Application on Supercapacitor of Manangese Oxide Electrodes Prepared by Various Synthesis Methods

다양한 합성방법으로 제조된 망간옥사이드 전극들의 수퍼커패시터에 대한 응용

We describe the preparation of a manganese oxide polymorph in which the solid-pore architecture of the material is controllably varied. All MnO$_2$ gels derived from a KMnO$\_$4/-based sol-gel synthesis. The mesoporous structure of the initial gel is maintained by removingore fluid under conditions where the capillary forces that result fro extraction are either low or no existent. are either low or noexistent. Controlling both the pore and solid architecture on the nanoscale offers a strategy for the design of supercapacitor.
