Abstract

original image

Bendy electrodes: A simple and efficient route for the growth of branched MnO2 nanorods on a flexible substrate at ambient temperature without templates is reported. The capacitive characteristics of the MnO2 nanorods presented here can be applied to produce inexpensive and high-performance flexible supercapacitors on a large scale. Practical demonstration could show technological interest for the design of flexible electrodes in the industry.
