Cell Sealing Materials TRIZ Cases

Communication paths vent residual electrolyte during swaging, helping the sealing member fully seat and preventing inadequate battery sealing.

A recessed pouch-cell sealing structure contains gas, delays venting, and prevents electrical corrosion while improving dimensional stability.

A same-face terminal layout and selective Parylene coating improve battery pack resistance to moisture and liquid infiltration.

A protrusion-and-groove pouch bag opens for degassing and recloses afterward, avoiding laminate scrap and lowering battery manufacturing waste.

An uncured adhesive lets the insulating layer move during aluminum case stamping, preventing film damage, trapping metal dust, and reducing short circuits.

A stepped copper-aluminum pole improves current collector welding and bonding strength while reducing material cost, corrosion risk, and detachment.

Dual-seal busbar assemblies isolate high-voltage battery array connections from cooling fluid while simplifying pack assembly and tolerance handling.

Interlocking recessed shell and cover plate features stop welding shift, improve housing precision, and free more cell volume.

An embedded groove and locking block join copper and aluminum pole parts to improve tensile strength, shock resistance, and connection reliability.

A stepped composite battery terminal improves current collector welding while reducing metal layer thickness, diameter, and cost.

A terrace lead structure, insulating tape, and a gas pocket let thicker pouch cells improve pressure resistance and heat dissipation.

A self-restoring adhesive vent opens under pouch pressure, then reseals to stop ongoing electrolyte and gas discharge.

A flanged gasket between the terminal and cap plate improves sealing and terminal stability while preserving internal battery space.

A notch-filled tab seal replaces through-hole sealing to cut space use, simplify assembly, and improve electrochemical cell reliability.

Nested inner and outer insulators stabilize terminal connection in a battery case assembly while reducing short-circuit risk during charge and discharge.

Direct resin molding around a metal terminal removes extra insulation parts while maintaining hermetic sealing against electrolyte and moisture.

A hydrophobic inorganic filler in the adhesive layer limits sealant flow under heat and pressure, preserving insulation and preventing shorts.

A recessed post assembly applies direct compression to form double sealing, cutting top cover complexity, weight, and space use.

By moving the bus-bar weld away from the pole edge, this battery pack case reduces seal melting and sealing failure at terminal joints.

A receiving groove captures weld overflow at the electrode pole-terminal joint, keeping the battery top cover flat and even.

A color-changing terminal film reveals hydrogen sulfide in sulfide solid-state batteries early while helping preserve terminal sealing strength.

A threaded seal and sealing ring replace weld-sealed injection holes, reducing electrolyte leakage risk, process complexity, and cost.

A flanged gasket in the cap assembly strengthens electrode terminal retention under vibration and shock while preserving battery internal space.

Directly joining current-collector protrusions to busbars removes extra weld points, lowering resistance, heat, and voltage error in battery modules.

A grooved housing wall nests the terminal seal structure to save cell space while maintaining terminal mounting strength, insulation, and sealing.

A spaced pole terminal and bus-bar connection keeps welding heat away from the top cover seal, reducing melt risk while preserving air tightness.

Ceramic support and limiting rings replace heat-sensitive PPS parts to keep battery cover plate terminals insulated and sealed above 250°C.
