A dual-membrane battery vent combines normal pressure equalization and emergency gas release in one assembly to cut parts, weight, and maintenance.

Braze joints melt at set temperatures to open large vent areas in prismatic cells, releasing hot gases and particles during thermal runaway.

A ramp-fastened closure cap enables battery housing emergency degassing at lower differential pressure with more precise vent switching.

A mesh-covered vent with a duct adsorption member keeps battery pack gas relief paths clear while trapping particles and limiting flame exposure.

A notched anti-explosion valve enlarges the opening region relative to battery capacity to vent internal pressure faster and improve safety.

Uses vent-gas pressure to break an electrical line, enabling reliable battery cell degassing detection without temperature sensing.

Offsetting the fire extinguishing pipe from battery cell vent centers helps it survive gas discharge and maintain suppression during module fire events.

Direct cell stacking with center, side, and end frames raises battery pack energy density while maintaining compression and mechanical stability.
