Abstract

NOHMs propose to develop, demonstrate, and deliver high energy, lightweight, safe lithium sulfur (Li-S) batteries for use in space applications. During the Phase II project, NOHMs Technologies pursue approaches for enhancing energy density, safety, and manufacturability of larger-format pouch cells based on the most promising electrode and electrolyte compositions identified in Phase 1. We will demonstrate benchmarked improvements in performance and safety metrics in 2 to 4 Ah cells that will be tested and integrated into space applications such as space suits. NOHMs will provide full cells to demonstrate the feasibility of our system to meet NASA's 'Far Term Mission' specific energy and energy density goals. The battery technology under development by NOHMs is capable of delivering batteries with specific energies that are two times higher than today's state of the art Li-ion battery systems. For NASA missions, this can be translated into increased operational range, functionality, or payload capabilities and significantly reduced operational cost.
