Abstract: A combined electrical filter and interrupted energy source for a space satellite or other DC powered apparatus. The disclosed filter battery preferably employs an array of nickel-cadmium cells each having circular configured electrodes parallelly disposed along an axis and interconnected by axially aligned inter-call conductors which attach to central areas of the electrodes. The resulting filter battery is electrically comprised of an array of selected value electrical elements disposed in a parallel-series configured network and related to elements of the battery cell structures. Filtering accomplished with the filter battery achieves high electrical energy per pound storage density, low electrical impedance, long charge/discharge cycle life, large current delivering ability and more constant voltage output in comparison with conventional electrolytic capacitor filter elements and other cell configurations.

Abstract: A lightweight, high energy density, secondary cell battery suited for use as a battery filter element in an electrical network, particularly in space mission hardware. A pseudo-bipolar cell configuration with simple, effective electrolyte sealing and low electrical impedance characteristics is included, along with a sequence for fabricating and assembling a preferred cell arrangement.
