A review of graphene assembled films as platforms for electrochemical reactions
Source abstract
Abstract
: Because of their low electrical conductivity, sluggish ion diffusion, and poor stability, conventional electrode materials are not able to meet the growing demands of energy storage and portable devices. Graphene assembled films (GAFs) formed from graphene nanosheets have an ultrahigh conductivity, a unique 2D network structure, and exceptional mechanical strength, which give them the potential to solve these problems. However, a systematic understanding of GAFs as an advanced electrode material is lacking. This review focuses on the use of GAFs in electrochemistry, providing a comprehensive analysis of their synthesis methods, surface/structural characteristics, and physical properties, and thus understand their structure-property relationships. Their advantages in batteries, supercapacitors, and electrochemical sensors are systematically evaluated, with an emphasis on their excellent electrical conductivity, ion transport kinetics, and interfacial stability. The existing problems in these devices, such as chemical inertness and mechanical brittleness, are discussed and potential solutions are proposed, including defect engineering and hybrid structures. This review should deepen our mechanistic understanding of the use of GAFs in electrochemical systems and provide actionable strategies for developing stable, high-performance electrode materials.
