Fluoride Ion Solid State Battery for Terrestrial Venus Applications

Space energy storage systems are required to enable/enhance the capabilities of future planetary science missions. Venus aerial and surface missions pose challenges for energy storage systems where the temperature and pressure can be up to 460 Celsius and 92 bars, respectively. Therefore, high temperature batteries are significantly needed for future long duration Venus missions. Lynntech proposes to develop high temperature all solid-state Fluoride-ion batteries (FIB) using a solid-state electrolyte, and high capacity electrodes with excellent chemical and thermal compatibility with the electrolyte. Lynntechrsquo;s advanced all solid-state batteries can provide high energy, high power, and long life with high safety and reliability over a wide temperature range of 150 to 500 Celsius. During Phase I, Lynntech will assess the viability of the most promising electrodes and electrolyte formulation, determine the performance of components in full cells, and deliver lab-scale cells to NASA. During Phase II, Lynntech will optimize the components and prototype cells to meet NASArsquo;s cell performance goals. The advanced high temperature all solid-state Li-ion batteries can provide significant mass and volume savings, as well as operational flexibility for NASA exploration missions.
