Abstract
Quadrate lithium battery top cover electrolyte replenishing structure is the utility model is related to, the structure includes cover plate, protective cover, metal funnel and fluid-filling structure, and described fluid-filling structure is located on the cover plate, and fluid-filling structure is made up of intercommunicating pore and diaphragm seal；Described protective cover is directly filled on intercommunicating pore top, and its upper surface is formed with groove；Described metal funnel is in nearly hemispherical, and diameter is more than the diameter of the intercommunicating pore, and funnel bottom is a non-porous plane, then regular on sphere to be dispersed with many apertures.After the structure enables, electrolyte can be injected toward inside battery by intercommunicating pore, because fluid-filling structure lower end is provided with metal funnel, it can prevent broken diaphragm seal from falling into battery, battery safety is ensure that, can be by carrying out discharge and recharge to battery after having noted electrolyte battery is again sealed off, recover the performance of battery, so as to extend the service life of battery.
Description
Technical field
Waste lithium cell reutilization technology field is the utility model is related to, is recycled more particularly, to waste lithium cell fluid infusion
Field.
Background technology
With the fast development of new-energy automobile, as the lithium ion battery of new-energy automobile core, that is, welcome rare
The market opportunity, but bring a little hidden danger again simultaneously, it is just no longer suitable when these batteries can only be filled to original capacitance 80%
Close and continue to use on electric automobile, how to tackle market after electric automobile, rationally recovery and utilize these electrokinetic cells, will be into
For the exhibition direction of enterprise.
Research is found, is supplemented by carrying out electrolyte to the battery of decay, it is possible to increase the capacity of battery and its circulation
Life-span.But top cover fluid-filling structure used at present is through the liquid injection hole of cover plate, note after liquid generally by sealing steel ball or envelope
The mode of mouthful weldering seals to it, and being unfavorable for the later stage reopens liquid injection hole, carries out fluid infusion again.
Utility model content
The purpose of this utility model is the electrolyte replenishing structure again for providing battery cap, it is intended to solves existing fluid-filling structure sealing
After be unfavorable for reopening progress fluid infusion problem again, the recycling longevity of battery can be extended by carrying out fluid infusion by the structure
Life.
To achieve the above object, the utility model employs following technical scheme：
A kind of quadrate lithium battery top cover electrolyte replenishing structure, including battery cover board body and liquid injection hole on the cover board is opened up, institute
The intercommunicating pore for offering on cover board body and being connected with inside battery is stated, intercommunicating pore bottom is provided with funnel, and intercommunicating pore is connected with funnel
A termination be provided with blocking the diaphragm seal of intercommunicating pore.
A kind of quadrate lithium battery top cover electrolyte replenishing structure, another port that described intercommunicating pore is provided with diaphragm seal are provided with protection
Lid, lid are located on port.
A kind of quadrate lithium battery top cover electrolyte replenishing structure, described intercommunicating pore by aperture it is different up and down two form, top
Aperture is more than bottom aperture.
A kind of quadrate lithium battery top cover electrolyte replenishing structure, described funnel are metal funnel, and metal funnel is in nearly hemispherical, bottom
Portion is a non-porous plane, then regular on sphere to be dispersed with many apertures.
A kind of quadrate lithium battery top cover electrolyte replenishing structure, the diaphragm seal are a kind of circular metal paillon foils.
Compared with prior art, the electrolyte replenishing structure again of battery cap provided by the utility model, can rise before not enabled
Acted on to being fully sealed；Fluid infusion again can very easily be carried out by the electrolyte replenishing structure after cell decay, manually removed anti-
Shield, when noting electrolyte toward electrolyte replenishing structure, caused pressure destroys rupture pressure disc, and broken rupture pressure disc drops in metal funnel,
Hinder foreign matter to fall into battery and ensure that the security performance of battery, after electrolyte has been noted, then by sealing steel ball or sealing
The mode of weldering completes the sealing of battery.Lithium battery fluid infusion again so easily can be simply realized, extends its service life.
Brief description of the drawings
Accompanying drawing 1 is the sectional view of cover plate of the present utility model.
Wherein：
1st, cover plate, 2, liquid injection hole, 3, metal funnel, 4, protective cover, 5, diaphragm seal, 6, intercommunicating pore.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
Battery cap as depicted electrolyte replenishing structure, including cover plate 1, liquid injection hole 2, protective cover 4, metal funnel 3 and note again
Liquid structure.Described fluid-filling structure is located on shown cover plate 1, and fluid-filling structure is made up of intercommunicating pore 6 and diaphragm seal 5, and intercommunicating pore 6 passes through
Cover plate 1 is worn, described intercommunicating pore 6 is made up of the different two parts up and down in aperture, and top aperture is more than bottom aperture, in intercommunicating pore
Joining place, which is provided with, to be used to close required diaphragm seal 5, and described diaphragm seal 5 is a kind of circular metal paillon foil, and its diameter is with connecting
The lower diameter of hole 6 is identical, can ensure the sealing of battery in itself before the electrolyte replenishing structure is not actuated；Described fluid-filling structure lower end
Provided with the metal funnel 3 immediately below the intercommunicating pore of position, metal funnel 3 is in nearly hemispherical, and diameter is more than the diameter of the intercommunicating pore 6,
Funnel bottom is a non-porous plane, then regular on sphere to be dispersed with many apertures so that electrolyte pass through aperture
Flow to inside battery, described protective cover 4 is directly filled on the top of intercommunicating pore 6, and its upper surface is played before not enabled formed with groove
The little particle foreign matter such as dust is hindered to fall into battery, so that it is guaranteed that with the security performance of inside battery after the structure, described note
Fluid apertures 2 is the liquid injection hole used in normal fluid injection in cell production process.
Specifically, inject the electrolyte into inside battery by liquid injection hole 2 in production, fluid injection terminate after by seal steel ball,
Seal welding is sealed.When cell decay to be no longer appropriate for continue in the capacity used on electric automobile when, manually remove fluid infusion
Protective cover 4 in structure, by intercommunicating pore 6 toward electrolyte is injected in battery, during electrolyte is injected, it can produce enough
Big pressure destroys diaphragm seal 5, and broken diaphragm seal drops in metal funnel 3 and electrolyte can be by the porose sphere of funnel
It flow to inside battery and completes fluid injection, described metal funnel 3 can prevent broken diaphragm seal 5 from dropping into inside battery, from
And the security performance of battery can be ensured, after electrolyte has been noted, then intercommunicating pore 6 is entered by way of sealing steel ball or Seal welding
Row sealing, the sealing of complete battery pair, battery make the battery extensive by discharge and recharge again again in the case of sufficient electrolyte
Original performance is arrived again.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
