Abstract: Material is incorporated in each of the cell separator membranes of an electrochemical cell having a layered construction wherein a plurality of commonly connected metal anode layers and a plurality of commonly connected cathode layers are arranged in a closely packed, stacked sandwich construction, separated by a plurality of thin insulating separator membranes which gives each cell separator a known resistance value which can be measured thereby allowing total cell resistance to be readily tested.

Abstract: A reserve activated electrochemical cell in a battery embodiment uses a tubular electrolyte storage compartment arranged in a concentric spiral having similar diameter turns thereof located on a common axis. The tubular spiral is assembled concentrically with a battery plate stack container in a volumetrically efficient package with a first end of the spiral having an outwardly projecting flange located adjacent to one wall of the stack container. An intermediate annular spacer is located between the flange and the wall of the stack container to provide a fluid-tight seal therebetween, to define a fluid channel therethrough and to separate different materials forming the stack container and the electrolyte storage spiral. A first rupturable diaphragm is attached with a fluid-tight seal across the inner diameter of the first end of the tubular spiral facing the battery stack to maintain hermeticity therein.
