Radiation-crosslinked insulating adhesive film boosts battery cell cladding bond strength in harsh vehicle environments to prevent shorts and instability.

A gas pocket and optimized sealing-area-to-weight ratio help pouch batteries absorb impact, limit electrode shift, and prevent electrolyte leakage.

A glass frit and low-decomposition binder resin form a battery sealant layer that improves gas barrier performance and heat resistance.

Sealing grooves in a pouch cell collect molten colloid during hot pressing and open a gas discharge path during thermal events.

Projection portions on the tab film fill fold-bent cladding corners to suppress gaps and block inside-outside battery communication.

Critical temperature resistors on battery tabs short-circuit current through the case metal layer to prevent overheating and explosion in tight device spaces.

An elastic support member holds the lower insulating member in place, preventing downward shift while tolerating battery assembly gaps.

A connection pin inserted into a rivet stabilizes battery cell terminal joining, saves internal space, and simplifies cap assembly.

An offset sealing-plate recess locks the insulator in place, limiting displacement while preserving vent valve operation and battery integrity.

A three-layer cover integrates insulation into a button battery housing, enabling welded sealing without insulating film to reduce leakage and assembly complexity.

A temperature-deforming fastener unblocks a battery cover air hole during thermal runaway to vent gas, reduce pressure, and slow heat buildup.

A clad copper-aluminum terminal enables same-metal busbar welding, lowering resistance, heat buildup, gasket damage, and corrosion risk.

Male and female exterior plate joints replace welding in battery modules to avoid heat damage and dirt buildup around cells.

A tape or resin barrier seals the hole-edge metal boundary to block conductive liquid ingress and improve battery terminal corrosion resistance.

A curved cathode can and inclined terminal maintain gap-free contact after caulking, improving button cell welding strength and solderability.

Concave sealing plate features disperse vibration torque at the battery terminal joint, reducing damage to insulation and sealing parts.

Concave sealing plate features filled with insulation disperse vibration torque at the terminal, reducing junction damage and improving battery reliability.

A semiconductor safety element between the electrode lead and lead film absorbs heat and discharges an overheated pouch cell before fire or explosion.

A conductor with an intersecting fill hole simplifies top-cover welding, enables electrolyte replenishment, and lowers battery internal resistance.

An integrated feedthrough connector and insulator replace riveted battery posts to cut parts, simplify assembly, and free cavity space.

A fitted terminal protrusion and busbar hole shift laser welding away from the gasket, preserving seal integrity while maintaining joint strength.

Internal mounting channels and nested fasteners free battery case exterior space while keeping fixation stable and positionally flexible.

A lower-hardness grooved relief member cracks at pressure or heat thresholds to vent a battery cell while the end cover resists melting.

An annular groove and friction-welded sealing member close the battery cell injection hole with fewer defects, lower cleanliness demands, and less leakage risk.

A mating structure between the end cover and connecting member resists radial deformation, prevents electrolyte leakage, and improves battery cell sealing.

A resin layer compressed 20% to 30% in a housing groove seals battery pack gaps, blocking impurities and improving waterproofing.

Differential-melting vent layers keep the battery sealed in normal use, then route hot gases in one direction during thermal propagation.

An open-close pouch sealing structure vents trapped gas, then reseals the battery pouch to avoid aluminum laminate sheet waste.

A heat-responsive polymer layer on the electrode lead opens a vent in the pouch seal to release gas early and suppress thermal runaway.

Segmented adhesive layers cushion impact and limit electrode assembly displacement to reduce tearing and short-circuit risk in drops.

Direct tab welding to an integrated terminal base plate removes the connecting plate, cutting battery assembly steps, weight, and cost.

A position-limit boss controls seal compression during riveting, improving liquid injection hole sealing and reducing electrolyte leakage.

An integrated terminal base plate lets the tab be welded directly, removing connecting plates to cut welding time, weight, and cost.
