The Galileo probe Li/SO2 battery

NASA's Galileo mission to Jupiter will consist of an orbiter and a probe, the probe to descend through and analyze the Jovian atmosphere. All power for the probe will be supplied by three battery modules containing a total of 39 D size Li/SO2 cells that will be required to retain capacity for the duration of the mission (over 50 months) and then provide current at 3 to 4 amperes for 48 minutes. The design, development, and testing of this battery are described herein.

Li/SO2 Cell for Galileo

Some information on the special process controls for lithium sulfur dioxide (Li/SO2) batteries is presented with reference to how those controls affected the Galileo probe program and the instrument test vehicle program. The general considerations that go into any application for basically any type of battery system are discussed. Particular emphasis is given to some of the design tradeoffs which resulted because of the addition of the safety characteristics of the Li/SO2 system.

High energy density batteries for satellite applications

The performance requirements of high-energy batteries for terrestrial applications were examined to establish whether or not these systems showed any promise in aerospace applications. The technology assessment is reported and consists of a battery technology evaluation, preliminary engineering studies, and system selection. Major candidate systems are compared and a program schedule is provided.
