PYROTECHNICAL CURRENT SOURCE Russian patent published in 2009 - IPC H01M6/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to devices converting electrode pyrotechnical composition chemical energy into electrical power, particularly to batteries of high-temperature standby non-recoverable current sources. It can be used for supplying onboard hardware, actuators and control devices etc. In compliance with this invention, proposed pyrotechnical current source comprises voltaic battery placed in a jar, furnished with isolated terminals, and representing pyrotechnical charges. Aforesaid battery features with surplus oxidiser in cathode and surplus combustible in anode. Separators made from asbestos dispersed in electrolyte separate anode and cathode. Electrolyte comprises metal fluorides and zirconium dioxide. Current terminals representing metal plates made from foil with thickness making 11 to 13% of that of voltaic cells, and connected to electric igniter via igniting circuit interconnect voltaic cells. The said circuit comprises pyrotechnical heaters interconnected with the help of igniting tape. Note here that there are slots made in the jar opposite the current terminals.

EFFECT: higher reliability.
