SEALED LITHIUM-ION BATTERY VALVE Russian patent published in 2018 - IPC H01M2/12 H01M2/18 H01M10/52 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular, to a valve of a sealed battery for the discharge of pressure of a gaseous medium, and can be used in the manufacture of lithium-ion batteries. In the proposed valve, located in the battery case, a cover is installed on the case that has channels in the form of openings for the free release of gas, as well as elements for its fixation on the body after rotation around the axis, while in the valve there are two elastic sealing elements and two thrust regulators-gaskets resting against the lid, which use the effect of elastic properties of the material from which they are made. Both elastic sealing elements are in the form of flat annular plates interconnected by a membrane of the same material, and arranged in series one above the other. Cover is made with channels in the form of cuts for the free exit of gas and from an elastic material for its reliable fixation on the body.

EFFECT: improving the reliability of sealing lithium-ion batteries is a technical result of the invention.
