Abstract: Deterioration of a glass-to-metal seal in a lithium cell is prevented by protecting the exposed interior of the glass with a metal oxide or a non-conductive non-reactive polymeric material such as a fluorocarbon or a polyolefin stable in the presence of lithium and other cell components.

Abstract: An electrochemical cell is provided with means for isolating and segregating the mercury droplets formed during the electrochemical consumption of amalgamated anodic materials. The segregating means comprises amalgamable metal sheet, preferably of expanded surface area as provided by grids of screening or expanded metal lath, in contact and adjacent to the inactive face of the anode. While zinc is the exemplified anode, the grid will protect other amalgamated anodes including cadmium and lead in aqueous systems, and lithium, sodium and calcium in non-aqueous systems.

Abstract: A miniature cell 0.1 inch diameter, and 0.75 long using lithium/sulphur dioxide electrolyte complex; and the method of preparing it. A hypodermic needle sealed at its outer end serves as an anode support and current collector and also provides a conduit for injecting a liquid electrolyte into the cell.
