    Abstract: PURPOSE: A manufacturing method of a nanostructured manganese dioxide is provided to manufacture the nanostructured manganese dioxide which has the high catalyst activity which is usable in the metal air secondary battery through the simple process by using the hydrothermal synthesis. CONSTITUTION: A nanostructured manganese dioxide has a nanorod shape in which the diameter is 15-110 nm and the length is 200-500 nm. The nanostructured manganese dioxide comprises as the tetragonal α-manganese dioxide crystal structure. The nanostructured manganese dioxide comprises K+. The manufacturing method of the nanostructured manganese dioxide comprises the following steps: a precursor which includes Mn2+ and an oxidizing agent which includes MnO4- are dissolved in water, and a reacting solution is prepared; the reacting solution is synthesized with the hydrothermal synthesis; and the precipitate which is generated from the hydrothermal synthesis reaction is collected. The precursor and the oxidizing agent have the mole ratio of 1:0.5-1:2. The precursor is the manganese sulfate (MnSO4), and the oxidizing agent is the potassium permanganate (KMnO4). The hydrothermal synthesis is performed in the autoclave at 140-160°C for 20-30 hours.
