Heat Generating Compositions for Thermal Batteries.

摘要

Thermal batteries are widely used as independent current sources with long storage life and the ability to operate over a wide ambient temperature range of -54 to +71 C. A number of pyrotechnic materials may as a rule be used as sources of thermal energy to provide ionic conduction in a molten electrolyte and to maintain the working temperature of the battery during the discharge of the electrochemical elements (EKhE). The reliability of ignition of the heat generating elements (NE) is a fundamental problem which requires a solution before they may be considered for use in thermal batteries. In this connection it is reckoned that a fundamental item in the technical specification of a thermal battery is the activation time, ie the time from the moment of application of the electrical impulse to ignite the NE to the moment of achieving maximum power from the EKhE.
