Leaked electrolyte is routed through a support beam discharge cavity to prevent insulation failure and liquid buildup in the battery.

Placing the pressure relief mechanism between battery end-cover terminals frees space for a larger vent and smoother emission discharge.

A top pressure relief valve and lower breathable membrane use debris deposition to block air inflow and suppress battery heat after gas discharge.

A vent-mounted rotating member uses internal gas flow to cut discharged gas heat while relieving battery pressure during abnormal conditions.

Protruding terminal covers and vented connection structures block hot ejecta and isolate cell venting to limit thermal runaway spread.

Mechanical interlocks, adhesive, and elastomer seals position battery cells accurately while blocking potting leakage into vent channels.

Integrated heat exchange beams cool battery cells while reinforcing the box frame, freeing bottom space to improve pack energy density.

Integrally formed limiting stages let battery terminals rivet to the casing, simplifying assembly while preventing detachment during use.

An inert carrier gas enables continuous, quantitative monitoring of pouch-cell gas evolution during cycling, improving baseline stability and gas identification.

A supported pressure relief vent opens at a fixed angle to direct hot battery emissions into a thermal management component for cooling.

A vented shielding member buffers electrolyte impact and evens chamber pressure to prevent false explosion-proof sheet triggering after drops.

A venting guide wall around the battery cap plate vent redirects hot jets away from neighboring cells to limit secondary thermal events.

A meltable insulator at the electrode post forms a vent path under heat, relieving battery pressure while avoiding separate valves and laser drilling.

Corner vent holes disperse thermal runaway gas and flame from a battery module, reducing damage risk to adjacent modules.

Pre-assembled stacked cell units with coupling supports simplify battery pack handling, cut structural bulk, and protect cells during installation.

Open-face electrolyte filling speeds battery cell assembly, improves electrode wetting, and removes the need for fill ports and multiple stations.

Tubular vent-frame passages redirect gas, heat, and flames away from adjacent modules to limit thermal runaway transfer in battery packs.

Integrated bus bar housing adds cooling, temperature sensing, and pressure sensing to battery modules without sacrificing energy density.

A polyolefin-based gas adsorption film captures cell gas while resisting electrolyte reaction, limiting pouch swelling and performance loss.

A ventilation pipe and gas extractor route thermal runaway gases out of battery packs quickly, preventing cabin buildup and pollution.

Separated insulating members and a metal valve support improve end cover strength, thickness uniformity, airflow, and thermal runaway protection.

A resin protrusion anchored by nanocolumn roughening keeps electrode debris from blocking the safety valve and preserves gas release.

An extendable upper-case section redirects battery gases across limited excess space to prevent hot-debris short circuits.

A laser-roughened valve area anchors a resin protrusion that keeps broken electrode pieces from blocking gas release in metal battery cases.

A gas-permeable, liquid-blocking membrane balances battery housing pressure while a separate valve handles emergency overpressure release.

Heat-resistant barriers and compartment vents contain thermal runaway by isolating battery cells and discharging hot gas outside the module.

A cap plate venting guide wall redirects hot gas jets upward, relieving cell pressure while limiting thermal spread to neighboring cells.

Side vent openings route hot gases into inter-battery channels, lowering thermal runaway risk while keeping the storage layout compact.

A one-way guiding part routes thermal runaway emissions into an exhaust chamber while blocking backflow that can spread smoke between battery cells.

Rupturable vent covers on a busbar holder release cell gases while blocking flame spread and thermal damage between adjacent battery cells.

Melting dual fuse portions break battery short circuits while an exhaust path vents vapor and molten metal to limit plasma and fire risk.

A venting frame and horizontal pack-cover passage expel hot battery gases outside the pack while delaying cell-to-cell heat transfer.

Heat-resistant vent and support structures isolate adjacent battery cells while preserving gas discharge paths to limit thermal runaway spread.

Non-conductive coolant compartments and an air gap vent path limit cell-to-cell heat transfer and vent byproducts during battery thermal events.

Integrated flange vents and mounting holes let stacked battery modules fix and vent together, cutting inter-module gaps and improving energy density.

Engaging features between the upper-part case and cell case limit drop-induced mispositioning and prevent contact with the control board.

A frame with intermediate and top trays secures battery cells with minimal force, reducing loose-cell hazards and assembly damage.

A threshold-open valve lets fire-fighting medium enter a sealed battery box, relieving pressure and cooling cells during thermal runaway.

An edge-running exhaust groove in the bottom support plate vents thermal runaway gas through the shell gap to reduce battery explosion risk.

Weaker venting portions rupture before sealed edges, directing battery gas release while preserving sealing and reducing thermal runaway spread.
