Abstract

A new morphology of manganese oxide in the form of nano-fibers was synthesized using a novel synthetic route, and structurally characterized using high-resolution transmission electron microscopy. The obtained manganese oxide, doped with potassium, adopts a hollandite-type structure with "few useful defects" which provide an open tunneled structure in three-dimensions. This characteristic is actually believed to improve, to a high extent, the ionic conductivity of the material and exhibits the doped hollandite-type manganese oxide as a highly promising candidate for electrochemical applications such as rechargeable batteries.
