Experimental Analysis of a Pyrotechnic Compositions Battery

A type of pyrotechnic compositions battery was developed to meet the requirements of a subminiature and fast-activated reservoir battery which would be applied to shell fuze. This battery was activated by the pyrotechnic compositions contained in the electrodes. Once the ignition impulse worked, the pyrotechnic compositions took fire immediately and melted the electrolyte. Then the rest pyrotechnic compositions served as anode and cathode. The battery began to discharge. Electrical property tests taken on the prototype cells indicated that the performance of the pyrotechnic compositions batteries were improved greatly compared with common fuze batteries. Such property parameters contained volume, activation time and energy density. (C) 2011 Published by Elsevier Ltd.
