Electrochemical Energy Storage: Direct Utilization of Photoinduced Charge Carriers to Promote Electrochemical Energy Storage (Small 21/2021)

Abstract

This cover image shows that the as-prepared light-sensitive electrode materials are composed of CF@CuOx@NiCuOx nanoarrays, which can promote the pseudocapacitive property by photoinduced charge carriers. In the image, the standing rods represent the individual CuOx@NiCuOx, and the h+/e− highlighted in the yellow sphere demonstrates the charge separation/transfer occurring within the NiCuOx nanostructures under light irradiation (presented in article number 2008047 by Ting Zhu, Quanbing Liu, Qingyu Yan, and co-workers).
