Abstract

In its on-going 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 "mature", and are "standard" for most new spacecraft designs. Additional investment in these areas would yield only a few percent improvement over current performance. Faced with these "diminishing returns", it is clear that future progress demands revolutionary new concepts for spacecraft subsystems.ITN Energy Systems believes that this challenge can best be met using Multifunctional Structures, and to this end proposes herein the "LiBaCore Panel". "LiBaCore" stands for Lithium Battery CORE, and consists of the following: 1. Thin-Film Solid-State Lithium Battery with High Energy Densy and Long Life 2. Thin-Film Battery Formed into "Honeycomb" ration, and Used as Structural Core in Composite Sandwich Panel. attery Terminals Connect to Flex-Circuit on MFS Composite Facesheets Our concept is for a lightweight, high energy-density power storage device which doubles as structural core in a composite sandwich panel. LaBaCore is particularly compatible with the Air Force's "Cableless Spacecraft" initiative, and represents an exciting and promising new approach to achieving significant reductions in mass and volume.
