Abstract
Iodine‐activated miniature cells, , with solid silver iodide as the electrolyte, have been studied at 150°–550°C. In this range of temperatures the cells have the following characteristics: complete conversion of the consumable silver anode into its electrical equivalent, open‐circuit voltage of 0.67 v, short‐circuit currents up to 18 ma, capacity of 10 ma‐hr, energy output up to 5 mw‐hr/cell, a definite activation temperature obtained by selecting a suitable source of iodine vapor, and indefinitely long shelf life below that temperature. The size of the smallest cells is 0.15 cm in diameter and 0.5 cm in length.
