Description
Technical field
Lithium electricity is prepared the invention belongs to lithium battery preparation technical field more particularly to a kind of battery core fixture and using the fixture
The method in pond.
Background technique
Currently, the common process of lithium battery preparation, using encapsulation-fluid injection-- two envelope of ageing-chemical conversion pumping, which exists
Following problems: 1. fluid injection low efficiency；2. electrolyte infiltration is slowly, digestion time is long；3. battery is needed by encapsulating twice, technique
It is relatively complicated；4. needing to extract the exhaust gas that battery core chemical conversion generates when two envelopes, it is easy to take battery core electrolyte inside out of in pumping process
To cause the pollution of battery.
Summary of the invention
The purpose of the present invention is to provide a kind of battery core fixture, which can make fluid injection improved efficiency.
The second object of the present invention is to provide a kind of method for preparing lithium battery using the battery core fixture, this method shortening
The digestion time of battery once completes encapsulation after chemical conversion, electrolyte is extracted pollution electricity when effectively preventing taking out exhaust gas
The problem of pond ontology.
To achieve the goals above, the present invention adopts the following technical scheme that:
A kind of battery core fixture, it is characterised in that: the fixture includes upper cover plate, lower cover plate and sealing ring, the lower cover plate upper end
Face is provided with groove, and the sealing ring is between upper cover plate and lower cover plate and is circumferentially positioned at the periphery of the groove, it is described on
Cover board is fixed on lower cover plate, and the upper cover plate upper and lower surface perforation is provided with liquid injection hole, and the liquid injection hole is opposite with the groove
Setting.
Further, the lower cover plate upper surface is provided with seal groove, and the seal groove is circumferentially positioned at the groove
Periphery, the sealing ring are placed in seal groove.
Further, the upper cover plate is fixed with the lower cover crab bolt.
A method of lithium battery being prepared using the battery core fixture, is included the following steps:
Step 1: battery core is placed in the battery core slot being arranged on aluminum plastic film, the battery core slot of aluminum plastic film is placed on the groove
It is interior, sealing ring is placed, the sealing ring is pressed on the aluminum plastic film on battery core slot periphery, upper cover plate is fixed on lower cover plate；
Step 2: directly injecting electrolyte in liquid injection hole in vacuum environment and being removed after battery core ageing and chemical conversion
Cover board and sealing ring, battery core is encapsulated in aluminum plastic film, obtains lithium battery.
Beneficial effects of the present invention:
Battery core fixture documented by the present invention, structure is simple, easy to use, in the technical process for preparing lithium battery, in vacuum
When lower fluid injection, the liquid injection hole fluid injection that can directly open up from fixture is mentioned compared to the flaring fluid injection in conventional batteries production technology
Fluid injection efficiency is risen.
The method that lithium battery is prepared documented by the present invention is saved since electrolyte is directly inside liquid injection hole injection fixture
When having gone ageing electrolyte from airbag to battery core inside stage for penetrating into, effectively improve electrolyte infiltrating time；Compared to normal
The lithium battery encapsulation of rule-- two envelope technique of fluid injection-ageing-chemical conversion, the present invention prepare in the method for lithium battery, directly put battery core
It sets in fixture, fluid injection can be completed without encapsulation, only need to once be encapsulated after chemical conversion, by cell package in aluminum plastic film；Envelope
For battery core due to the exhaust gas that extraction chemical conversion generates from liquid injection hole, it is existing that when encapsulation, not will cause battery electrolyte pollution before filling
As.
