(34.5~46h), and effective monitoring can not be realized to baking temperature.To sum up, currently used battery core drying process is generally existing
The problem that drying effect is undesirable and drying time is too long；How under the premise of guaranteeing battery battery core quality and safety, make to give birth to
Moisture content during production in lithium ion battery cell reaches related request and improves the efficiency of battery battery core baking as one
The problem of a urgent need to resolve.
Summary of the invention
In view of the deficiencies of the prior art, the technical issues of present invention intends to solve is to provide a kind of lithium ion battery cell
Toast drying process.The technique carries out battery core baking work and battery core by distinguishing alternate cycles in two identical inner lining bodies
Trolley, which goes out into tank, to work, and heats battery core with realizing uniform high-efficiency；And the temperature sensor by being pasted onto battery core car interior
Realize the real time monitoring to battery core baking temperature.The technique, which solves, vacuumizes, circulation time long with the dwell time in conventional method
Number is more, and high-temperature dry air may be with the aitiogenic problem of battery core.The technique can make battery core drying in production process
The required time greatly shortens.
The technical solution that the present invention solves the technical problem is to provide a kind of baking back tender of lithium ion battery cell
Skill, using baking production line, nitrogen heating system and the vacuum system of lithium ion battery cell；The production line includes in first
Liner body, preceding door and window, battery core trolley, left and right vehicle-transporting apparatus, the second inner lining body, side windows and doors, glove box and rear door and window；It is characterized in that
The technique the following steps are included:
1) the groups of battery core trolley for being loaded with battery core sequentially enters the first inner lining body under the promotion of left and right vehicle-transporting apparatus
In, when battery core trolley reaches specified number in the first inner lining body, the preceding door and window at the first inner lining body both ends and rear door and window are closed；It is logical
Side windows and doors and glove box the sticking temperature sensor in battery core trolley for crossing the first inner lining body, toast battery core in the first inner lining body
The real time monitoring of temperature；The first valve, the second valve, third valve, the 5th valve, being connect in nitrogen heating system with the first inner lining body
Six valves, the 8th valve and the 9th valve are closed；The tenth valve connecting in vacuum system with the first inner lining body and the 12nd valve are closed；
2) vacuum system works, and the tenth valve and the 12nd valve that vacuum system is connect with the first inner lining body are opened, by 30
Minute, the vacuum degree in the first inner lining body 1 reaches 5Pa~200Pa, and vacuum system stops working, vacuum system and the first liner
The tenth valve and the 12nd valve of body connection are closed；
3) nitrogen heating system works, the first valve that nitrogen heating system is connect with the first inner lining body, the second valve, third
Valve, the 5th valve, the 6th valve, the 8th valve and the 9th valve are opened；Liquid nitrogen successively pass through the first valve, vaporizer, pressure reducing valve, the second valve and
After heater, become hot nitrogen；Hot nitrogen enters the first inner lining body after third valve and the 5th valve, through nitrogen heating system,
So that the intracorporal temperature of the first liner maintains 80 DEG C~100 DEG C, battery core in the first inner lining body is evenly heated；It is warm after work
Degree declines and the nitrogen containing impurity passes through nitrogen heating system and flows out the first inner lining body；Again successively through the 6th valve, the 8th valve, slow
After rushing device, air pump blower and the 9th valve, heater heating is come back to；Battery core heats 1 under conditions of 80 DEG C~100 DEG C of temperature
Hour；The first valve, the second valve, third valve, the 5th valve, the 6th valve, the 8th valve and the 9th valve are successively closed after heating；Heat preservation
5 minutes, continue to handle in next step；
4) step 2) and step 3) are repeated twice, after battery core is cooling, by side windows and doors and glove box to the first inner lining body
The battery core of three positions samples and carries out water content test before, during and after interior；If the water content of battery core sample be 50ppm~
200ppm then reaches baking standard；If the water content of battery core sample is higher than 200ppm, not up to baking is required, and is repeated again
Step 2) and step 3) simultaneously carry out water content test, until reaching standard；After battery core reaches water content standard, by temperature sensor
It is removed from battery core trolley, the Roaster work of battery core terminates；Door and window is opened afterwards, by being located at the left and right fortune vehicle at the window position of back door
The battery core trolley for being loaded with battery core is sent to next station by device；
When carrying out battery core baking work, the second inner lining body is carrying out battery core trolley and is going out into liner (5) first inner lining bodies
The work of body；The baking of first inner lining body and the second inner lining body alternately battery core and go out into inner lining body work.
Compared with prior art, the beneficial effects of the invention are that:

Evaporation is more complete, and cured effect is preferable, and diaphragm can be effectively prevent to fail because temperature is excessively high.
(2) gas of the purity for 99.999% nitrogen as baking battery core is used, battery core high temperature in baking process is avoided
The problem of oxidation；And it can be by impurity such as the moisture being evaporated in nitrogen from inner lining body by heating and the cyclic process that vacuumizes
It is completely exhausted out.
(3) relative to the drying time of conventional drying process is long, disadvantage of drying effect difference, in the baking drying process singly
Total drying time of a intracorporal battery core of liner can control the water of the battery core sample by 5 hours or so, after the completion of baking process
Content reaches 50ppm~200ppm；Give full play to that automatic production line high production efficiency, manufacturing cycle be short, product quality weight
The high feature of renaturation.
(4) by distinguish in two identical inner lining bodies alternate cycles carry out battery core toast work and battery core trolley go out into
Tank work, heats battery core with realizing uniform high-efficiency.
(5) sticking temperature sensor in the battery core trolley in inner lining body is realized to battery core by side windows and doors and glove box
The real time monitoring of baking temperature；At the end of baking, the battery core after baking is sampled and is carried out aqueous by side windows and doors and glove box
Examination is measured, to determine the whole cured effect of this batch of battery core.
(6) admission line in nitrogen heating system and outlet pipe reach uniform according to hot nitrogen fluid in inner lining body
The mode of stream is arranged.
