Comparison of aluminum silver oxide and lithium oxyhalide batteries performances for underwater weapons propulsion

摘要

An important effort is discussed to offer electrical propulsion alternatives based on aluminum/silver oxide and lithium/oxyhalide electrochemistries. The differences between the application ranges of the lithium/oxyhalide and the aluminum/silver oxide technologies are: fast discharge, medium energy, high volumic density requirements for the Al/AgO technology application; and long discharge, high energy, high specific energy density for the lithium/oxyhalide technology application. Due to the small difference (approximately 10% for the specific energy) between the two technologies, considerations such as quietness, safety, shelf life or cost can impact on the final system selection.
