection environment.

The technical solution of the utility model is achieved in that a kind of bipolar ear storage battery, the body and the lid that comprise storage battery, form by the loam cake on just bipolar ear pole plate, negative bipolar ear pole plate, body and the body thereof and lower cover or You Gai and left side lid, have lug symmetry on one side to have additional a lug on one side on the positive plate of storage battery or negative plate, a unit storage battery or an assembled battery are provided with two positive poles and two negative poles.

Bipolar ear battery makes to vertical or horizontal, the orientation difference of the constant lid of its body, and when making into when vertical, the lid of body upper end is a loam cake, the lid of body lower end is a lower cover; When making into when horizontal, the lid of upper end is right lid, and the lid of lower end be that a left side is covered.

The utility model is on the positive plate or negative plate of a storage battery, the opposite on a limit of original lug increases a lug on one side, originally a unit storage battery or an assembled battery have only a positive pole and a negative pole, at a unit storage battery or a storage battery group two positive poles and two negative poles will be arranged now.All be anodal in parallel with two simultaneously in use, two negative pole parallel connections.Reaching when discharging and recharging, current balance type on the pole plate and symmetry, thus improve large current charge and heavy-current discharge effectively, improve the utilance of active material, prolong the battery-operated life-span greatly, reduce use cost greatly, save materials and equipment resources, the protection environment.
