Object cathode.Therefore lithium ion battery needs to carry out first charge-discharge activates to it, i.e. progress formation process.In formation process, electricity
Solution liquid is chemically reacted in negative terminal surface, forms one layer of solid electrolyte film（SEI film）, SEI film can prevent electrolyte
Solvent molecule enters cathode, and negative pole structure is caused to destroy.In addition, if will cause analysis lithium and dead with the presence of gas inside battery core
Area influences later period battery core capacity.Therefore, the quality of formation effect directly determines the performance superiority and inferiority of lithium ion battery.In consideration of it,
It is necessary to provide a kind of soft bag lithium ionic cell formation devices, to improve and improve the formation effect of soft bag lithium ionic cell, into
And improve the safety and service life of battery.
Utility model content
The purpose of this utility model is that：For the deficiency of current forming technology, a kind of soft bag lithium ionic cell is provided
At device, formation effect can be further increased and be improved, improve the consistency of performance of lithium ion battery, safety and uses the longevity
Life.
In order to reach above-mentioned technical purpose, the utility model adopts the following technical solution：
A kind of fixed device of soft bag lithium ionic cell chemical conversion, it is described including multiple for clamping the clamping plates of lithium ion battery
Clamping plate is fixed between two vertically disposed fixed columns by fixed link, positioned at clamping plate both ends respectively in parallel be equipped with push plate and
The threaded one end of support plate, the push plate and drive rod connects, and support plate is installed in fixed link；It hangs down at the both ends of the drive rod
Direct puncture is located in fixed column, and the end of drive rod is connected to motor, and motor drives drive rod rotation, makes push plate to support plate direction
It moves and exerts a force to clamping plate.
Further scheme, the clamping plate is equipped with the pressure sensor for detecting lithium ion battery surface pressure, described
The output end of pressure sensor is connect with controller, and the output end of the controller is connected to motor.
Further scheme, the clamping plate is movably set in fixed link, and is fixed by fixed pin, makes adjacent cleats
Between size matched with the size of lithium ion battery.To be suitable for the lithium ion battery of different outer dimension sizes.
Further scheme, there are two the drive rods, to be arranged in parallel.
Lithium ion battery to be changed is placed between clamping plate and grips by the utility model, then by lithium ion
Tab part and the formation cabinet of battery link together, and starting formation cabinet is melted into.The chemical conversion incipient stage passes through motor and drives
Drive rod rotation keeps push plate mobile to support plate direction and applies an initial pressure P1 to clamping plate, and pressure sensor is real
When monitoring formation process in lithium ion battery surface pressure change, and be fed back to controller, controller is big according to pressure
The small revolving speed to adjust motor, and then adjust push plate and be applied to the pressure on clamping plate.With chemical conversion the time increase, Soft Roll lithium from
The gas production of sub- battery gradually increases, and the pressure of lithium ion battery surface is also gradually increased, then increase accordingly external force.The pressure of increase
The hydrogen fluoride gas generated inside soft bag lithium ionic cell can be more effectively more fully discharged in airbag by power, therefore Soft Roll lithium
The gas of ion battery internal residual can be reduced greatly, and battery core analysis lithium and dead zone phenomenon can be controlled preferably
System, and then can effectively increase the capacity, battery core consistency of performance and battery core service life of battery core.Finally, lithium ion battery produces gas base
This terminates, i.e. when the pressure of pressure sensor detection is constant, then stops motor work, the pressure dimension for being applied to push plate on clamping plate
It holds in a stability number.
So the fixation device of the utility model applies pressure to lithium ion battery by clamping plate, and with lithium ion battery
The variation of gas production and apply different power, so as to reduce hydrogen fluoride gas inside soft bag lithium ionic cell to the greatest extent
Residual quantity, more effectively control battery core analysis lithium and dead zone phenomenon, i.e. the utility model can effectively improve and improve battery core and holds
Amount improves consistency, safety and the service life of soft bag lithium ionic cell performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1- motor, 2- fixed column, 3- push plate, 4- drive rod, 5- fixed link, 6- clamping plate, 7- support plate, 8- pressure

Specific embodiment
Below in conjunction with the attached drawing in the utility model, the technical solution in the utility model is carried out clearly and completely
Description, it is clear that described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Base
In the embodiments of the present invention, institute obtained by those of ordinary skill in the art without making creative efforts
There are other embodiments, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of soft bag lithium ionic cell is melted into fixed device, including multiple for clamping lithium ion battery
Clamping plate 6, the clamping plate 6 are fixed between two vertically disposed fixed columns 2 by fixed link 5, are distinguished positioned at the both ends of clamping plate 6
It is equipped with push plate 3 and support plate 7 in parallel, the push plate 3 is connect with the threaded one end of drive rod 4, and support plate 7 is installed in fixed link 5
On；The both ends of the drive rod 4 are vertically threaded through in fixed column 2, and the end of drive rod 4 is connect with motor 1, and motor 1, which drives, to be passed
Lever 4 rotates, and keeps push plate 3 mobile to 7 direction of support plate and exerts a force to clamping plate 6.
Further scheme, the clamping plate 6 are equipped with the pressure sensor 8 for detecting lithium ion battery surface pressure, institute
