Abstract
A comparison of the behaviour of commercial electrochemical manganese dioxide (gamma-MnO2) and non-stoichiometric anodic Mn(x)O(y)(OH)z was made. Anodic oxide proves to be composed mainly by MnO2 (ramsdellite) and MnOOH (manganite), and contains more water and OH- than gamma-MnO2 . Hydroxide ions were shown to determine the ionic conductivity of Mn( x)O(y)(OH)z which, in turn, strongly affects the rate of electroreduct ion.
