Next Generation Lithium Sulfur Batteries for Mission Enabling Energy Storage Systems

Iowa State University/NASA Glenn Research Center, Johnson Space Center & Jet Propulsion Laboratory/Human Exploration & Operations Mission Directorate, Space Technology Mission Directorate, Science Mission Directorate

Lithium batteries have enabled tremendous advancements in the use of portable electronics, in the use of hybrid and plug-in electric vehicles, and in the exploration of space. For the latter, their combined light weight and high energy and power densities make them the battery of choice by NASA for many of its space exploration systems and are currently being baselined for a number of upcoming robotic and human missions. However, the demands of space exploration are significantly more critical than those of terrestrial use and NASA continues to seek increases in the energy density that can be stored in and retrieved from its batteries to enable greater capability from its manned and unmanned space exploration systems. NASA also seeks safer batteries that do not suffer from the spontaneous ignition problems of present day lithium-ion batteries and to develop new batteries that have higher current rates so that they can be used in more power intensive applications such as explorer and rover vehicles. Finally, NASA seeks to develop new higher energy density batteries that can

significantly extend the Human EVA time, yet at the same time increase the safety of these energy dense power systems to protect its astronauts during use. Specifically, the PIs seek to apply and expand their expertise in solid electrolytes, anodes, and cathodes to build research capacity and competitiveness in Iowa through the study, design, development and characterization of next generation lithium sulfur batteries (LSBs). This effort has enhanced the ongoing collaborations between the PIs, NASA Glenn and JPL, local industrial collaborators, and Iowa educational institutions.
