“…The linear capacitances ( C L ) and areal capacitances ( C A ) were calculated as well (Figure e). The values of C L and C A are 1740 μF cm −1 and 18.51 mF cm −2 at the current of 0.02 mA, which are remarkable when comparing to the previous results, as shown in Table S2 of the Supporting Information . Notably, its capacitance retention was about 73% when the charging/discharging current increased from 0.02 to 0.10 mA, showing excellent rate capability.…”

“…Therefore, the fabrication of fibrous energy devices has attracted enormous attentions recently . However, so far the performances of fiber‐shaped energy devices, such as DSSCs (Table S1, Supporting Information) and supercapacitors (Table S2, Supporting Information) are still lower than the corresponding planar devices, because it is difficult to find appropriate fibrous electrodes with high electrochemical activity and stability.…”

Here an all-purpose fibrous electrode based on MoS 2 is demonstrated, which can be employed for versatile energy harvesting and storage applications. In this coaxial electrode, ultrathin MoS 2 nanofilms are grown on TiO 2 nanoparticles coated carbon fiber. The high electrochemical activity of MoS 2 and good conductivity of carbon fiber synergistically lead to the remarkable performances of this novel composite electrode in fibrous dye-sensitized solar cells (showing a record-breaking conversion efficiency of 9.5%) and high-capacity fibrous supercapacitors. Furthermore, a self-powering energy fiber is fabricated by combining a fibrous dye-sensitized solar cell and a fibrous supercapacitor into a single device, showing very fast charging capability (charging in 7 s under AM1.5G solar illumination) and an overall photochemical-electricity energy conversion efficiency as high as 1.8%. In addition, this wire-shaped electrode can also be used for fibrous Li-ion batteries and electrocatalytic hydrogen evolution reactions. These applications indicate that the MoS 2based all-purpose fibrous electrode has great potential for the construction of high-performance flexible and wearable energy devices.

A simple approach for growing porous electrochemically reduced graphene oxide (pErGO) networks on copper wire, modified with galvanostatically deposited copper foam is demonstrated. The as-prepared pErGO networks on the copper wire are directly used to fabricate solid-state supercapacitor. The pErGO-based supercapacitor can deliver a specific capacitance (Csp) as high as 81±3 F g−1 at 0.5 A g−1 with polyvinyl alcohol/H3PO4 gel electrolyte. The Csp per unit length and area are calculated as 40.5 mF cm−1 and 283.5 mF cm−2, respectively. The shape of the voltammogram retained up to high scan rate of 100 V s−1. The pErGO-based supercapacitor device exhibits noticeably high charge-discharge cycling stability, with 94.5% Csp retained even after 5000 cycles at 5 A g−1. Nominal change in the specific capacitance, as well as the shape of the voltammogram, is observed at different bending angles of the device even after 5000 cycles. The highest energy density of 11.25 W h kg−1 and the highest power density of 5 kW kg−1 are also achieved with this device. The wire-based supercapacitor is scalable and highly flexible, which can be assembled with/without a flexible substrate in different geometries and bending angles for illustrating promising use in smart textile and wearable device.

“…SCs with metal oxide electrodes are usually classified as pseudocapacitors . The energy storage of pseudocapacitors comes from the electron transfer during the fast reversible redox reaction of electro‐active species on the surface of the electro‐active materials, resulting in much higher capacitance and energy density of the pseudocapacitors than the EDLCs with carbon‐based electrodes …”

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...
