E-Book Overview
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.

During this period, I had the pleasure to work alongside many people and I want to express my gratitude to them at this point. First of all, I thank Prof. Dr.-Ing. Ulrike Krewer who gave me the opportunity to work on the topic of zinc air batteries, and who guided and encouraged me throughout the entir
