Abstract
Excellatron Solid State, LLC (ESS) proposes an innovative lithium oxygen energy storage system focused on High Altitude Airship (HAA) applications. This project will result in battery technology that has the potential for: ¿Specific capacity that is eight to ten times that of conventional lithium batteries ¿High standby and recharge cycle life ¿Safe operation ¿Low cost Regenerative fuel cells have been examined as a means for achieving high specific energy storage capacities using electrochemical cells. However, Hydrogen storage and mass transport requirements have constrained broad scale use of this approach. On the other hand, lithium metal as an anode material offers low density and the high electrochemical capacity making it an optimum material for electrochemical energy storage applications. But lithium is a difficult material to work with due to its inherent instability in air and water. For rechargeable batteries, lithium reactions that create high energy are difficult to reverse. This proposal offers solutions to these problems resulting in storage cells having energy capacities that are an order of magnitude greater than those available using conventional battery technologies. This technology is also anticipated to be modular and easily scalable.
