Liquid injection encapsulation
The electrolyte is known as the "blood" of the lithium ion battery to conduct the positive and negative electrodes of the battery, which has a great impact on the working temperature, cycle efficiency, safety performance and rate performance of the lithium ion battery.
Process flow
1. The injection cup seals the battery core;
2. Through the injection port, the core is evacuated to a certain level to drain the air in the core and reserve the electrolyte space.
3. the electrolyte into the injection cup;
4. through the injection port of the electrolyte with a certain pressure into the core;
5. reasonable configuration 2,4 step cycle times, optimize the positive pressure and negative pressure value and time
Purpose
A certain amount of electrolyte is injected into the core from the injection port within a certain period of time.
Primary control point
Since the injection amount of the electrolytic wave is much larger than the free void volume of the shell, the injection velocity of the electric core will appear from fast to slow, which ultimately depends on the absorption rate of the positive and negative electrodes to the electrolyte.
Technical Difficulties
The width of the electrode plate (the height of the cell) and the gap between the cathode and anode plate and the isolation membrane will affect the injection speed.
In the case of the core material is determined, the injection efficiency can be improved by reducing and increasing the pressure difference to ensure that the electrolyte completely enters the core.
