AI Technical Summary
Technical Problem
Sealing assemblies in sealed batteries face challenges in achieving stable gas discharge performance while maintaining shock resistance, as conventional designs with thin engraved parts for gas discharge are prone to damage from external forces.
Method used
A sealing assembly with a projection having an inclined part and a thin section that fractures under internal pressure, utilizing tensile stress to ensure stable gas discharge and enhanced shock resistance.
Benefits of technology
The design achieves stable gas discharge performance and improved shock resistance by allowing the thin section of the inclined part to fracture under internal pressure, maintaining thickness for durability.
