Graphene Nanocomposite Cathode for Advanced Space Battery, Phase I

There are potentially many different NASA applications for safe, high specific energy, and high energy density power systems for future NASA Exploration missions. Possible applications include extravehicular activities, landers and rovers. Due to its high volumetric energy density, the proposed battery may find wide applications in any weight- and volume-sensitive vehicular systems that NASA may need to accomplish its space missions. The safety feature arising from eliminating the use of lithium metal anode makes Luna's battery a better choice for human-rated power systems. Essentially, Luna's new battery will provide light-weight, high-reliability and safety replacements for many NASA applications that currently use lithium-ion batteries. The proposed battery could be used for military applications as light-weight, high-energy power sources for autonomous Unmanned Aerial Vehicles (UVA), which requires aggressive weight and volume performance improvements over state-of-the-art lithium-ion based systems. In these small or micro UVAs, our battery may be used in combination with solar panels to provide power during the daytime and the night for continuous no-landing operations in remote or hostile regions. Due to the improvements in safety and energy density Luna' battery may also find uses in commercial products such as electrical vehicles (EV) and hybrid electric vehicles (HEV) where they can completely and partially replace internal combustion engine and gasoline.
