AI Technical Summary
Technical Problem
The injection opening on the top of a battery cell impedes electrolyte infiltration due to the presence of electrode plates and tabs, leading to low injection efficiency.
Method used
The design includes an injection opening with a central axis positioned to minimize interference from the laminated cell, allowing electrolyte to bypass and directly flow into an injection space, and a sealing piece to ensure sealing after injection.
Benefits of technology
Improves electrolyte injection efficiency and infiltration into electrode plates, enhancing the overall electrolyte distribution within the battery.
