“…Fiber‐shaped supercapacitors (FSCs) are receiving significant attention in the literature for use in powering portable and wearable electronics . FSCs are attractive for wearable applications because they can be integrated into textiles or be made elastic if the fiber electrodes are resilient to bending, stretching, and twisting . To power electronics, FSCs require high electrical conductivity and high energy storage performance from the fiber electrodes.…”

applications because they can be integrated into textiles or be made elastic if the fiber electrodes are resilient to bending, stretching, and twisting. [7][8][9][10][11][12] To power electronics, FSCs require high electrical conductivity and high energy storage performance from the fiber electrodes. In hybrid fiber electrodes that comprise of at least one active material and a binder, these electrode properties are dependent upon the amount of active material (loading) and how well the two components are mixed. It is also important that the method of production can be made scalable and continuous. To date, however, a continuous and scalable production of fiber electrodes with high electrical conductivity and energy storage performance remains a challenge. One example of fiber fabrication is via a deposition technique that involves coating of active materials onto a conductive fiber substrate. [13][14][15][16][17][18] This method is simple and scalable to achieve FSC electrodes with active material loading of up to ≈30 wt%. [13,14] Another fiber fabrication example is biscrolling technique, which can trap active materials onto the helical corridors of carbon nanotube (CNT) sheets. [19][20][21][22][23][24][25] This method is suitable for making tens of centimeters long fiber electrodes with very high active material loadings (>90 wt%). Wet-spinning is an industrially viable approach to fiber production and has therefore attracted considerable attention for the fabrication of various FSC electrodes, such as graphene fibers, [26][27][28] CNT fibers, [29][30][31] and conducting polymer fibers. [32][33][34] In wet-spinning composite formulations containing an active material and a binder, the two components must be homogeneously dispersed to achieve "spinnablility" into long continuous fibers. Also, the two components must not limit the function of the other component particularly at high active material loading. The high conductivity and electrochemical performance of the active material must be maintained (for use as electrodes) and the binder must provide durability and flexibility (for continuous production).Ti 3 C 2 T x is one of the growing family of 2D early-transition metal carbides/carbonitrides (MXenes), which shows great promise for application in FSC electrodes. [14,35,36] Besides its high conductivity (up to 9880 S cm −1 ), [37] Ti 3 C 2 T x MXene has an exceptionally high capacitance (up to 1500 F cm −3 ) [38] that comes predominantly from the intercalation/deintercalation of H + and surface redox Fiber-shaped supercapacitors (FSCs) are promising energy storage solutions for powering miniaturized or wearable electronics. However, the scalable fabrication of fiber electrodes with high electrical conductivity and excellent energy storage performance for use in FSCs remains a challenge. Here, an easily scalable one-step wet-spinning approach is reported to fabricate highly conductive fibers using hybrid formulations of Ti 3 C 2 T x MXene nanosheets and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate....

Fiber-shaped supercapacitors have drawn much attention for their great potential application in future portable and wearable electronics because of their outstanding flexibility, tiny volume, and good deformability. In this work, commercial poly(ethylene terephthalate) (PET) thread was successfully converted into an electrically conductive and electrochemically active thread by introducing copper sulfide (CuS) and polyaniline (PANI) via simple chemical bath deposition and electrochemical deposition. The obtained PANI/CuS/PET electrode combined all the advantages of PET, CuS, and PANI, showing an excellent physical and electrochemical performance. The fiber-shaped supercapacitor exhibits a high specific capacitance of 29 mF cm −2 (116 mF cm −2 for a single electrode) and good cycling stability with 93.1% retention after 1000 cycles. With the simple preparation method and low-cost raw materials, this strategy provides a reference for the fabrication of portable/wearable energy storage devices.

The rapid development of wearable electronics has accelerated the development of wearable energy storage devices. Wearable supercapacitors have aroused widely interest due to their large power density. However, there are still many challenges in the practical application of wearable supercapacitors. This paper summarizes the structure, working mechanism, materials and key parameters of wearable supercapacitors. And we reviewed the challenges of wearable supercapacitors in practical applications, namely safety, mechanical adaptability, self‐charging capability, environmental tolerance, and multifunction. Finally, these challenges are summarized and prospected. We hope to inspire some work to solve the practical application challenges of wearable supercapacitors.
