Abstract
Future space exploration energy-storage needs span a wide range of requirements. NASA's Exploration missions will require safe, human-rated, high specific energy, high energy density and high efficiency-storage systems that can be used in space and on the moon and Mars. These energy storage devices need to be used in applications such as Landers, Rovers, and extravehicular activities (EVAs). NOHMs Technologies, Inc. proposes to develop a novel battery based on Lithium-Sulfur chemistry that has a demonstrated specific energy of 1875 Wh/kg with a theoretical specific energy of 2600 Wh/kg, while yielding a dramatic 3-4x reduction in weight, size, and cost. The proposed technology is based on innovative sulfur-infused carbon composite cathode materials developed at Cornell University. These materials overcome the poor cycle life problems that have plagued Lithium-Sulfur batteries by encapsulating sulfur in nanometer-sized mesoporous carbon capsules. In addition, the proposed Phase I research will focus on the development of stable, non-flammable, non-volatile, nano-hybrid electrolytes and separators that overcomes lithium dendrite formation in all lithium based battery configurations, significantly enhancing their safety. Phase I will demonstrate the potential of our proposed system to meet the performance parameters specified by NASA.
