Preparation and properties of manganese dioxide studied by QCM

Electrodeposition and cycling of MnO 2 was tested by cyclic voltammetry and electrochemical quartz crystal microbalance (QCM). The electrodeposition from manganese sulfate and the material cycling are accompanied by strong and almost reversible water sorption close to the stoichiometric ratio 3:1. S...

Zusammenfassung:Electrodeposition and cycling of MnO 2 was tested by cyclic voltammetry and electrochemical quartz crystal microbalance (QCM). The electrodeposition from manganese sulfate and the material cycling are accompanied by strong and almost reversible water sorption close to the stoichiometric ratio 3:1. Similar reversible sorption of water was observed also on solid MnO 2 deposited as an “ink” (slurry) with PTFE as a binder on the QCM probe.
