AI Technical Summary
Technical Problem
In existing battery technologies, improperly designed pressure relief mechanisms in cylindrical battery cells can easily lead to heat spread and explosion risks, and also result in low space utilization.
Method used
A pressure relief mechanism is provided on the cylindrical side of the battery cell, and the battery cell is divided into first and second regions by an isolation component. The first region is used to accommodate part of the battery cell for positioning and fixation. When the pressure relief mechanism is actuated, the discharged material enters the collection chamber to avoid contact with the electrical cavity.
Benefits of technology
It improves battery stability and safety, reduces the risk of explosion, and increases space utilization.
