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. Lynntech’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 NASA’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.

High temperature all solid-state FIB batteries have shown promise to increase the energy density, power density, life, and safety over a wide temperature range of energy storage systems for NASA applications at high operation temperatures for inner terrestrial surface and low altitude and other systems. Additional NASA applications would include satellites, remote power equipment, telecommunications systems, remote sensors, detection devices where solar concentration heating can be harnessed.

High temperature all solid-state fluoride ion batteries can provide improved energy density, cycle life, and rate capability of energy storage systems for both commercial and military applications where operation temperatures can be elevated. Commercial applications include hybrid electric vehicles. Military applications include aircraft, military ground vehicles, and grid power systems.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
