The existing fiber-shaped energy storage devices include the supercapacitor, [15] the lithium (Li)-ion battery, [16] the lithium-sulfur battery, [17] the lithium-air battery, [18] the zinc-air battery, [19] the aluminum-air battery, [20] the sodiumion battery, [21] the zinc-ion battery, [22] and the silver-zinc battery. [23] Among them, the supercapacitor has been reported mostly due to the easy fabrication, and lithium-ion battery has laid the foundation for the development of other fiber-shaped batteries, which are thus discussed mainly in this review. 3) Light-emitting devices have been developed for various applications such as display, illumination, and photo therapy. According to the working mechanisms, there are electroluminescence, [24] mechanoluminescence, [25] photoluminescence, [26] thermoluminescence, [27] sonoluminescence, [28] and chemiluminescence. [29] Among these, fiber-shaped electroluminescent devices have been developed extensively due to their good controllability, driven by direct current (DC) [30] or alternating current (AC) [31] electrical method, which are expounded mainly later. 4) Fibershaped sensors have found great potentials in the field of wearable medical devices for fitness monitoring and medical diagnostics especially as aging populations grow. By virtue of the 1D structure, fiber-shaped sensors can be implanted into the body with little injure or they can detect multiple signals simultaneously after integration into a tiny unit. [32] Fiber-shaped sensors generally work via physical processes on the basis of conducting fiber [33] and optical fiber, [34] and chemical processes based on chemical ligand. [35] Thereinto, fiber optic sensors have already been used in petrochemical, electric power, medical, civil engineering, etc. The detailed discussions about the above three fiber-shaped sensors are presented in the later section.Despite the great progress made in fiber and textile electronics, we have to realize that most of the research results are far from practical applications due to several existing obstacles. The performances of fiber-shaped electronic devices are not good enough to attract investors. For instance, although fiber-shaped solar cells have achieved a record power conversion efficiency (PCE) of 10%, [36] this value falls far below the certified efficiency of 24.2% for planar solar cells. [37] Besides, fiber-shaped electronic devices often decay in performance further as their lengths increase. Apart from low performances, scalable fabrication is another hard nut to crack if fiber-shaped electronic devices are to be commercialized. For one thing, researchers usually can only realize fiber-shaped electronic devices with the lengths from several to hundreds of millimeters at present owing to the absence of appropr...

electronic devices built on planar substrates, textile electronic devices can be integrated into different materials that fit the curved surface of the human body or other nonplanar surfaces. Besides, it can bear deformations in almost all dimensions, making it applicable for long-term usage as minimal disruption can be made on the comfort and daily activities of the wearers. Another attractive feature of textile electronic devices is that, in principle, they are compatible to the conventional textile technology and can be manufactured on a large scale using the textile manufacturing technique, such as the rollto-roll process.Inspired by the exciting potential applications of textile electronic devices in healthcare, communications, environments, sports, security, and so on, in the past several years, many kinds of textile electronic devices have been produced by researchers all over the world, including sensors, solar cells, thermoelectric power generators and nanogenerators, diodes, transistors, circuits, etc. Ideally, these textile electronic devices would be directly woven into cloth and worn on human body for daily usage. As a result, these devices should be of lightweight, stable performance, and can bear deformations for long-term usage.Flexible textile electronic devices require flexible textile/fiber energy storage devices as compatible power suppliers. To match flexible textile electronic devices, the energy storage devices should have similar textile/fiber shapes with excellent flexibility, mechanical stability, light weight and can also bear deformations in all dimensions. Mainly two types of textile/fiber energy storage devices are explored including fiber lithium-ion batteries (LIBs) and fiber supercapacitors (SCs). [27][28][29][30][31][32][33][34][35][36][37][38][39][40] In recent years, LIBs were successfully made into fiber shapes to fit for flexible textile electronic devices. [41] Unfortunately, relatively complicated procedures are needed to fabricate fiber LIBs. Besides, the power densities of fiber LIBs are still quite low for practical applications. Compared with LIBs, supercapacitors offer higher power delivery capability, faster charge/discharge rates, long cycle livers, and bridging functions for the power-energy gap between traditions dielectric capacitors and batteries. These features make SCs ideal power suppliers for wearable and textile electronics.Over the past decades, researches on fiber SCs expanded very fast and great progresses have been achieved. Although several reviews focusing on some special aspects of fiber SCs Fiber supercapacitors (SCs), with their small size and weight, excellent flexibility and deformability, and high capacitance and power density, are recognized as one of the most robust power supplies available for wearable electronics. They can be woven into breathable textiles or integrated into different functional materials to fit curved surfaces for use in day-to-day life. A comprehensive review on recent important development and progress in fiber SCs is pro...

“…Typically, functional materials/components can be directly introduced into fiber electrodes to form functional supercapacitor fibers. [30] Modifying common elastic fiber substrate with functional layer was also effective to construct functional fiber-shaped supercapacitors with responsive behavior [31,32] (i.e., shape-memory and self-healing) and stable electrochemical performance (Figure 3d,e). [30] Under the premise of a stable electrochemical performance, the fluorescent component introduced fluorescent indication capability to the fiber, which was particularly promising for flexible and wearable devices applied in dark environment (Figure 3b,c).…”

Wearable electronic devices that can be directly worn on the human body or combined with daily textiles have experienced a booming development with the rapid development of mobile electronics. These wearable electronic devices strongly demand indispensable, high performance power systems with small size, high flexibility, and adaptability to comfort frequent deformations during usage. Fabricating high-performance energy storage systems in a 1D shape like fiber is recognized as a promising strategy to address the above issues. These fiber-shaped power systems with diameters from tens to hundreds of micrometers can adapt to various deformations for stable operation in close contact with the human body. It is also possible to further weave such 1D energy storage devices into breathable textiles with matching electrochemical performances for the wearable electronics. Here, the key advancements related to fiber-shaped energy storage devices are reviewed, including the synthesis of materials, the design of structures, and the optimization of properties for the most explored energy storage devices, i.e., supercapacitors, aprotic lithium-based batteries, as well as novel aqueous battery systems. The remaining challenges are finally discussed to highlight the future direction of the development of fiber-shaped energy storage devices. www.advelectronicmat.de harvesting in the 1D format is then highlighted. The remaining challenges in fiber-shaped energy storage devices are finally discussed to provide insights for the future development.
