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

Completed Technology Project

Project Introduction

High Temperature Battery for In Situ Exploration of Venus, Phase I
Development of batteries capable of operational temperatures of 380°C and 486oC 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. More »
