LITHIUM PEROXIDE PRIMARY ELEMENT ABSTRACT OF THE DISCLOSURE In a galvanic primary element of the system Li/H2O2, the aqueous cathode depolariser H2O2 is fixated as a polyurethane gel. It can thereby be controlled and caused to react with the anode metal in accordance with the current drain requirements. This is accomplished using a ram to press the gel toward a conductor which covers the lithium anode, which may take the form of a metal grid and/or a gas diffusion electrode. The oxygen which forms in the working layer through catalytic decomposition of hydrogen per- oxide creates a gas bubble when the current is interrupted or the ram is stopped, thereby interrupting the further supply of hydrogen peroxide to the catalyst.
