Toward stimulated by defects functionality in manganese(IV) oxide materials

Abstract

Manganese dioxide obtained by electrolytic doping technique was subjected to investigations of influence of cationic additives in an electrolyte on defects in structure and prospectives of improvements in its functionality. The Chabre-Pannetier model was used for this purpose. The results indicate on the variability of γ/β- γ/α-polymorphs intergrowth ratios, and twinning. There is a necessity to expand single phase Chabre-Pannetier model based on ramsdellite structure matrix towards multiphase "open structure" polymorphs that are frequently occurred in electrodeposited samples of manganese dioxide.
