Shearing induced ordered structures in two-dimensional nanomaterials-based electrodes for boosted pseudocapacitive kinetics

Abstract

Two-dimensional (2D) nanomaterials have been extensively pursued as functional electrodes in electrochemical energy storage devices. Numerous efforts have been devoted to improving the electrochemical performance by engineering the chemical composition and structure of 2D nanomaterials, while little attention was paid to optimizing their electrode manufacturing by wet processing techniques. Herein, we study how the shear processing impacts the electrochemical performance of 2D nanomaterial-based electrodes using graphene oxide/polyaniline (GO/PANI) colloidal hydrogels as a model electrode slurry. The GO/PANI hydrogels are processed into reduced GO/PANI (RGO/PANI) membranes by blade casting f..
