✦ Synopsis

A comparison of the behaviour of commercial electrochemical manganese dioxide (y_MnO,) and non-stoichiometric anodic Mn,O,(OH), was made. Anodic oxide proves to he composed mainly by MnO, (ramsdellite) and MnOOH (manganite), and contains more water and OH-than y-MnO,. Hydroxide ions were shown to determine the ionic conductivity of Mn,O,(OH), which, in turn, strongly affects the rate of electroreduction.
