Feasibility Demonstration of Prussian Blue Sodium-Ion Batteries in Lunar Applications.

Prussian blue sodium-ion batteries are an emerging energy storage technology with unique characteristics. This technology boasts the highest available power density in any current battery technology on the market, potentially unlocking new possibilities for power system design and diverse applications previously deemed unattainable. Prussian blue sodium-ion technology is proven on Earth, but it has not yet been rigorously tested through laboratory experimentation to demonstrate feasibility for lunar missions. This project aims to demonstrate the utility of Prussian blue sodium-ion batteries within the Moon to Mars missions with focus on lunar applications. The secondary aim is to characterize the battery materials and identify functional relationships for the battery materials that will enable design of Prussian blue sodium-ion battery packs. It is expected the outcome of this project will culminate with the delivery of a design document and design review of a battery pack suitable for delivery to the moon for lunar testing.

Prussian blue sodium-ion batteries can support missions and CONOPS in power beaming, rapidly recharging lunar rovers, pulsed high power communications, high power tools, and could eventually be used in electromagnetic rail systems for transit of people and material between various points on the lunar surface. These objectives support meeting the following NASA civil space shortfall IDs: ID 1595: Energy Storage to Enable Robust Long Duration Operation on Moon and Mars ID PWR – 510: Low Temperature Secondary Battery Modules up to 50 kWhe increment ID PWR – 745: Energy Storage for Planetary Surfaces ID PWR – 1103: Common Modular Building Blocks for Energy Storage with Performed Performance Relative to SOA. ID 1592: High Power, Long Distance Energy Transmission Across Distributed Lunar Assets ID PWR – 508: Wireless Power Transmission up to 10 kWe increment ID 1618: Survive and Operate through the Lunar Night ID THERMAL – 522: Freeze Tolerant Thermal Components Prussian blue sodium-ion technology is already commercialized within the data center, critical power, and AI/ML industries. Airtronics LLC is working with the battery manufacturer to integrate the technology into alternative use cases. Use cases already pursued: Directed Energy Weapon System Power Arctic Power for Forward Operating Bases and Microgrids Armored Vehicle Power Systems The work proposed seeks to extend the battery capabilities to non-terrestrial environments and seek to demonstrate feasibility of this technology in alternative mission/application approaches.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
