“…Many conducting polymers can achieve high capacitance in acidic electrolytes, so do the MXene/conducting polymer composites. Nowadays, many kinds of conducting polymers, such as polyaniline (PANI) [228] , poly(3,4 ethylenedioxythiophene) (PEDOT) [ 229 , 230 ], polypyrrole (PPy) [231] , polymeric dopamine (PDA) [232] and polyfluorene derivatives (PFDs) [233] , have been combined with MXenes to yield hybrids with excellent electrochemical performances.…”

MXene Electrochemkal capacitor Electrode materials MXene-based composites DevicesMXenes, a family of 20 transition metal carbides/nitrides with a general formula of M.+t X,, T x (n=l ~3), show promising potential for energy storage applications owing to their 20 lamellar structure, impressive density, metallic-liloe conductivity, tunable terminations and intercalation pseudocapacitance charge storage mechanism. Various combinations of transition metals, C and/or N, as well as different n layers result in a broad range of MXenes, but only about a small number have been prepared and used for capacitive energy storage applications (supercapacitors) so far, with Ti 3 Ci T x being the most studied one. This review summarizes the recent advances, achievements and challenges of MXenes for supercapacitors. The preparation methods, composition versatility, material and electrode architectures, chemical modification and hybridization with other active materials ofMX enes are presented. Moreover, the electrochemical characterizations and energy storage mechanisms of MXenes in aqueous and non-aqueous electrolytes are discussed, as well as the preparation of flexible and printable MXene based electrodes and devices. Flnally, perspective is also given, providing guidance for the future development of MXenes with advanced performances for designing the next generation of supercapacitors.

The increasing demand for high‐performance rechargeable energy storage systems has stimulated the exploration of advanced electrode materials. MXenes are a class of two‐dimensional (2D) inorganic transition metal carbides/nitrides, which are promising candidates in electrodes. The layered structure facilitates ion insertion/extraction, which offers promising electrochemical characteristics for electrochemical energy storage. However, the low capacity accompanied by sluggish electrochemical kinetics of electrodes as well as interlayer restacking and collapse significantly impede their practical applications. Recently, interlayer space engineering of MXenes by different chemical strategies have been widely investigated in designing functional materials for various applications. In this review, an overview of the most recent progress of 2D MXenes engineering by intercalation, surface modification as well as heterostructures design is provided. Moreover, some critical challenges in future research on MXene‐based electrodes have been also proposed.
