Analysis of critical battery parameters for space applications

Abstract

This thesis deals with the analysis of lithium-ion batteries from the point of view of temperature. The aim is to find out at which temperature and C value the lithium plating process starts in the battery by means of non-destructive methods. This process is undesirable for the functioning of lithium-ion batteries as it causes capacity reduction and cell degradation. In this study, commercial cells from GOMspace were selected as the test batteries. GOMspace will be able to use the results of the research to optimize its devices while avoiding lithium plating, which will increase battery life.
