Military applications of reserve batteries

Abstract

Reserve batteries are batteries which do not give power until activated. They have a long storage life and high power capabilities which makes them useful for numerous military applications. Designs of reserve batteries include those based on movement of electrolyte (sea water, energizers and reserve silver-zinc or lithium-thionyl chloride) and thermal batteries, which are high-temperature batteries activated by heating using an internal pyrotechnic.The increasing shelf-life of lithium primary batteries and the higher energy density of lithium reserve (particularly thionyl chloride) batteries is allowing these to replace aqueous electrolyte reserve batteries in some applications. Increased energy density of recent thermal batteries makes them more attractive for applications which have previously used other reserve batteries.

Вибір Матеріалів Та Визначення Їх Електрохімічної Поведінки В Якості Катодів Хімічного Джерела Струму Ампульного Типу

“…Ампульні хімічні джерела струму як резервні батареї набули широкого використання в космічній та військовій сферах [1][2][3][4]. Для створення будь-якої незворотної електрохімічної системи потрібно мати масивний електрод зі стабільною витратою активного компонента і постійним потенціалом та каталітично активний протиелектрод.…”

“…Reserve battery is most critical and process starts from it [4]. An electronic fuze, which depends on events of an electronic nature for its safety, arming and firing functions, requires electrical energy for operating as a component of ammunition.…”

Fast-activating reserve power sources: is lead dead indeed?

“…To ensure a high reliability of electronic and electromechanic devices operating under extreme conditions, power sources of this type must comply with strict requirements, stable discharge voltage and short activation time (some 40-60 ms) even at low temperature (down to -50 °C) being among them. Their functional feature consists in the spatial separation of electrolyte from dry cells prior to activation, which ensures long shelf life (up to 17-20 years) without self-discharge and in the capability of fast activation by filling up the cells when needed [3].…”
