Abstract: The specification discloses a consecutively wound or stacked battery system and a method for making these devices. In one aspect, battery cells are wound consecutively, separated by insulating layers, to form an integral battery system capable of producing multiple voltages. In a second, but related, aspect, multiple battery cells are wound consecutively on a large diameter mandrel, cut in a radial plane, and laid flat to form stacked battery systems capable of producing multiple voltages. Whether remaining in the consecutively wound configuration, or being cut to become a stacked cell configuration, each cell in these configurations may be selectively coupled to other cells within its consecutive winding or stack to produce desired output voltages and current ratings. In the case of the stacked battery system, this battery system may be selectively cut to provide amperage capacities to order.

Abstract: An electrical power system for a spacecraft or other vehicle or structure comprising a structural member containing an integrated solid-state power source is disclosed. The power source includes a solar cell system and an energy storage system that are combined into a single unit or package, and in certain embodiments, are configured into the shape of a flexible aerobot balloon or a rigid nanosat surface panel. The power components of a preferred lightweight power unit, include thinly layered photovoltaic cells, a rechargeable lithium solid polymer electrolyte battery, a capacitor, electronics and thermal management capability.
