Cell Lids/Covers TRIZ Cases

A segmented insulating member creates a direct gas path to the pressure relief mechanism, speeding side venting during thermal runaway.

An insulator surrounds the battery terminal head to prevent bus bar contact while preserving electrical access and liquid-tight sealing.

A pressure-responsive venting sheet and support cap discharge internal battery gas while blocking external flame or gas entry.

Directly joining the box side wall to the mating side surface removes flanges, saving battery space while maintaining strength and hermeticity.

A straight shared cooling path between upper and lower cell stacks reduces refrigerant pressure drop while improving temperature uniformity and space use.

Asymmetric main and auxiliary notch geometry improves vibration resistance while enabling stable, prompt battery gas discharge under pressure.

A grooved bracket nests and binds the electrical connecting member to save module space, protect it from damage, and raise cell density.

A thickened lower-case boundary and inclined side wall spread impact loads and block rainwater ingress in storm-exposed battery packs.

A rivet with protrusions and flanges improves gasket contact in the cap assembly, limiting electrolyte and gas leakage despite tolerances.

Opposed protrusion and recess patterns help thin battery module covers resist twisting during molding while preserving flatness and mechanical strength.

A metal bottom cover with an integrated exhaust pipe protects the explosion-proof valve from assembly damage and keeps gas discharge smooth.

Outward venting redirects gas, flame, and heat away from adjacent battery modules to limit thermal runaway propagation and improve pack safety.

Multiple vent plates linked to one elevating member open together at set pressure, speeding gas release and improving battery safety.

Offset adjacent battery cell center lines to disperse expansion forces, reduce reserved space, and improve structural stability and energy density.

Elastic displacement plates simplify battery module fastening while maintaining vibration stability, shock resistance, and moisture protection.

Integrating the vent valve into the battery pack top cover cuts parts and assembly steps while improving sealing and pressure relief reliability.

A two-part current collector improves molten pool fusion by matching the weld-side melting point to the electrode lead-out portion.

An expandable barrier and spring-loaded seal block and redirect battery vent byproducts through pack gaps to limit cascading thermal events.
