NASA's future ESMD, SMD, SOMD and ARMD missions demands high energy density batteries. This energy storage technology is for space applications such as EVA, Lander, and Rover. Provides more electric aircraft and other transportation applications, with lower cost and no resource issues compared with lithium (Li) while retaining the majority of Li metal's electrochemical qualities. Commercial potential for Na-O2 is considerable as virtually all battery powered products in the commercial and military market demand greater energy capacity per unit mass and/or volume. The 2012 global market for rechargeable LIB technology was near $11.7 billion. As demand grows, a $25 billion market is projected by 2016 for high capacity batteries.
