A Ti₃C₂T_x MXene cathode and redox-active electrolyte based flexible Zn-ion microsupercapacitor for integrated pressure sensing application

Abstract

Frequently-used aqueous electrolytes in MXene based Zn-ion hybrid microsupercapacitors (MSCs) limit their cycling and rate stability. The metal and nonmetal additives in electrolytes for the performance improvement of Zn-ion MSCs...

MXene-Based Micro-Supercapacitors: Ink Rheology, Microelectrode Design and Integrated System

“…The MSCs provided stable energy for the pressure sensor, achieving a fast and stable response to different mass loads. Reprinted with permission from ref [64]. Copyright 2023 RSC.…”

“…In a similar study, Liu et al designed the in-plane integration of an MXene-based Znion micro-supercapacitor with a Ti 3 C 2 T x −DMF@P(VDF− TrFE) pressure sensor (Figure 16d). 64 By adding K 3 Co(CN) 6 to the Zn(CF 3 SO 3 ) 2 electrolyte, the rate performance and cycling stability of Zn-ion hybrid MSCs were considerably improved. The stable energy source provided stable energy for the pressure sensor, achieving a fast and stable response to different mass loads.…”

“…It requires compatible manufacturing and functional matching between MXene MSCs and other functional devices. Currently, MXene MSCs have been successfully integrated with nanogenerators, solar cells, sensors, filter circuits, and more. − During the integration process, a rational design of series-parallel integration between MSCs and matching of parameters such as voltage, current, and power between MSCs and other components is essential.…”

MXene based flexible photodetectors: progress, challenges, and opportunities

“…The spray coating techniques are simple and cost-effective ways to fabricate patterned films, especially, to prepare the Ti 3 C 2 T x MXene film because of its high concentration in water-based solvent and excellent hydrophilic properties. Our group proposed a self-powered flexible photodetector using Ti 3 C 2 T x MXene materials via the spray coating method, 54 as shown in Fig. 5a.…”

“…Section 2 mainly covers the surface engineering of MXenes, including their intrinsic metallic conductivity and strategies toward semiconductive MXenes. 50,51 And then, fabrication procedures for MXene electronics are introduced, for example, photolithography, 52 laser direct writing, 53 spray coating, 54 filtration, 55 etc. In Section 4, we focus on promising optoelectronic devices based on MXenes.…”
