An update of the ground testing of the Li-ion batteries in support of JPL’s 2003 Mars Exploration Rover Mission

Abstract

This paper provides further detail to previously reported results of the RBAU testing program, especially with regard to the life characteristics. To date, the lithium-ion batteries (fabricated by Lithion/Yardney, Inc.) have been demonstrated to far exceed the requirements defined by the mission, both on Mars and on the ground, and are projected to support an extended mission (> 4 years).
