Abstract

The present invention provides a method for making an electrode. Firstly, a conducting substrate is provided. Secondly, a plurality of nano-sized structures is formed on the conducting substrate by a nano-imprinting method. Thirdly, a coating is formed on the nano-sized structures. The nano-sized structures are configured for increasing specific surface area of the electrode.
