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.
