Abstract
A water-activated, primary reserve battery for use in an environment, such as the ocean, that provides an environmentally safe battery, especially useful in sonobuoys. The battery includes the use of cuprous iodide as a cathode and magnesium as the anode in an array to provide voltage, amperage, and operational time equivalent to conventional lead chloride batteries. Once the sonobuoy is no longer useful as it deteriorates in the environment, no lead will be presented into the ocean. The structural frame members protect the cuprous iodide which is brittle in a rigid array and provides for proper venting of gas and sludge formation to insure efficient operation of the battery.
