Description
Technical field
The utility model relates to power supply manufacturing technology field, in particular to a kind of corrosion-resistant cathode confluence component.This is practical
It is novel to further relate to a kind of non-maintaining valve-regulated sealed lead-acid batteries including above-mentioned corrosion-resistant cathode confluence component.
Background technique
Now, technological innovation of the domestic and international new energy field in directions such as energy storage, communication, power rapidly develops, for storing
The technical research of battery is gradually deepened.The corrosion resistance of lead-acid storage battery busbar has directly the service life of lead-acid accumulator
Connect influence, according to the principle of electrochemical reaction of lead-acid accumulator, negative bus-bar most vulnerable to corrosion, positive bus by
Corrosion it is weaker, therefore, domestic and international industry it is corrosion-resistant to the busbar connector of lead-acid accumulator research also just focused on cathode confluence
On row.
Currently, commonly using lead-acid accumulator in industry both at home and abroad is broadly divided into two major classes: rich solution type, lean solution type, it is specifically, rich
Liquid type is other solid assembling parts such as the pole group that removing pole plate, partition form in the battery case of battery and busbar connector, pole
Remaining space be completely filled with electrolyte, electrolyte is in excessive state more than needed, and electrolyte is in the state for flooding busbar connector more；It is poor
Liquid type generally refers to non-maintaining valve-regulated sealed lead-acid batteries, without bright acid inside battery case, is also divided into industry
Common lead-acid accumulator, gelled lead acid battery, the electrolyte of common lead-acid accumulator are generally sulfuric acid, and colloid lead acid storage battery
Pond is the improvement to common lead-acid accumulator, has been replaced sulfuric acid electrolyte with colloidal electrolyte, using gel electrolyte,
Inside exists without free fluid, and electrolyte is not easy lamination occur.
There are mainly four types of existing non-maintaining valve-regulated sealed lead-acid batteries busbar connector method for anticorrosion-treating: first is that adopting
With the busbar connector of corrosion resisting alloy material, delay the corrosion of busbar connector, this method is applied widely, is not only suitable for common plumbic acid and stores
Battery is also applied for gelled lead acid battery, but higher cost；Second is that injecting and adhering to around the busbar connector of lead-acid accumulator
Upper gel-like electrolyte is isolated the contact of busbar connector and oxygen in ambient gas, prevents from aoxidizing the acceleration for corrosion, but the party
Method is generally chiefly used in gelled lead acid battery, and the scope of application is small；Third is that directly brushing attached one on the busbar connector surface of lead-acid accumulator
Layer epoxide-resin glue, is isolated the contact of busbar connector and oxygen in ambient gas, prevents from aoxidizing the acceleration for corrosion, this method is suitable
It is wide with range, it is not only suitable for common lead-acid accumulator, is also applied for gelled lead acid battery, but epoxide-resin glue shakes in battery
It is easy to be cracked when dynamic or busbar connector deforms and loosens disengaging, busbar connector anticorrosion effect is bad.
In conclusion how to realize that non-maintaining valve-regulated sealed lead-acid batteries negative bus-bar is corrosion-resistant, and can ensure
Non-maintaining valve-regulated sealed lead-acid batteries have good cost performance, and being that current those skilled in the art are urgently to be solved asks
Topic.
Summary of the invention
In view of this, the purpose of the utility model is to provide a kind of corrosion-resistant cathode confluence component, which converges
The busbar connector of stream component has corrosion resistant advantage, and can ensure that non-maintaining valve-regulated sealed lead-acid batteries have good sexual valence
Than.The another object of the utility model is to provide a kind of including the non-maintaining valve-regulated sealed of above-mentioned corrosion-resistant cathode confluence component
Lead-acid accumulator.
In order to solve the above technical problems, the utility model provides a kind of corrosion-resistant cathode confluence component, including it is set to storage
Pole group, negative bus-bar and the negative terminal being welded on the negative bus-bar inside battery case, the cathode confluence
Partition is covered on row, partition one end set is hung on the negative terminal, the partition other end and pole group upper surface
It is in contact.
Preferably, the negative bus-bar is pure lead material.
Preferably, the negative terminal is one of Pb, Sn material or a variety of.
Preferably, the partition is AGM partition.
The utility model also provides a kind of non-maintaining valve-regulated sealed lead-acid batteries, including accumulator housing and setting
Corrosion-resistant cathode confluence component inside the accumulator housing, the corrosion-resistant cathode confluence component is such as any of the above-described
The corrosion-resistant cathode confluence component.
Corrosion-resistant cathode provided by the utility model converges component, partition is covered on negative bus-bar, partition is by connecing
The one end for touching pole group surface can absorb electrolyte, thus guarantee that partition is tightly covered on negative bus-bar surface in moisture state,
The contact of negative bus-bar and oxygen in ambient gas is isolated, prevents from aoxidizing the acceleration for corrosion, effectively cathode is delayed to converge
The corrosion of row.Even if partition one end set, which is hung over, can ensure that battery vibration or negative bus-bar change is occurring in partition on negative terminal
Negative bus-bar surface is still closely covered on when shape.The negative bus-bar using corrosion resisting alloy material is compared in the use of partition,
It is substantially reduced in the investment of cost, can ensure that non-maintaining valve-regulated sealed lead-acid batteries have good cost performance.Meanwhile
Negative bus-bar use pure lead material, can avoid negative bus-bar in when containing Sn segregation caused by intercrystalline corrosion, and because Pb with
Pb-Sn current potential differs very little, and the galvanic effect of negative bus-bar and cathode intercolumniation is negligible, to realize that cathode converges
Flow the whole anticorrosion effect of component.
The utility model also provides a kind of non-maintaining valve-regulated sealed lead-acid including above-mentioned corrosion-resistant cathode confluence component
