Supercapacitor Electrodes: A Layer‐by‐Layer Assembly Route to Electroplated Fibril‐Based 3D Porous Current Collectors for Energy Storage Devices (Small 19/2021)

Abstract

Highly flexible and porous metallic papers with bulk metallic conductivity and large surface areas are prepared using a metal nanoparticle (NP) assembly‐induced electroplating approach by Seung Woo Lee, Jinhan Cho, and co‐workers in article number 2007579. High‐energy pseudocapacitive NPs and conductive metal NPs are also layer‐by‐layer‐assembled onto the 3D porous metallic paper, which significantly increases the areal capacitance of metallic paper‐based supercapacitor electrode.
