Abstract: A method for cutting lithium metal into a plurality of pieces, and a device for accomplishing the method, are disclosed, comprising the steps of positioning a quantity of lithium metal at a predetermined position between an anvil means and a cutting means which are positioned in operating relationship with each other. A thin flexible film, preferably a plastic, is interposed between the blade and the lithium such that when the blade is forced against the anvil with sufficient force to cut the lithium, the film prevents contact of the blade with the lithium. Indexing of the lithium and the film after each cut permits repetitive cutting to provide a plurality of pieces from the lithium metal stock.

Abstract: 1. Multiple thermal cell construction comprising a cylinder having heat source material therein and forming one electrode of a cell, dry electrolyte in contact with the outer surface of said cylinder, a metal band enclosing said electrolyte and forming another electrode of said cell, a metal band on said cylinder in spaced and insulated relation with respect to said electrolyte and forming an electrode of another cell in series with said first mentioned cell, dry electrolyte in contact with said band and an outer band contacting said last mentioned electrolyte and forming another electrode of said last mentioned cell.
