The utility model belongs to the field of batteries, particularly relates to a battery assembly, and solves the technical problems that the existing plastic shell battery is lower in mechanical strength and poor in safety during thermal runaway and the existing metal aluminum shell battery is high in thermal runaway risk. The battery assembly comprises a pressure-bearing shell and a battery unit positioned in the pressure-bearing shell; the battery unit comprises a sealing shell and n electrode assemblies positioned in the sealing shell; the sealing shell is a plastic shell; the strength of the pressure-bearing shell meets the strength requirement for the shell in the thermal runaway stage, and a second explosion venting part is arranged on the pressure-bearing shell. A first explosion venting part is arranged on the sealing shell, an explosion venting channel is arranged between the pressure-bearing shell and the first explosion venting part of the sealing shell, and the explosion venting channel is communicated with the second explosion venting part. According to the utility model, the explosion venting channel is arranged between the two shells in a matched manner, so that the safety and the reliability of the battery assembly are remarkably improved while the advantages of the plastic shell are reserved.

The utility model belongs to fire smoke technology field, concretely is a kind of fire smoke delaying diffusion device, including installation frame;The top of installation frame is fixedly installed with smoke collecting plate, the both sides of smoke collecting plate are fixedly installed with ceiling, the inner wall of smoke collecting plate is provided with smoke guide mechanism, the inner wall of smoke collecting plate is provided with barrier mechanism;The top of smoke collecting plate is provided with release mechanism;The top of smoke collecting plate is provided with smoke exhaust component;Through the setting of partition, guide plate, discharge pipe, flame-retardant isolation cloth, guide slot, sliding block and gravity plate, partition can be separated into small piece with smoke, so that smoke can be orderly discharged, prevent accumulation in the inner wall of smoke collecting plate, guide plate can guide smoke to discharge pipe, so that it is transported to smoke exhaust component, the cooperation of flame-retardant isolation cloth and gravity plate can realize rapid deployment, so that smoke can be rapidly isolated, prevent its diffusion.
