Abstract

A kind of smart and flexible SCs based on MXene-based textile have been fabricated by a “dipping and drying” method.

Enhancing Capacitance Performance of Ti3C2Tx MXene as Electrode Materials of Supercapacitor: From Controlled Preparation to Composite Structure Construction

“…To date, large number of researches have used electrostatic self-assembly or hydrogen bonding to combine CPs with Ti 3 C 2 T x to form a layered alternating sandwich structure [16,98,99]. The single-layer hydrated intercalation changes the content of functional groups on the surface of Ti 3 C 2 T x , reducing -F, -OH, and interlayer water [100].…”

“…The positively charged MnO 2 nanosheet and the negatively charged Ti 3 C 2 T x form a composite film by electrostatic self-assembly, and the electrostatic attraction makes a close relationship between the two materials and enhances the interface electron conduction capability [ 98 ]. The self-assembled structure inhibits the phenomenon of Ti 3 C 2 T x stacking, which is beneficial to the diffusion of ions.…”

Enhanced Electrochemical Performance of Co2NiO4/Ti3C2Tx Structures through Coupled Synergistic Effects

“…After 10000 cycles at 10 A g −1 , hybrid electrodes still keep 83.4% of initial capacitance (Figure i), demonstrating the excellent cycling stability. Table shows a comparison of electrochemical performance between hybrid materials and some other electrodes …”

Progress of Two‐Dimensional Ti3C2Tx in Supercapacitors

“…Compared with electrically neutral PVA, inserting a conductive polymer with intrinsic highly redox‐active behavior and good conductivity, such as PPy, PANI, and PEDOT, between the Ti 3 C 2 T x layers can provide conductive, aligned paths for charge percolation and increase pseudocapacitance . Boota et al.…”

“…Compared with electrically neutralP VA,i nserting ac onductive polymer with intrinsic highly redox-active behavior and good conductivity,s uch as PPy,P ANI, and PEDOT,b etween the Ti 3 C 2 T x layers can provide conductive, aligned paths for charge percolation and increase pseudocapacitance. [71,[90][91][92][93][94][95][96][97] Boota et al demonstrated simultaneous intercalation, alignment, and oxidant-free polymerization of pyrrole on Ti 3 C 2 T x (Figure 15 a). [90] With the combination of hydrogen bondingf rom the pyrrole ring and functional groups of oxygen or fluorine on the Ti 3 C 2 T x surface, the polymerized chains align and promote the preferential growth of PPy in two dimensions rather than randomly.…”
