Abstract

We report here the direct synthesis of a hexagonal form of manganese dioxide using mild hydrothermal methods. The reaction of potassium or sodium permanganate in water at 170°C leads directly to potassium or sodium manganese dioxide, Alk_≈0.25MnO₂·0.6H₂O, with a R3m rhombohedral structure like Li_x(H₂O)TiS₂ and a 7 Å repeat distance indicative of a monolayer of water between the manganese dioxide layers. This manganese oxide reacts readily and reversibly with lithium ions.
