Abstract

In pursuit of lightweight, low-cost systems, the space industry has made significant investments in "high-payoff" technologies such as composite structures and high energy density batteries. These individual technologies are now relatively "mature" and are "standard" for most new spacecraft designs. Additional investment in these areas would yield only a marginal improvement over current performance. Faced with these diminishing investment returns, it is clear that future progress demands revolutionary new concepts for spacecraft subsystems.ITN Energy Systems believes Multifunctional Structures (MFS) offer the best solution to this challenge and therefore we propose development of the "LiBaCore Panel". LiBaCore stand for Lithium Battery Core, and consists of the following:-Rechargeable, high cycle life, high energy density, thin-film, solid-state lithium batteries integrated into the honeycomb structural core of a composite sandwich panel.-Flex-circuits integrated into the composite sandwich panel facesheets to interconnect batteries and terminals.This lightweight, high-energy-density power storage device will also function as the structural core in a composite sandwich panel. LiBaCore is particularly compatable with the Air Force's "cableless Space-Craft" initiative, and represents an exciting and promising new approach to achieving significant reductions in mass and volume.
