Background technique
Battery formation refers to the process of to charging/discharging of secondary cell.Battery is battery primary charging to new production at changing
Process.It is important link to the service life of this battery, very strict to lithium hedge battery request, be normally divided into constant-current charge with
Constant-voltage charge two stages, should first adopt low current trickle charge make battery terminal voltage to final discharging voltage constant current is charged to battery again
End voltage reaches constant-voltage charge voltage, then changes constant-voltage charge until being full of.
Lithium ion battery can generate gas during the manufacturing, in the chemical conversion stage, this is that traditional method is all stayed
There is a large amount of airbag to fill these gases, then by puncturing airbag, takes gas therein away with the mode of negative pressure of vacuum, this
Sample is needed using a large amount of aluminum plastic film, and aluminum plastic film is expensive, how to reduce the dosage of aluminum plastic film, becomes one of industry
Common objective.
For example, patent name is the reality that a kind of lithium ion battery is evacuated formation device application No. is 201621010430.2
With new patent:, by compressing the spring of sucker tail portion, making band before battery core chemical conversion according to describing for the patent work principle
There is the sucker of syringe needle to be close to airbag, correspondingly the syringe needle on sucker can puncture an osculum on airbag.When battery core starts to be melted into
Afterwards, a large amount of gas of electrochemical reaction generation occurs for battery core, and when the gas of generation reaches a certain amount of, the air pressure in airbag is greater than
The pressure of spring, the Exhaust Open punctured on airbag, the gas in airbag enter in sucker.Gas passes through sucker gas outlet
The vacuum tube of connection is pumped in surge tank, is discharged after overanxious organic corrosion gas.A part is discharged to the gas in airbag
Afterwards, when the air pressure in airbag drops to less than spring pressure, exhaust outlet is plugged, and continues electrochemical reaction, is so recycled
Until all gas is discharged.Though the patent has certain help to the reduction of airbag, structure is complex, operability
Difficulty, and reacting is carried out under negative pressure of vacuum, and gas cannot export inside battery core in time, have to battery core performance improvement
Limit.
For another example application No. is 201710699446.1, patent name be a kind of soft package lithium battery battery core negative pressure of vacuum be melted into and
The patent of invention of the method for encapsulation: it is melted into before producing gas, just by via hole inside entire battery core, the sucker being connected with vacuum
A vacuum negative pressure condition is formed, the gas generated when being melted into battery core is newly formed to export inside battery core by negative pressure, largely
While reducing airbag, is conducive to the formation of SEI film, improves battery core quality.Ingenious use suction cup sealed vacuumizes, not only
It is cheap, it is easy to operate, and whole operation is very simple and convenient, without complicated device.
But existing lithium battery negative pressure formation device has the following deficiencies:
(1) traditional formation regime is pressurization seal, pressurised openings chemical conversion and vacuumizes chemical conversion.Traditional chemical conversion that vacuumizes exists
Pp pipe is encapsulated on soft-package battery air bag, encapsulation is limited to pp pipe outside diameter and internal diameter cannot be too big, and the qualification rate of encapsulation is low, pumping
Speed is slow, the complex process of encapsulation；
(2) sealing effect for vacuumizing formation regime is usually undesirable, and pumping effect is bad, and encapsulation has gas entrance often
Sealing area, the quality decline of lithium battery influence the service performance of battery；
(3) gas of vacuum evacuation device extraction includes some corrosive gas, if without processing direct emission, it will be to people
Body and environmental pollution.

Shape channel includes the air storage bag of multiple connections, and the air storage bag is equipped with end socket.
Further, the volume of several air storage bags is gradually reduced from inside to outside, the channel between the air storage bag
It becomes narrow gradually.
Further, the side of the air storage bag is equipped with several sawtooth.
Further, the mode of the end socket sealing is bonding or heat seal or clamping.
Further, the blow vent is connected with filtering tank by vacuum-pumping tube.
Compared with prior art, the utility model has the beneficial effects that
(1) side of soft bag lithium ionic cell is arranged to aluminum plastic film tubular conduit by the utility model, passes through tubular conduit
Carry out fluid injection, chemical conversion.More traditional airbag encapsulation pp pipe method and process is simple, and qualification rate is high, has saved production cost；
(2) aluminum plastic film tubular conduit is designed to several air storage bags by the soft bag lithium ionic cell of the utility model, can be with
By the gas relative separation in each air bag, the separation of gas is preferably realized, the fusion of gas when preventing from encapsulating improves battery
Performance；
(3) gas of the utility model discharges after filtering tank filters, and keeps the process for producing lithium battery more environmentally-friendly.
