Small-Sized Cells Cases/Jackets TRIZ Cases

Composite barriers with metallic reinforcing ribs resolve the contradiction between electrical insulation and mechanical strength in high-power battery modules.

Dual sealing segments prevent separator contraction from causing electrode short circuits without increasing manufacturing complexity.

Segmented insulation tape with varied widths adheres to sealing portions and terrace ends, countering spring back near short circuit check holes.

Integrates anti-rotation grooves into the cap plate to prevent terminal plate rotation and deformation during battery assembly.

Stepped terminal pin portions engage pre-formed rivet grooves in the cap plate, securing dissimilar metal connections without welding.

A vehicle battery case uses a guide partition wall to direct cooling air along a zigzag path across the module surface.

A glass seal element applies pressure through a reinforcement ring to create a hermetic feedthrough in thin metal housings.

Terminal cover part includes a regulating portion that contacts the battery upper surface to limit closing movement.

Notches and an insulating sheet on the top cover minimize wire-like metal debris generation, preventing short circuits in the electrode assembly.

Segmented carriers with mechanical interlocking replace epoxy assembly, eliminating contamination risks and enabling rapid repair of damaged cells.

Attenuates electromagnetic emissions by embedding damping elements within the housing, eliminating bulky external filters and reducing overall device volume.

A secondary battery plate terminal integrates with a cap plate featuring an upward protruding stepped portion to secure the connection.
