Solid polymer electrolytes are a better alternative to conventional flammable liquid electrolytes, as they present higher mechanical strength, lower cost, and improved safety. The project's key goals are for the feedstock material for the electrolytes to be printable, exhibit high ionic conductivity and be functional in standard battery configuration without thermal post-processing. The utilization of in-situ resources (ISRU) materials and resources available on the Lunar and Martian surface will be maximized during the preparation of the 3D printer feedstock materials (photocurable resins or inks).
