Abstract Aqueous Zn‐metal battery (AZMB) is a promising candidate for future large‐scale energy storage with commendable capacity, exceptional safety characteristics, and low cost. Acetonitrile (AN) has been widely used as an effective electrolyte constituent to improve AZMBs’ performance. However, its functioning mechanisms remain unclear. In this study, we unveiled the critical roles of AN in AZMBs via comparative situ electrochemical, gaseous, morphological analyses. Despite limited...

Gas evolution reactions in aqueous zinc metal batteries (AZMBs) cause gas accumulation and battery swelling that negatively affect their performance. However, previous work often reported hydrogen as the main, if not only, species evolved AZMBs; complexity of has been overlooked. For first time, this found CO2 reaction (CER) AZMBs, pinpointed its sources, identified electrolyte modulation strategies. Using differential electrochemical mass spectrometry, CER was detected V2O5||Zn full cells,...

Aqueous zinc-ion batteries (AZIBs) have shown promising suitability for grid-scale energy storage due to their affordability, intrinsic safety, and environmental-friendliness. However, the commercialization of AZIBs has been hindered by dissolution cathode instabilities Zn metal anode. Researchers worked improve cathode, anode, electrolyte, but relatively little attention given glass fiber (GF) membrane often used as separator. As such, we compare four commonly GF membranes (Whatman™ GF/A,...
