Abstract
The lithium-oxygen electrochemical couple has the potential to form the basis of a very high specific energy, rechargeable battery for very high altitude unmanned aerial systems. We propose to investigate a variety of approaches to address cycle life, reliability, and safety of the lithium-oxygen battery, both in an oxygen atmosphere and in an “air breathing” mode. In addition to addressing the performance characteristics of the lithium-oxygen/lithium-air battery we will design and build a prototype cell to demonstrate the scalability of the technology. Polymer(s) or ceramic/glass electrolytes will be the choice for the solid-state electrolytes, and may be used in conjunction with liquid electrolytes. Furthermore, we will also address battery power density.
