There is an increasing demand of low cost, flexible, stable, and environmentally benign power sources for emerging wearable electronic equipment. Herein, we develop high performance psudo-su- percapacitor electrodes based on nano Mn02 de- posited on a carbon textile, which was made fromcotton cloth by carbonization in Ar gas, served as 3D flexible scaffolds as shown in Fig. 1. The MnO2 nanostructures were realized via a simple in situ re- dox replacement reaction between potassium per- manganate and the carbonized cloth.
