Description
Technical field
The utility model relates to technical field of lithium batteries more particularly to a kind of novel negative pressure formation devices.
Background technique
Lithium ion battery is with its energy density height, and light-weight, long service life, self-discharge rate is low, and memory-less effect etc. is excellent
Point is widely used in mobile communication, notebook, the industries such as electric car.However, lithium ion battery be widely used to it
Energy density it is also proposed that requirement.Especially passenger car, to mileage travelled, more stringent requirements are proposed.
At present to energy density mainly from the selection of battery material, using the negative electrode material of high-energy density.Main selection
Gao Shouxiao's, the negative electrode material of high gram volume, and the shortcomings that this kind of material is that chemomotive force is bad, in chemical conversion since chemical conversion produces
Conductance causes, and the place for generating bubble can have SEI film and not formed, and will appear the feelings such as analysis lithium after partial volume so as to cause battery
Condition.This problem can be melted by negative pressure and be solved, that is, inside battery is allowed to be in negative pressure state, be melted into the gas meeting of generation
It is taken away in time.The compactness of pole piece and diaphragm can be kept preferably, be easy the problem of failing so as to improve chemical conversion.
Formation cabinet generally comprises connecting plate, cathode contact column, positive contact stud, negative port etc. at present, and usually 32
One pallet of battery, in chemical conversion, a puck battery pond shares a vacuum tube, very appearance have battery not and be condition of negative pressure into
Capable chemical conversion, and which is beyond recognition has negative pressure, which does not have negative pressure.Cause underproof chemical conversion battery that can not sieve
It elects.It is very poor so as to cause the battery consistency produced.Negative pressure chemical conversion also just cannot come into operation.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of novel negative pressure formation device, effects
Fruit is good.
The utility model proposes a kind of novel negative pressure formation device, including chemical conversion portion, chemical conversion portion include connecting plate, cathode
Contact stud, positive contact stud, negative port, cathode contact column, positive contact stud, negative port are installed on connecting plate；Change
It further include probe, contact induction device at portion, probe is located at the inside of negative port, and probe is connect with contact induction device, contact sense
Device is answered to be mounted on connecting plate.
It preferably, further include lifting unit, lifting unit and connecting plate are sequentially connected.
In the utility model, battery tray is allowed to enter formation cabinet, is equipped with a chemical conversion portion in the surface of each battery.
When being melted into, connecting plate is allowed to move downward, cathode contact column, positive contact stud can be positive and negative with battery respectively
Pole contact.External recharging apparatus is connect with cathode contact column, positive contact stud, starts to be melted into, and chemical conversion is exactly charging process, and
Battery activated process.
Negative port can be connected with battery liquid-filling hole, and external negative pressure device is by vacuum tube, negative port by inside battery
Air all take away, allow battery always to be in a state of negative pressure in formation process.One is increased among this negative port
A probe, this probe can reach inside battery by liquid injection hole.
If probe reaches inside battery, it is intact to show that external negative pressure device is connect with battery, at this moment, negative pressure device can be given
Battery increases negative pressure, and positive and negative anodes can be passed through electric current, and battery is normally melted into.If probe does not extend into inside battery, but touch electricity
On the shell of pond, at this moment it is bad to know that battery is connect with negative port for logical contact induction device, allows connecting plate to move upwards, corresponding battery
Stop chemical conversion.Cell voltage after chemical conversion is just not achieved in the cell voltage.
After puck battery chemical conversion terminates, which can be to after testing, detecting all electricity inside the pallet
The voltage in pond.Voltage qualification is then as pallet circulates down.Voltage is unqualified, is selected out, carries out secondary chemical conversion.So
Battery after ensuring that chemical conversion is entirely to pass through negative pressure chemical conversion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutual combination；Below with reference to the accompanying drawings it and in conjunction with the embodiments elaborates to the utility model.
Referring to Fig.1, the utility model proposes a kind of novel negative pressure formation device, including chemical conversion portion, chemical conversion portion includes connecting
Fishplate bar 1, cathode contact column 2, positive contact stud 3, negative port 4, probe 5, contact induction device 6, cathode contact column 2, anode connect
3, negative port 4 of striking the post is installed on connecting plate 1；Probe 5 is located at the inside of negative port 4, probe 5 and contact induction device 6
Connection, contact induction device are mounted on connecting plate.
In further embodiment, chemical conversion portion further includes lifting unit 7, and lifting unit 7 and connecting plate are sequentially connected.It rises
Dropping unit can be cylinder, drive connecting plate to go up and down using lifting unit.
Multiple chemical conversion portions can be set in formation cabinet, and battery tray is allowed to enter formation cabinet, are equipped in the surface of each battery
One chemical conversion portion.
When being melted into, connecting plate is allowed to move downward, cathode contact column, positive contact stud can be positive and negative with battery respectively
Pole contact.External recharging apparatus is connect with cathode contact column, positive contact stud, starts to be melted into, and chemical conversion is exactly charging process, and
Battery activated process.
Negative port can be connected with battery liquid-filling hole, and external negative pressure device is by vacuum tube, negative port by inside battery
Air all take away, allow battery always to be in a state of negative pressure in formation process.One is increased among this negative port
A probe, this probe can reach inside battery by liquid injection hole.
If probe reaches inside battery, it is intact to show that external negative pressure device is connect with battery, at this moment, negative pressure device can be given
Battery increases negative pressure, and positive and negative anodes can be passed through electric current, and battery is normally melted into.If probe does not extend into inside battery, but touch electricity
On the shell of pond, at this moment it is bad to know that battery is connect with negative port for logical contact induction device, allows connecting plate to move upwards, corresponding battery
Stop chemical conversion.Cell voltage after chemical conversion is just not achieved in the cell voltage.
After puck battery chemical conversion terminates, which can be to after testing, detecting all electricity inside the pallet
The voltage in pond.Voltage qualification is then as pallet circulates down.Voltage is unqualified, is selected out, carries out secondary chemical conversion.So
