High Temperature Battery for In Situ Exploration of Venus, Phase I

Development of batteries capable of operational temperatures of 380°C and 486^oC with a specific capacity 200 Wh/kg for use as a power source on the Venusian surface and for planetary probes in similar high temperature atmospheres and where ambient pressures of 90 atmospheres are to be expected. These conditions are well beyond most conventional battery technologies, except those experienced by thermally activated batteries that use a Li(Si)/FeS?2 couple. This proposal provides for the novel approach of using proven expertise from thermal batteries to develop high temperature space batteries. The approach will be to first determine the optimum cell chemistry from potential candidate systems and test via cells. Next, verification of cell performance at temperatures will be made. Design of a robust battery/cell container using super nickel alloys such as Inconel 718 will be made. Stress and dynamics analyses will be made on the final mechanical design that will be verified by test.

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.
