Abstract Scope |
Additive manufacturing paves the way towards the in-space/on-surface development of shape-conformable energy storage devices for applications that will support Human’s mission on the Moon and Mars: spacecraft, portable power devices, robots, and large-scale power systems. Batteries will be able to better fill unique volumes, taking advantage of the dead space, with a view to maximize the energy storage capability. Although lithium-ion batteries are currently the most common choice on Earth, sodium-ion batteries are of particular interest for NASA due to the relative abundance of their materials and precursors in the Lunar and Martian regolith. In this presentation, the development of a composite photocurable resin loaded with TiO2 negative electrode material and conductive additives, to feed a vat photopolymerization printer, will be discussed. The influence of the printing parameters and additional thermal post processing step on the resulting electrochemical performances and mechanical integrity of the printed items will be reviewed. |
