A valve device and an assembled battery according to which even if the valve device operates, deterioration of an outer layer of a storage body is unlikely to be accelerated. The valve device is attached to a first storage body that stores a battery. The valve device includes an attachment part, a valve device main body, and a gas passage part. The attachment part is attached to the first storage body. The valve device main body reduces pressure inside the first storage body in a case where the pressure increases due to gas produced inside the first storage body. The gas passage part is between the attachment part and the valve device main body, and allows gas that passes through the attachment part to pass through the valve device main body. The valve device main body is located outward of an outer periphery of the first storage body.

A battery pack includes battery cell including a discharge valve opened when an internal pressure exceeds a set pressure, and case housing battery cell. Exhaust duct through which a discharge gas is discharged from the discharge valve to an outside of the case is disposed in the case, a discharge side of exhaust duct is opened to the outside of the case, and an inflow side of the exhaust duct is opened to an inside of the case, a diffusion space of the discharge gas is provided inside case, the discharge valve ejects the discharge gas into the diffusion space, and the discharge gas of the diffusion space is discharged to the outside of the case via exhaust duct.

A battery pack includes battery cell including a discharge valve, and case housing battery cell. Case includes a plurality of fume ventilation holes through which discharged gas jetted from the discharge valve is expelled out of the case, and diffusion gap is provided between discharge valve side end surface of battery cell and a case inner surface, with flameproof cover disposed in diffusion gap. Additionally, expansion space for the discharged gas diffused by flameproof cover is provided inside case, and the direction of expelling the discharged gas is changed to a direction intersecting a direction in which the discharged gas is jetted form the discharge valve. Expansion space communicates with diffusion gap and with fume ventilation holes, and a direction changing portion that changes a direction of the flowing gas is provided at corners of the case. In the battery pack, the discharged gas jetted from the discharge valve collides with flameproof cover, fills expansion space via diffusion gap, is changed in direction in expansion space to diffuse into the plurality of fume ventilation holes, and is expelled out of the case.

A top cover assembly includes a top cover, a connecting element, and a pressure relief valve. The top cover is configured to be connected to a case of the battery cell and provided with a through hole. The connecting element is arranged on the top cover and provided with an installation hole communicating with the through hole and a first channel extending to the outside from a hole wall of the installation hole. An opening, communicating with the outside, of the first channel is provided with a first gas permeable membrane. The pressure relief valve is arranged in the installation hole, is configured to slide in the installation hole under a pressure, and is provided with a second channel.

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 battery includes a battery element, housing body, and valve device. The housing body includes at least one laminate and an interior space wherein the battery element is housed, a first housing portion covers the interior space from a first side in a thickness direction, and a second housing portion that covers the interior space from a second side opposite to the first side in the thickness direction. The valve device attaches to the housing body and makes the interior space communicate with an external space. A joined edge portion is formed in the housing body by the first and second housing portion being fused along respective peripheral edges. The valve device is between the first and second housing portion in the joined edge portion, and an inner end of the valve device protrudes from an inner edge of the joined edge portion toward the interior space.

The discovery of the method of extracting hydrogen gas from water and saving the high-energy hydrogen gas is a system used by acid-lead batteries and their electrolyte replacement, which removes hydrogen from the water during charging, and then the electricity consumed for this purpose. The battery float charge mode is stored in the battery by chemical reactions. Also, by reversible reactions, a little more than the hydrogen gas is released into the normal amount of gas from the battery houses. By this method, the practical steps are to finalize the sample during the Gaseous hydrogen is recommended for industry and industry.
