Abstract
A self-limiting electrochemical cell such as a lithium-sulfur dioxide cell having a non-porous, non-ion-permeable separator between the anode and cathode so as to control the passage of electrolyte and ion-transfer between the working electrodes thereby controlling the current drain based on the controlled amount of electrolyte. The invention provides a convenient method of controlling the drain rates of an electrochemical cell and permits utilization of conventional cells such as the lithium-sulfur dioxide, lithium-thionyl chloride, or lithium-sulfuryl chloride cells in applications not previously possible.
