example 1

[0064] 0.169g MnSO 4 ·H 2 O and 0.228g (NH 4 ) 2 S 2 o 8 Dissolve in 100 ml of distilled water and add KOH dropwise to adjust the pH to 7. A solid was obtained by allowing the reaction to take place by hydrothermal method in an oven at a temperature of 130° C. for 10 hours, followed by precipitation. The obtained product was washed several times with distilled water, and dried to obtain a solid material.

example 2

[0066] The same procedure as that of Example 1 was performed except that the pH was adjusted to 9 by adding KOH.

example 3

[0068] The same procedure as that of Example 1 was performed except that the pH was adjusted to 9.2 by adding KOH.

Abstract

Provided are a manganese oxide nanowire, specifically, a manganese oxide nanowire having an aspect ratio of 20 or more, which can be widely used in various fields, including batteries, oxygen generators, and redox catalysts, a rechargeable battery including the manganese oxide nanowire, and a method of producing manganese oxide. Since the manganese oxide nanowire having a large aspect ratio has an increased specific surface area, it can be effectively used in various fields. In addition, various kinds of manganese oxide nanowires can be simply manufactured.

Description

technical field [0001] The present invention relates to a manganese oxide nanowire (especially a manganese oxide nanowire having an aspect ratio of 20 or greater), a rechargeable battery comprising the manganese oxide nanowire and a method for manufacturing the manganese oxide nanowire. nanowire method. More specifically, the present invention relates to a manganese oxide having an aspect ratio of 20 or more that can be effectively used in various fields including batteries, oxygen generators, and redox catalysts due to its increased specific surface area. Object nanowires, a rechargeable battery including the manganese oxide nanowires, and a method of manufacturing manganese oxides by which various types of manganese oxide nanowires can be easily manufactured in a simplified manner. Background technique [0002] Energy storage technology is gradually attracting attention as the market for cellular phones, notebook computers, electric vehicles, etc. rises. [0003] Therefo...
