“…By further introducing the multiscale strategy into the design of rGO/MXene aerogel, Cheng et al prepared a flexible and self-healing Zn-ion battery. [181] The in-plane nanopores generated by the chemical oxidation with hydrogen peroxide (H 2 O 2 ) solution offered extra ion channels, while the microscale pores formed by the gas foaming technique with hydrazine hydrate (N 2 H 4 ) supplied sufficient ionic active sites and electron channels. The Zn battery based on multiscale MXene aerogel presented an excellent energy density of 156.8 μWh cm −2 and the wearable promising.…”

Since the initial discovery of Ti3C2 a decade ago, there has been a significant surge of interest in 2D MXenes and MXene‐based composites. This can be attributed to the remarkable intrinsic properties exhibited by MXenes, including metallic conductivity, abundant functional groups, unique layered microstructure, and the ability to control interlayer spacing. These properties contribute to the exceptional electrical and mechanical performance of MXenes, rendering them highly suitable for implementation as candidate materials in flexible and wearable energy storage devices. Recently, a substantial number of novel research has been dedicated to exploring MXene‐based flexible materials with diverse functionalities and specifically designed structures, aiming to enhance the efficiency of energy storage systems. In this review, a comprehensive overview of the synthesis and fabrication strategies employed in the development of these diverse MXene‐based materials is provided. Furthermore, an in‐depth analysis of the energy storage applications exhibited by these innovative flexible materials, encompassing supercapacitors, Li‐ion batteries, Li–S batteries, and other potential avenues, is conducted. In addition to presenting the current state of the field, the challenges encountered in the implementation of MXene‐based flexible materials are also highlighted and insights are provided into future research directions and prospects.

“…Moreover, the water molecules act as a plasticizer to regulate the mechanical performance of the system as well as influence the conductivity of the material. [6][7][8][9] Although ionotronics are available in various forms, including membranes, [10,11] gels, and foams, [12] ionotronic fibers (IFs) are the most amenable for applications in wearable devices, such as sensors [13,14] and flexible optoelectronic displays. [15,16] In general, these devices require deformable, stretchable, and resilient materials that can be easily incorporated into other flat or textured wearable fabric platforms.…”

Innovation in the ionotronics field has significantly accelerated the development of ultraflexible devices and machines. However, it is still challenging to develop efficient ionotronic‐based fibers with necessary stretchability, resilience, and conductivity due to inherent conflict in producing spinning dopes with both high polymer and ion concentrations and low viscosities. Inspired by the liquid crystalline spinning of animal silk, this study circumvents the inherent tradeoff in other spinning methods by dry spinning a nematic silk microfibril dope solution. The liquid crystalline texture allows the spinning dope to flow through the spinneret and form free‐standing fibers under minimal external forces. The resultant silk‐sourced ionotronic fibers (SSIFs) are highly stretchable, tough, resilient, and fatigue‐resistant. These mechanical advantages ensure a rapid and recoverable electromechanical response of SSIFs to kinematic deformations. Further, the incorporation of SSIFs into core–shell triboelectric nanogenerator fibers provides outstanding stable and sensitive triboelectric response to precisely and sensitively perceive small pressures. Moreover, by implementing a combination of machine learning and Internet of Things techniques, the SSIFs can sort objects made of different materials. With these structural, processing, performance, and functional merits, the SSIFs prepared herein are expected to be applied in human–machine interfaces.
