Active lithium chloride cell for spacecraft power

Abstract

An active thionyl chloride high rate battery is under development for spacecraft operations. It is a 540kC (150 Ah) battery capable of pulses up to 75A. This paper describes the design and initial test data on a 'state-of-the-art' cell that has been selected to be the baseline for the prototype cell for that battery. Initial data indicate that the specification can be met with fresh cells. Data for stored cells and additional environmental test data are in the process of being developed.
