Abstract: An apparatus for forming a vacuum in a sealed enclosure through an electrochemical reaction includes an electrochemical cell comprising a cathode and an anode supported on a solid electrolyte. The solid electrolyte is a Li-ion non-volatile electrolyte containing a dissolved metal salt. The cathode is constructed of a material with which lithium is known to form alloys. The anode is constructed of a lithium-ion containing material. The cell is operable to expose lithium metal on the cathode.

Abstract: A non-evaporable getter 1 includes a mesh 3, a frame 2 which is attached to the mesh 3 and suppresses deformation of the mesh 3, and a powder-state getter material 4 which is surrounded by the mesh 3 and the frame 2, and whose particle size is larger than a mesh opening of the mesh 3.
