Lot Acceptance, Abuse and Life Testing of Varta Lithium Polymer Pouch Cells

Abstract

The aim of this paper is to describe the qualification, characterisation and acceptance testing performed on Varta Lithium Polymer cells in order to assess their suitability for LEO cube-sat and small satellite applications. Verification of battery operational performance and safety is a multi-layered process that involves continuous assessment of cell parameters at cell, battery and system level from initial cell selection through to final battery configuration. The tests performed involved assessing individual cell performance relating to capacity under a variety of environmental conditions as well as establishing cell safety via abuse testing for small satellite systems.
