Assessment of Lithium-based Battery Electrolytes Developed under the
NASA PERS Program

Recently, NASA formally completed the Polymer Energy Rechargeable System (PERS)
Program, which was established in 2000 in collaboration with the Air Force Research
Laboratory (AFRL) to support the development of polymer-based, lithium-based cell
chemistries and battery technologies to address the next generation of aerospace
applications and mission needs. The goal of this program was to ultimately develop an
advanced, space-qualified battery technology, which embodied a solid polymer
electrolyte (SPE) and complementary components, with improved performance
characteristics that would address future aerospace battery requirements.

Programmatically, the PERS initiative exploited both interagency collaborations to
address common technology and engineering issues and the active participation of
academia and private industry. The initial program phases focused on R&D activities to
address the critical technical issues and challenges at the cell level. A variety of cell and
polymeric electrolyte concepts were pursued as part of the development efforts
undertaken at numerous governmental, industrial and academic laboratories.
Numerous candidate electrolyte materials were developed, synthesized and optimized
for evaluation. Utilizing the component screening facility and the “standardized” test
procedures developed at the NASA Glenn Research Center, electrochemical screening
and performance evaluations of promising candidate materials were completed.

This overview summarizes test results for a variety of candidate electrolyte materials that
were developed under the PERS Program. Electrolyte properties are contrasted and
compared to the original project goals, and the strengths and weaknesses of the
electrolyte chemistries are discussed. Limited cycling data for full-cells using lithium metal
and vanadium oxide electrodes are also presented. Based on measured electrolyte
properties, the projected performance characteristics and temperature limitations of
batteries utilizing the advanced electrolytes and components have been estimated.
Limitations for the achievement of practical performance levels are also discussed, as
well as needs for future research and development.
