Analysis of Reaction and Transport Processes in Zinc Air Batteries

This book contains a novel combination of experimental and model-based investigations, elucidating the complex processes inside zinc air batteries. The work presented helps to answer which battery composition and which air-composition should be adjusted to maintain stable and efficient charge/discharge cycling. In detail, electrochemical investigations and X-ray transmission tomography are applied on button cell zinc air batteries and in-house set-ups. Moreover, model-based investigations of the battery anode and the impact of relative humidity, active operation, carbon dioxide and oxygen on zinc air battery operation are presented. The techniques used in this work complement each other well and yield an unprecedented understanding of zinc air batteries. The methods applied are adaptable and can potentially be applied to gain further understanding of other metal air batteries.

Daniel Schröder works currently as research assistant at the Justus-Liebig-Universität Gießen, Physikalisch-Chemisches Institut, AG Janek and is group leader of the metal air battery research group, analyzing Li-, Na- and Zn-air batteries.
