Our modern and technological society requests enhanced energy storage devices to tackle the current necessities. In addition, wearable electronic devices are being demanding because they offer many facilities to the person wearing it. In this manuscript, a historical review is made about the available energy storage devices focusing on super-capacitors and lithium-ion batteries, since they currently are the most present in the industry, and the possible polymeric materials suitable on wearable energy storage devices. Polymers are a suitable option because they not only possess remarkable mechanical resistance, flexibility, long life-times, easy manufacturing techniques and low cost in addition to they can be environmentally friendly, nontoxic, and even biodegradable too. Moreover, the electrical and electrochemical polymer properties can be tunning with suitable fillers giving to versatile conducting polymer composites with a good cost and properties' ratio. Although the advances are promising, there are still many drawbacks that need to be overcome. Future research should focus on improving both the performance of materials and their processability on an industrial scale, where additive manufacturing offers many possibilities. The sustainability of new energy storage devices should not

“…For wearable e-textile applications, LIBs must be flexible and stretchable for comfortable wearing and must also maintain stable battery performance under deformation. Research on e-textile LIBs has focused on the development of e-textile LIB electrodes, typically by depositing a slurry of electroactive materials onto a conductive fabric, which acts as a current collector. ,− The stretchability of these electrodes is limited by the intrinsically brittle nature of the electroactive material, which is vulnerable to cracking or delamination with mechanical deformation. To solve this mechanical mismatch, we used the textile-centric design approach to protect brittle electroactive materials from strain .…”

Conspectus Electronics worn on the body have the potential to improve human health and the quality of life by monitoring vital signs and movements, displaying information, providing self-illumination for safety, and even providing new routes for personal expression through fashion. Textiles are a part of daily life in clothing, making them an ideal platform for wearable electronics. The acceptance of wearable e-textiles hinges on maintaining the properties of textiles that make them compatible with the human body. Beneficial properties such as softness, stretchability, drapability, and breathability come from the 3D fibrous structures of knitted and woven textiles. However, these structures also present considerable challenges for the fabrication of wearable e-textiles. Fabrication methods used for modern electronic devices are designed for 2D planar substrates and are mostly unsuitable for the complex 3D structures of textiles. There is thus an urgent need to develop fabrication methods specifically for e-textiles to advance wearable electronics. Solution-based fabrication methods are a promising approach to fabricating wearable e-textiles, especially considering that textiles have been successfully modified using pigmented dyes in dyebaths and printing inks for thousands of years. In this Account, we discuss our research on the solution-based electroless metallization of textiles to fabricate conductive e-textiles that are building blocks for e-textile devices. Electroless metallization solutions fully permeate textile structures to deposit metallic coatings on the surfaces of individual textile fibers, maintaining the inherent textile structures and wearability. The resulting e-textiles are highly conductive, soft, and stretchable. We furthermore discuss ways to turn the challenges related to textile structures into new opportunities by strategically using the structural features of textiles for e-textile device design. We demonstrate this textile-centric approach to designing e-textile devices using two examples. We discuss how the structure of an ultrasheer knitted textile forms a useful framework for new e-textile transparent conductive electrodes and describe the implementation of these electrodes to form highly stretchable light-emitting e-textiles. We also show how the structural features of velour fabrics form the basis for an innovative “island-bridge” strain-engineering structure that enables the integration of brittle electroactive materials and protects them from strain-induced damage, leading to the fabrication of stretchable textile-based lithium-ion battery electrodes. With the vast variety of textile structures available, we highlight the opportunities associated with this textile-centric design approach to advance textile-based wearable electronics. Such advances depend on a deep understanding of the relationship between the textile structure and the device requirements, which may potentially lead to the development of new textile structures customized to support specific devices. We conclude w...

“…These different textile architectures have the potential to form the basis for architectural strain-engineering approaches that enable the integration of brittle functional materials with soft textiles to solve the mechanical mismatch problem. Although previous research has used textiles as substrates for LIBs, − no reports have yet emerged that use textile structures as an architectural strain-engineering strategy. Most of the research on developing textile-based LIBs for wearable power sources has used flexible fabrics as substrates to form electrodes, such as woven carbon cloth, − woven cotton fabrics, woven polyester fabrics, and nonwoven polyester fabrics. , These textile-based LIB electrodes exhibit excellent electrochemical performance and mechanical flexibility but lack softness and stretchability.…”

“…Although the softness and stretchability of knitted textiles make them a more suitable choice for wearable electronics, the integration of functional LIB materials with knitted structures has proven to be difficult. For example, Ghadi et al reported LIB electrodes by casting a LiCoO 2 slurry onto a stretchable knitted silver fabric . The slurry filled in the fabric voids, stiffening the fabric and rendering the composite vulnerable to cracking.…”

The advancement of wearable electronics depends on the seamless integration of lightweight and stretchable energy storage devices with textiles. Integrating brittle energy storage materials with soft and stretchable textiles, however, presents a challenging mechanical mismatch. It is critical to protect brittle energy storage materials from strain-induced damage and at the same time preserve the softness and stretchability of the functionalized e-textile. Here, we demonstrate the strategic use of a warp-knitted velour fabric in an “island-bridge” architectural strain-engineering design to prepare stretchable textile-based lithium-ion battery (LIB) electrodes. The velour fabric consists of a warp-knitted framework and a cut pile. We integrate the LIB electrode into this fabric by solution-based metallization to create the warp-knitted framework current collector “bridges” followed by selective deposition of the brittle electroactive material CuS on the cut pile “islands”. As the textile electrode is stretched, the warp-knitted framework current collector elongates, while the electroactive cut pile fibers simply ride along at their anchor points on the framework, protecting the brittle CuS coating from strain and subsequent damage. The textile-based stretchable LIB electrode exhibited excellent electrical and electrochemical performance with a current collector sheet resistance of 0.85 ± 0.06 Ω/sq and a specific capacity of 400 mAh/g at 0.5 C for 300 charging–discharging cycles as well as outstanding rate capability. The electrical performance and charge–discharge cycling stability of the electrode persisted even after 1000 repetitive stretching–releasing cycles, demonstrating the protective functionality of the textile-based island-bridge architectural strain-engineering design.
