Recent Advances in Layered Ti 3 C 2 T x MXene for Electrochemical Energy Storage

摘要: Ti3 C2 Tx , a typical representative among the emerging family of 2D layered transition metal carbides and/or nitrides referred to as MXenes, has exhibited multiple advantages including metallic conductivity, plastic layer structure, small band gaps, and hydrophilic nature its functionalized surface. As result, this material is intensively investigated for application in energy storage field. The composition, morphology texture, surface chemistry, structural configuration directly influence electrochemical performance, e.g., use well-designed rechargeable battery anode significantly enhanced performance by providing more chemically active interfaces, shortened ion-diffusion lengths, improved in-plane carrier/charge-transport kinetics. Some recent progresses MXene are achieved storage. This Review summarizes advances synthesis applications supercapacitors, lithium-ion batteries, sodium-ion lithium-sulfur batteries. current opportunities future challenges addressed energy-storage devices. seeks provide rational in-depth understanding relation between nanostructural/chemical composition which will promote further development MXenes applications.
