Rechargeable Thermal Batteries for Airborne Systems

Description:

OBJECTIVE: Provide a prime power system using rechargeable thermal batteries suitable for airborne systems. 

DESCRIPTION: Demonstrate the feasibility of using rechargeable chemical batteries as prime power sources on airborne platforms beginning with an analysis of the current state of the art and progressing to a completed system. 

PHASE I: Generate a report on the available state of the art in chemical thermal batteries. The report will demonstrate an understanding of all available battery chemistries. The report must describe the capabilities of the available chemistries including: Energy per cubic cm, weight per cubic centimeter, current per unit area, operational temperature range, recharge efficiency, recharge rate, and number of recharge cycles. The report will include a trade-space matrix of these capabilities, a description of how to advance the state-of-the-art, and summary of commercialization opportunities for advancing the state-of-the-art. 

PHASE II: Develop a design for a thermal battery for airborne systems based on specifications that will be provided. The design must finalized in this phase. A prototype system will be constructed and tested at an Air Force Facility to demonstrate that the design meets the provided specifications. 

PHASE III: Refine the prototype design from phase II into a commercial product. Develop a manufacturing system to produce commercial volumes of rechargeable thermal batteries that satisfy Air Force and other customer needs.
