PYROTECHNICAL SOURCE OF ELECTRIC CURRENT Russian patent published in 2014 - IPC H01M6/20 

FIELD: electricity.

SUBSTANCE: pyrotechnical source of electric current represents a battery of high-temperature galvanic cells (HTGC) made as a set of multilayer pyrotechnical charges with oxidiser excess in the cathode and flammable material excess in the anode divided by an asbestos separator dispersed in electrolyte containing metal fluorides and zirconium dioxide connected in series by means of current taps made of aluminium foil and coupled with but end pyroheaters and flammable strip. Optimisation of thermal and electrochemical modes for oxidation-reduction processes in HTGC is ensured by the claimed quantitative and qualitative composition of electrodes and separator as well as by their optimal thickness.

EFFECT: reduction of ramp-up time and increase of HTGC run duration.
