Different metals can be usedbut zinc is very promising due to its disposability and nontoxic behav-ior. State estimation is quite complicated as the voltage characteristicof the battery is rather flat. Especially estimating the state of chargeis important as a secondary electrolysis process during overcharging canlead to an unsafe state. Another technique for state estimation is theelectrochemical impedance spectroscopy. Therefore, this paper describesthe process of setup and measuring a time series of impedance spectraat known states of charge. Then these spectra are used to derive anequivalent circuit. Finally the development of the circuit's parameter areanalyzed to extract most important parameters.}, language = {de} } @article{LoechteHemingGebertetal.2018, author = {L{\"o}chte, Andre and Heming, Daniel and Gebert, Ole and Horsthemke, Ludwig and Gl{\"o}sek{\"o}tter, Peter}, title = {Oxygen consumption of zinc-air batteries and theirperformance at low oxygen concentration levels}, series = {2018 16th Biennial Baltic Electronics Conference (BEC)}, journal = {2018 16th Biennial Baltic Electronics Conference (BEC)}, doi = {10.1109/BEC.2018.8600972}, pages = {1 -- 4}, year = {2018}, abstract = {Already existing primary Zinc-air batteries providea high energy density.
