NOVELTY - The apparatus (20) has an electrochemical cell (22) comprising a cathode (40) and an anode (50) supported on a solid electrolyte (30), where the solid electrolyte is Li-ion non-volatile electrolyte containing dissolved metal salt such that the cathode is constructed of a material with which lithium is known to form alloys, and the anode is constructed of lithium-ion containing material. The electrochemical cell is operable to expose lithium metal on the cathode. A power source (24) e.g. lithium-ion battery, is provided for powering the electrochemical cell.    USE - Apparatus for forming vacuum in a sealed enclosure through electrochemical reaction.    ADVANTAGE - The apparatus comprises the electrochemical cell with the cathode that are exposed to the gases in an enclosure, where the electrochemical cell is activated to cause intercalation of a reactive metal into the cathode of the electrochemical cell such that the intercalation of the reactive metal in the cathode causes the cathode to crack or fissure, which exposes the metal to react with the gases in the enclosure so as to reduce the pressure in the enclosure. The heater of the apparatus can be configured and arranged to have the ability to raise the temperature of the electrochemical cell in the order of tens of degrees Celsius, so that the ability to control the temperature of the electrochemical cell can allow for controlling the rates of the resulting reactions.    DETAILED DESCRIPTION - The cathode is constructed of one of nickel, copper, silicon and tin material. The anode is constructed of a lithium alloy e.g. lithium cobalt oxide (LiCoO2). The solid electrolyte comprises a solid polymer electrolyte (SPE) that comprises lithium hexafluorophosphate solution in polyethylene oxide (PEO). An INDEPENDENT CLAIM is also included for a method for forming vacuum in a sealed enclosure through electrochemical reaction.
