Pivotal Role of the Granularity Uniformity of the WO₃ Film Electrode upon the Cyclic Stability during Cation Insertion/Extraction.

ABSTRACT: Delicate design and precise manipulation of electrode morphology has always been crucial in electrochemistry. Generally, porous morphology has been preferred due to the fast kinetic transport characteristics of cations. Nevertheless, more refined design details such as the granularity uniformity that usually goes along with the porosity regulation of film electrodes should be taken into consideration, especially in long-term cation insertion and extraction. Here, inorganic electrochromism as a special member of the electrochemical family and WO₃ films as the most mature electrochromic electrode material were chosen as the research background. Two kinds of WO₃ films were prepared by magnetron sputtering, one with a relatively loose morphology accompanied by nonuniform
