AI Technical Summary
Technical Problem
In existing technologies, the rounded corner areas of batteries have material bending that causes large stress differences, increasing the risk of battery deformation and lithium plating. Furthermore, external impacts can easily cause lateral shear forces that can damage the cells, resulting in poor battery safety and reliability.
Method used
The battery cell is formed by stacking multiple wafers vertically and pressing them together for encapsulation. This reduces the rounded corner area, decreases stress differences, and improves the safety and reliability of the battery cell.
Benefits of technology
It reduces the failure rate of battery modules, extends their service life, and improves the space utilization and safety of battery modules.
