A transport device for lithium batteries in an aircraft, in particular in a hold, includes a container and a lid, lithium batteries being arranged in the container and the lid closing the container during transport of the lithium batteries. A shutoff valve neutralizes electrolyte released by the lithium batteries within the container or conveys the electrolyte to the outside.

A lead-acid battery (100) is provided with a lid (14). An external flow passage (530) communicating with a communication chamber (520) through a vent hole (321) and communicating with a discharge port (405) of a lid (14) is formed inside the lid (14). A compartment fence (452, 454) continuously extending over the entire width of the external flow passage (530) is formed in the external flow passage (530). A residual volume is larger than the volume of the communication chamber (520), the residual volume being obtained by subtracting, from the total volume of a plurality of external spaces (460, 462, 464) divided by the compartment fence (452, 454), the volume of the discharge-side external space (464) closest to the discharge port among the plurality of external spaces.

A battery pack includes a battery cell, a case having a housing space accommodating the battery cell, an exhaust tube connecting the housing space to outside of the case; a treatment agent container connected to the exhaust tube, and a supply controller between the exhaust tube and the treatment agent container.

Provided are a pouch-type secondary battery, a manufacturing method thereof, and a pouch-type secondary battery manufactured therefrom. More particularly, a pouch-type secondary battery having an electrode assembly built therein wherein the pouch has an opening and one surface or both surfaces of the opening are sealed by a gas separation membrane including a porous substrate and a composite layer including a polymer, in which silver particles or a silver salt is dispersed, laminated on one surface or both surfaces of the porous substrate, a manufacturing method thereof, and a pouch-type secondary battery manufactured therefrom are provided.

A battery unit includes a secondary battery, a first trap, and a second trap. The secondary battery includes a battery case provided with a gas vent valve, and an electrolyte solution enclosed in the battery case. The first trap includes a mesh material disposed outside the battery case so as to oppose and cover the gas vent valve. The second trap includes a liquid retaining material made of a non-flammable material and disposed further outward of the first trap so as to oppose and cover the gas vent valve.

The invention relates to a process medium guiding apparatus for a recombination system having a recombination device for the catalytic recombination of hydrogen and oxygen created in accumulators to form water. According to the invention, a process medium guiding apparatus for a recombination system having a recombination device for the catalytic recombination of hydrogen and oxygen created in accumulators to form water is to be provided. The process medium guiding apparatus is designed such that the recombination system is limited towards the outside and comprises at least one guiding element. The guiding element is arranged above the recombination device, so that a process medium, more particular water, is guided from the process medium guiding apparatus to at least a partial region of an interior region of the recombination system.

A suppression element includes a passivation composition supplier and a polar solution supplier. The passivation composition supplier is capable of releasing a metal ion (A), selected from a non-lithium alkali metal ion, an alkaline earth metal ion or a combination thereof, and an aluminum etching ion (B). The polar solution of the polar solution supplier carries the metal ion (A) and the aluminum etching ion (B) to an aluminum current collector to etched through thereof, and the metal ion (A) and the aluminum ion, generated during the etching, are seeped into the electrochemical reaction system. Then, the positive active material is transformed to a crystalline state with lower electric potential and lower energy, and the negative active material is transformed to an inorganic polymer state with higher electric potential and lower energy to prevent the thermal runaway from occurring.

An adhesive application apparatus and a battery production line are provided. The adhesive application apparatus includes an unwinding mechanism, a first winding mechanism, an adhesive application mechanism, and a second winding mechanism. The unwinding mechanism is configured to dispose and unwind the double-sided adhesive. The first winding mechanism is configured to peel off and wind the first release paper. The adhesive application mechanism and the winding mechanism jointly define a first path, where the first path is used to guide the adhesive strip to move forward. The adhesive application mechanism includes an adhesive application member disposed on a side of the first path, where the adhesive application member is configured to applies pressure from a side of the first path to the double-sided adhesive, so as to attach the adhesive strip on an object surface. The second winding mechanism is configured to peel off and wind the second release paper.
