Cell Sealing Materials TRIZ Cases

A stepped electrolyte injection pellet improves insertion and forms a double seal against the battery housing to prevent leakage.

A dented lead film creates a closed gas path through the seal, relieving cell pressure while limiting moisture ingress and preserving airtightness.

A metal seal plate with a ring-shaped thermoplastic resin valve limits creep and vapor permeation while opening under heat to release pressure.

Matched protrusions and grooves lock the terminal sealing member to the wall, limiting sliding and preventing seal detachment under pressure.

A thin acid-modified polypropylene adhesive layer boosts battery lead sealing strength while preserving heat stability and electrolyte durability.

A clip-like venting member on the pouch-cell seal opens under gas pressure to prevent swelling and explosion without complex vent pipes.

Riveting the pole through the cover plate replaces welding to simplify assembly, improve sealing, and enable denser cylindrical battery grouping.

A hinged electrode seal with inert gas injection enables continuous electrode replacement while limiting heat loss and process disruption.

An insulating member seals the gap between the cap plate and terminal plate to prevent welding-related short circuits in secondary batteries.

A layered battery case uses a heat-resistant gas barrier and sealant opening to block gas leakage while improving cooling in solid-state cells.

A laminated battery case uses a heat-resistant gas barrier layer and sidewall opening to limit gas leakage while improving heat dissipation.

A grooved terminal and spaced adapter seal reduce heat transfer from the external joint, protecting battery cell components and connection stability.

Grooved cap and insulating member nesting frees battery interior space, allowing taller cells and higher capacity without enlarging the casing.

A bridged dual-cup pouch case prevents bat ear formation during folding and sealing, improving size accuracy, energy density, and module assembly.

A lower-melting vent resin in an inclined seal directs failure gas away from the electrode lead to reduce thermal propagation risk.

A segmented current collector places the fuse region outside the terminal area, enabling wider tabs for higher output and easier battery pack assembly.

A guide frame holds a tube through the pouch to enable electrolyte filling and gas discharge without weakening pouch sealing.

An asymmetric pole profile in a battery top cover balances easy assembly with stronger torsion and tensile resistance for stable operation.

An elongated pole profile with a 2≤L1/L2≤3 ratio improves torsion and tensile resistance in battery top cover assemblies.

An integrated battery sealing member adds a force-applying portion to prevent leakage while enabling simpler secondary injection.

A compact end cover assembly lowers electrode terminal height to free more cell volume, improving secondary battery capacity and energy density.

A protruding sealing-member adapter creates axial and radial spacing that slows heat transfer from the external joint to the battery cell terminal.

An extended pouch sealing portion restrains electrode assembly movement under impact, reducing short-circuit risk in secondary batteries.

An extended pouch sealing portion and insulating tape limit electrode assembly movement under impact, reducing short-circuit risk.

A soluble gasket dissolves in bodily fluids to trigger internal discharge in a button battery, reducing harmful external current after ingestion.

A rivet vent recess fractures under rising cell pressure to release gas while a sealing member maintains electrolyte port sealing.

Polymer anchors formed through tab holes reinforce pouch-cell seals, raising pressure tolerance without sacrificing electrical conductivity.

A curved pouch-cell edge and outward-bonded seal reduce adhesive stack-up, shrinking battery size while maintaining leak protection.

A thinner adhesive layer paired with a thicker insulation member improves battery end cap retention, insulation, and assembly compactness.

A protruding outlet and blocking channel extend the electrolyte path to limit reverse flow, reduce leakage, and improve battery cell filling.

A raised joint protrusion on the sealing cover clears the welding seam, improving busbar welding yield and connection stability.
