ABSTRACT:
In a galvanic primary cell, the anode mixture of a zinc-alkaline electrolyte gel is displaced by the introduction of a hollow body into the concentrically arranged anode space so that the zinc powder is fixed in a layer oriented toward the cathode of the cell, ensuring proper discharge, and so that the aqueous portion of the anode mixture can escape inside the displacement body through narrow openings in the body's wall. By attaching the displacement body to the negative electrode conductor, the current drainage can be improved by making at least part of the displacement body of a metallically conducting material.
