Intelligent electronics are drawing vast attention with an enormous market and revolutionizing the daily lives of humans in extensive fields. Fiber-shaped batteries (FSBs), which act as the core component of wearable electronics, demonstrate superior flexibility, wearability, mechanical stresses, adaptability to deformation, and scale production with a unique one-dimensional architecture. However, many difficulties, including a complicated fabrication process, high internal resistance, and poor stability, hindered its development. Herein, we first summarized the influence factors between different fabrication strategies and device configurations. Subsequently, we overviewed recent achievements and performances by categorizing the investigation of FSBs, for example, lithium-ion batteries, aqueous zinc-ion batteries, and metal–air batteries. In the end, technical challenges and perspectives in practical wearable applications are also discussed to promote the boosting of this fascinating field. In this review, a focused analysis of the recent advancements in FSBs is summarized, and we take a closer look at the boosted development of FSBs from mere potential industrialization to a genuinely new era.

Lithium-ion batteries (LIBs) are complex electrochemical systems whose performance is determined by the proper design and optimization of its individual components, such as active materials, separators, polymer binders, electrolytes and conductive additives. In the quest for high-energy and high-power density batteries and next-generation ultrahigh-capacity battery electrodes, industry and academia have worked hand-in-hand over the last few decades, developing strategies for improving the performance of each component in an LIB. However, only recently has the development of multifunctional polymer binders become a focus, with the goal of providing additional functionality beyond simple mechanical adhesion. Polymer binders, exemplified by poly(vinylidene fluoride) (PVDF), are typically an inactive component in a composite electrode that does not contribute to capacity. Moreover, limited binding strength, poor mechanical properties and the absence of electronic and ionic conductivity make PVDF inadequate for application in emerging high-capacity and highpower density batteries. In this regard, conjugated polymers have gained attention as conductive polymer binders and/or coatings for the cathodes and anodes in LIBs. The ability of conjugated polymers to transport both electronic and ionic charge carriers endows them with mixed electron and Li + ion transporting properties in an LIB. Based on the enormous potential of conjugated polymer binders to enhance the performance of LIBs, in this review, we present an overview of conducting polymer binders/coatings and their chemical design strategies, developed in the last decade, for use in LIBs.

“…Better electrochemical behavior is achieved by SA’s enhanced stickiness, which increases adhesion strength with the current collector. SA additionally provides a protective coating that reduces the direct electrode–electrolyte interaction . The LNMO half-cells containing the Xylan-SA binder demonstrated significantly better cycling qualities (capacity retention of 99.8% after 450 cycles at 1 C ), rate capabilities, and good mechanical properties even for a relatively high active mass loading (6.2 mg cm –2 ).…”

LiNi 0.5 Mn 1.5 O 4 (LNMO) with a spinel structure is one of the most promising cathode materials choices for Li-ion batteries (LIBs). However, at a high operating voltages, the decomposition of organic electrolytes and the dissolution of transition metals, especially Mn(II) ions, cause unsatisfactory cycle stability. The initial application of a sodium alginate (SA)-xylan biopolymer as an aqueous binder aims to address the aforementioned problems. The SX28-LNMO electrode has a sizable discharge capacity, exceptional rate capability, and long-term cyclability with a capacity retention of 99.8% after 450 cycles at 1C and a remarkable rate capability of 121 mAh g −1 even at 10C. A more thorough investigation illustrated that SX28 binder provides a substantial adhesion property and generates a uniform (CEI) layer on the LNMO surface, suppressing electrolytes' oxidative decomposition upon cycling and improving LIB performances. This work highlights the potential of hemicellulose as an aqueous binder for 5.0 V high-voltage cathodes.
