High Energy Density, Long Cycle Life Li-S Batteries for Space Applications

ADA Technologies, Inc. (ADA) proposes the development and subsequent manufacturing/commercialization of our high specific energy (gt;400 Wh/kg) nanoengineered lithium-sulfur (Li-S) battery technology to meet National Aeronautics and Space Administration (NASA) energy storage needs for lunar/space applications. Next generation lunar/space platforms will be equipped with significantly increased capabilities compared to todayrsquo;s systems requiring a transcendent increase in battery specific energy (gt;400 Wh/kg) while maintaining a long operational life (thousands of cycles at various depth of discharge) and long shelf/service life (multiple years). The rechargeable Li-S battery is an attractive Next Generation, Beyond Li-Ion system that can satisfy the requisite specific energy demands. ADArsquo;s solution addresses fundamental challenges associated with Li-S battery chemistries to provide performance and reliability/safety advantages, compared to state of the art (SOA). Promising results have been demonstrated in ADA preliminary studies, representing a great potential to meet NASA performance and safety goals.
