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. In the valve a sealed lithium-ion battery, located in the battery case, a lid, having channels in the form of grooves for the free release of gas, is installed in the case, and for fixing it in the case there is a retaining ring, there is also an elastic sealing element – a cuff and a stop regulator abutting the lid, a second similar elastic sealing element and a stop regulator are further introduced into the structure, wherein the stop regulators are spring-loaded, a second locking element in the form of a retaining ring is installed in the valve for retaining the sealing elements with possible vacuuming of the battery cavity, wherein the sealing elements are made in the form of disc cuff and are arranged sequentially one above the other.

EFFECT: technical result achieved in the proposed sealed lithium-ion battery valve, is the increased reliability of sealing of the case and simplified design.
