Revealing the effects of conductive carbon materials on the cycling stability of rechargeable Zn-air batteries

In this work, the effects of conductive carbon materials on the cycling stability and charging performance of rechargeable zinc-air batteries (RZABs) are comprehensively investigated. Unlike previous work, electrode characterization was performed only at different stages of battery cycling or after failure. Differential electrochemical mass spectrometry (DEMS) was introduced to directly monitor the gases released during the different cycles. This work not only demonstrates that conductive carbon materials have a significant impact on cycling stability, but also indicates the need for in situ gas analysis to more rigorously assess charging performance.
