A breathable plug designed for use with a breathable plug fixture. The plug allows gas to pass through while preventing the passage of liquids. It includes a resilient external thread that enables installation via an interference push fit. The external thread also features one or more wings positioned between the root and the crest of the thread.

A battery cell includes a housing, an electrode assembly, and a one-way valve. The housing has a wall portion, the electrode assembly is accommodated within the housing, the one-way valve is disposed on the wall portion, and the one-way valve is configured to discharge gas from inside the housing. Through provision of the one-way valve on the wall portion of the housing, the one-way valve can open unidirectionally to discharge gas inside the housing to the exterior of the housing, allowing gas generated inside the housing during normal operation of the battery cell to be discharged to the exterior of the housing through the one-way valve.

Disclosed are a battery cell case having a dissoluble mechanism and a high-capacity battery. The battery cell case comprises at least one dissoluble mechanism, which comprises an isolating assembly and a dissoluble assembly; the battery cell case is provided with an opening, where the isolating assembly and the dissoluble mechanism are arranged sequentially in a direction away from the battery cell case; when the dissoluble assembly contacts with electrolyte outside the battery cell case, the isolating assembly is opened because the dissoluble mechanism is dissolved, thereby the interior of the battery cell case communicates with the exterior of the battery cell case. The high-capacity battery comprises at least two battery cells and an electrolyte storage pipeline, where the electrolyte storage pipeline comprises a main pipeline and a plurality of branch pipes, the branch pipes are in one-to-one correspondence to the openings of the battery cell cases.

Mechanisms and methods for pressurized fluid injection, evacuation, and venting from containment vessels, such as the housing for a battery or capacitor, using an elastomeric sealing vent mechanism are disclosed. The invention describes designs and methods in which a fluid injection port is plugged with an elastomeric sealing vent, serving as both the primary fluid sealing mechanism and the safety relief mechanism in case of over-pressurization or over-heating.
