Vent Arrangements TRIZ Cases

Capillary channels between battery cells and sleeves drive passive liquid cooling, improving heat extraction while simplifying pack structure.

A double-cover battery pack vents failure gas through a slit and mesh barrier while blocking flames and hot particles to limit module damage.

Side and center venting channels with barriers route high-temperature gas outside the pack to isolate adjacent modules and reduce propagation risk.

A roughened terminal notch lets a laminated battery casing tear at a set pressure more consistently without tight heat-seal accuracy.

Deformable inner and outer barriers vent battery gases while blocking flame rebound, heat transfer, and conductive particles between modules.

Multiple channels in the insulating member speed electrolyte filling and reduce separator blockage at the battery cover plate.

Protruding covers around terminal exposure holes block hot fragments and flames, helping isolate failing cells and stop chain ignition.

A heat-expanding member redirects pouch-cell outgassing to a designated region, limiting pressure, short circuits, and heat spread.

Multiple liquid channels in the insulating member speed electrolyte filling, improve distribution, and avoid blockage near the terminal assembly.

A narrowed vent outlet lets battery packs discharge electrolyte gas while limiting external air ingress, pressure buildup, and flame spread.

A supporting member restrains electrode assembly movement so the pressure relief path stays open and hot gases discharge quickly.

Inflated roll-bonded metal sheets create cooling channels that adapt to cell height variation, improving heat transfer and cooling uniformity.

Roll-bonded metal sheets integrate cooling and crash channels into battery pack housing, reducing parts, assembly burden, and manufacturing cost.

Roll-bonded metal sheets create battery module housing with integrated cooling and crash channels, reducing assembly effort and improving cell cooling.

Passageways in an electrode stack bracket route thermal runaway gas to a vent, relieving pressure while preserving cell support.

A tapered gas discharge path raises inlet-outlet pressure difference, allowing faster battery pack venting through the same disk area.

A dual sensing part monitors both cell terminals and vent gas, cutting thermal runaway detection delay without adding sensors to each battery cell.

A meltable thermal member transfers heat in normal use, then creates an insulation gap and drain path to limit thermal runaway spread.

Insulating vent sheets with sloped thin units relieve cell gas while blocking flames and hot solids that can trigger chain ignition.

An insulating vent sheet with patterned thin units relieves cell gas while blocking flames and hot solids that can trigger chain ignition.

Integrated confinement volumes, particle filters, and a heated support plate contain thermal runaway ejecta while keeping battery temperatures uniform.

A movable lid and gas-permeable membrane balance normal battery housing pressure while opening high-flow emergency degassing.

A shared relief chamber with staggered vent openings saves pack space, raises energy density, and reduces gas interference during thermal runaway.

Selective foaming adhesive stabilizes pouch cells, while meltable isolation structures open exhaust channels for thermal runaway smoke.

Insulating cooling oil directly surrounds cells and bus bars to improve high-rate cooling, extinguish vented flames, and prevent short circuits.

A side cover member and venting unit redirect flame and gas around electrode leads to limit short circuits and thermal runaway propagation.

Supporting patterns, gas rooms, and balancing passages contain battery-cell gas pockets to limit leakage, swelling damage, and cell breakage.

A mesh screen between the top cap and safety vent releases gas while blocking heated active material that can trigger chain combustion.
