SEALED LITHIUM-ION BATTERY VALVE Russian patent published in 2018 - IPC H01M2/04 H01M2/12 H01M2/18 H01M10/52 H01M10/34 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical industry and can be used in sealed batteries for the discharge (relief) of pressure of gaseous medium from lithium-ion batteries. Technical result is achieved due to the fact that in the valve of a sealed lithium-ion battery located in the battery case, a cover is installed on the case, having channels in the form of grooves for the free exit of gas and elements for its fixation on the case, after turning around the axis, using grooves, while in the valve there are two elastic sealing elements and two thrust regulators in the form of gaskets, abutting against the cover. In both elastic sealing elements, the effect of the elastic properties of the material they are made of is used. Both elastic sealing elements have the form of flat annular plates interconnected by a membrane of the same material and arranged successively one after the other in the same plane. Cover is made with channels in the form of cuts for the free exit of gas and consists of an elastic material for its reliable fixation on the body.

EFFECT: improving the reliability of sealing the case while simplifying the design is the technical result of the invention.
