Appendix G -- Materials and Processes for All Solid-State Batteries for Electric Aircraft: Multi-Dimensional Networked Antiperovskite Electrolytes for All Solid-State Batteries for Electric Aircraft

High-performance solid-state batteries are highly demanded for the practical application of all electric vertical take-off and landing vehicles (eVTOL). Recent studies have reported different solid-state electrolyte (SSE) such as garnet, lithium phosphorus oxynitride, etc. However, those existing SSEs have still suffered from their own limitations such as instability with alkali electrodes and severe decay of the performance due to moisture sensitivity. Herein, the overarching goal of this project, for the first time, is to develop a new SSE based on multi-dimensional networked antiperovskite (AP) with unprecedented functions. A novel and scalable liquid-phase method will be used to break the thermodynamical metastability and fabricate the advanced SSE by manipulating the building blocks. To further improve the performance of AP based SSE, a nonflammable electrolyte will be designed and synthesized as a surface wetting agent in combination with the SSE. By assembling the full cells with the novel SSE, advanced anode, and cathode, it is expected to meet the requirement by eVTOL of the five key properties including safety, energy density, power, packaging design, and scalability. The proposed project is also aligned well with the research interests of NASA research centers, such as Glenn Research Center. We plan to leverage this project to strengthen the collaboration with research scientists at NASA to improve research infrastructure and capability in South Dakota. By conducting the research activities in this proposed project, it also has the potential to develop local workforce and boost technology transfer in the field by collaborating with local companies and/or startups.

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.
