Description
Technical field
The utility model is related to polymer Li-ion battery production equipment technical field, and in particular to a kind of polymer battery
The filling head of electrolyte.
Background technology
In polymer Li-ion battery process of manufacture, the perfusion of electrolyte is entered in the environment of close drying
OK, needing electrolyte infiltration for a long time can just ensure the good contact of battery core and electrolyte.Current head for injecting electrolytic solution, typically
Direct reperfusion mode is selected, environment easily makes the presence of fine dusts inside electrolyte when being produced in itself due to electrolyte, secondly existed
Fluid injection link, its fluid injection environment is likely to result in electrolyte in dry air, causes the dust in air to be again introduced into electricity
In solution liquid, secondary pollution is caused.Further, since electrolyte infiltrates battery core for a long time, the aluminum plastic film of encapsulation electrolyte is also resulted in
With electrolyte contacts overlong time, cell package effect is influenceed.Influenceed by the above, eventually affected the product of battery
Quality.
Utility model content
The technical problem that the utility model is solved there is provided it is a kind of rational in infrastructure, easy to use, in electrolyte filling
Not by external dust pollution and the filling head of the polymer battery electrolyte for avoiding aluminum plastic film and electrolyte contacts overlong time.
Task of the present utility model is done in such a way that a kind of filling head of polymer battery electrolyte, including by poly- second
Upper lid and main body that alkene or polypropylene are made, upper lid are internally provided with the first cavity, and the first cavity surface is provided with internal thread, on
Cap upper surface is fixedly installed the gas pressure pipe and liquid injection pipe being connected with the first cavity respectively, and body top side surface is set
There is the external screw thread being engaged with internal thread, be internally provided with the second cavity being connected with the first cavity, the second cavity inside sets
Be equipped with it is identical with its cross section size circle electrolyte filtering net, electrolyte filtering net surface be coated with specification for 0.1 μm-
0.5 μm of filter paper, body lower surface is provided with the drain pipe road being connected with the second cavity, and drain pipe road end surface is provided with
Door, is provided with multiple and goes out material through hole on door.
It is further preferred that being provided with handle on the wall of upper lid side.
It is further preferred that winding is provided with unsintered tape between internal thread and external screw thread.
The utility model is rational in infrastructure and easy to use, it is ensured that what electrolyte was not influenceed in injection process by external dust
It also avoid electrolyte simultaneously to be contacted for a long time with plastic-aluminum packaging film, electrolyte filtering net and filter paper may filter that in injection process
The minute dusts that electrolyte exists in itself, meet the use demand of injecting electrolytic solution, and upper lid and main body are detachably connected, conveniently more
Change filter paper.

Specific embodiment
The technical solution of the utility model, a kind of filling head of polymer battery electrolyte, bag are described in detail with reference to accompanying drawing
The upper lid 1 and main body 2 being made up of polyethylene or polypropylene are included, upper lid 1 is internally provided with the first cavity 11, the surface of the first cavity 11
Internal thread 5 is provided with, the upper surface of upper lid 1 is fixedly installed the gas pressure pipe 4 and fluid injection being connected with the first cavity 11 respectively
Pipe 3, the top side surface of main body 2 is provided with the external screw thread 10 being engaged with internal thread 5, is internally provided with and is connected with the first cavity 11
The second logical cavity 8, the second cavity 8 is internally provided with the electrolyte filtering net 7 of circle identical with its cross section size, electrolyte
The upper surface of screen pack 7 is coated with the lower surface of 14 main body of filter paper 2 that specification is 0.1 μm -0.5 μm and is provided with and is connected with the second cavity 8
Logical drain pipe road 12, the end surface of drain pipe road 12 is provided with door 13, multiple is provided with door 13 and goes out material through hole 9, on
Handle 6 is provided with the side wall of lid 1.
During electrolyte filling, topping-up pump is connected with liquid injection pipe 3 and carries out conveying electrolyte, drain pipe road 12
Into packaging electric core plastic-aluminum packaging film fluid injection bag to battery core surface, while being by gas pressure pipe input pressure scope
The high pure nitrogen or argon gas of 0.3-1.0Mpa apply normal pressure to the inside of main body 2, electrolyte is efficiently passed through filter paper 14 and electricity
Solution liquid screen pack 7, electrolyte can avoid the secondary pollution of dust and filter the minute dusts that electrolyte exists in itself, while ensureing
