Abstract
The present invention relates to a kind of method improving battery liquid-filling sealing, it is before battery liquid-filling, one cylinder-like body with bonding plane is put into inside battery container, and make this cylinder-like body be close to the inwall of battery container mutually bonding with the inwall of battery container, then make filling head stretch into battery top by this cylinder-like body and carry out fluid injection.Present invention process is simple, does not increase too much cost, does not the most increase manufacturing process, simple and easy to do, can promote the fluid injection sealing effectiveness of battery, reduces the remaining electro-hydraulic amount of inner walls.
Description
Technical field
The invention belongs to lithium ion battery liquid injection technical field, be specifically related to a kind of side improving battery liquid-filling sealing
Method.
Background technology
The fluid injection of current battery has two ways, fluid injection mode one to be to seal with sealing gasket by battery case end face, fluid injection
Mode two is to seal with O by internal surface of battery shell, and both tradition fluid injection sealing means all have a certain degree of harm, ginseng
As shown in Figure 1, (in Fig. 1,1 is battery cover, and 2 is cell sealing to have portion of residual electrolyte 4 inside battery nickel plating housing 3
Circle).The most domestic be used mostly after plate battery case, coating is the finest and close, easily forms crackle after slot rolling, can remain more electrolysis
Liquid.During the continuous evacuation of fluid injection, remaining electrolyte is attached to inner walls and crystallizes, and seals it after fluid injection
Front inside battery meeting entering part air, this partial air can promote the electrolyte of crystallization to hydrolyze, discharges poisonous and have
The Fluohydric acid. of severe corrosive.The Fluohydric acid. discharged can occur strong chemical reaction with flash plating box hat part and sealing ring,
So that being no longer in close contact between battery cover and housing, causing battery that leakage in various degree occurs, once electrolyte oozes out,
To be all security threat to battery bag and overall use equipment.Therefore battery liquid-filling encapsulating method is solved, necessary.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem and a kind of method improving battery liquid-filling sealing is provided.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of method improving battery liquid-filling sealing, before battery liquid-filling, by a cylindrical shape with bonding plane
Body is put into inside battery container, and makes the bonding plane of this cylinder-like body point to the inwall of battery container and be close to the interior of battery container
Wall, then makes filling head stretch into battery top by this cylinder-like body and carries out fluid injection.
Present invention process is simple, does not increase too much cost, does not the most increase manufacturing process, simple and easy to do, the present invention
The fluid injection sealing effectiveness of battery can be promoted, reduce the remaining electro-hydraulic amount of inner walls.
Accompanying drawing explanation
Fig. 1 illustrates the schematic diagram leaving electrolyte under existing fluid injection mode on battery container；
Fig. 2 illustrates the fluid injection mode schematic diagram that the present invention can improve the method for battery liquid-filling sealing.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features and the advantage of the present invention are further described, but the present invention not office
It is limited to listed embodiment.
Shown in Figure 2, a kind of method improving battery liquid-filling sealing, before battery liquid-filling, by one with viscous
It is internal that the cylinder-like body 10 of junction puts into battery container 30, and makes the bonding plane of this cylinder-like body 10 point to the interior of battery container 30
Wall is also close to the inwall of battery container, then makes filling head stretch into battery top by this cylinder-like body and carries out fluid injection, in Fig. 2
Shown in arrow.
Described cylinder-like body 10 is spliced by the shoestring with bonding plane, and at splicing gap 11, docking forms one
Cylinder, as shown in Figure 1.
Fluid injection is carried out, now through vacuum owing to have employed after the cylinder-like body with bonding plane puts into battery container inside
After remaining electrolyte stick on cylinder-like body 10.After fluid injection operation completes, take out cylinder-like body 10, then battery cover joint
Without remaining electrolyte at the housing of contact, the chemical reaction i.e. will not being harmful to, also just without the generation of the phenomenon of leakage.
Wherein, implementing, the diameter of described cylinder-like body is slightly less than cell diameter, has the side of bonding plane or glue surface
To the housing of the battery of battery, and put into the inside of battery, this so can be made to be close to battery with the cylinder-like body of bonding plane
The inwall of housing, then makes filling head stretch into battery top by this cylinder-like body and carries out fluid injection.
Described cylinder-like body is made by adhesive tape and is formed, and at joint to connecting.
Present invention process is simple, does not increase too much cost, does not the most increase manufacturing process, simple and easy to do, the present invention
The fluid injection sealing effectiveness of battery can be promoted, reduce the remaining electro-hydraulic amount of inner walls.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
Claims (2)
1. the method improving battery liquid-filling sealing, it is characterised in that before battery liquid-filling, by one with bonding plane
Cylinder-like body put into inside battery container, and make this cylinder-like body be close to battery container inwall and with the inwall of battery container
Mutually bonding, then make filling head stretch into battery top by this cylinder-like body and carry out fluid injection.
The method improving battery liquid-filling sealing the most according to claim 1, it is characterised in that described cylinder-like body is by adhesive tape
Make and formed.
