Substantial progress has been made in exploring the novel structures and sensing mechanisms for wearable sensors, where high sensitivity plays an essential role. For fiber‐based wearable sensors, the sensitivity mainly depends on the electroconductivity and surface microstructure of fibers. However, preparing highly conductive fibers along with excellent stretchability and long‐term stability via facile and effective approaches is still challenging. Therefore, in this work, wet‐spun poly (3, 4–ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) fibers with a superior conductivity of 105 S cm−1 and exceptional stretchability of 132% have been successfully achieved by adding urea and soluble copper salts into a coagulation bath. With the additional copper ions, the formation of a copper complex with fluff‐like arrays morphology occurs spontaneously on the surface of fibers, while the existence of urea not only enhances their electroconductivity and stretchability, but also endows both with long‐term stability. Meanwhile, the obtained fibers reveal fast response time and ultra‐low detection limit to the external stimuli, and braided fabrics decorated with such fibers own potential applications for wearable electronic textiles. More importantly, this work explores the significance of durability for PEDOT:PSS fiber‐based devices, inspiring a unique path for novel fiber design.

The realistic application of lithium-sulfur batteries (LSBs) as a competitive candidate for next-generation electrochemical energy storage systems is still hampered by the severe polysulfide shuttle effect and sluggish redox kinetics....

Al–S battery (ASB) is a promising energy storage device, notable for its safety, crustal abundance, and high theoretical energy density. However, its development faces challenges due to slow reaction kinetics and poor reversibility. The creation of a multifunctional cathode material that can both adsorb polysulfides and accelerate their conversion is key to advancing ASB. Herein, a composite composed of polyoxometalate nanohybridization‐derived Mo2C and N‐doped carbon nanotube‐interwoven polyhedrons (Co/Mo2C@NCNHP) is proposed for the first time as an electrochemical catalyst in the sulfur cathode. This composite improves the utilization and conductivity of sulfur within the cathode. DFT calculations and experimental results indicate that Co enables the chemisorption of polysulfides while Mo2C catalyzes the reduction reaction of long‐chain polysulfides. X‐ray photoelectron spectroscopy (XPS) and in situ UV analysis reveal the different intermediates of Al polysulfide species in Co/Mo2C@NCNHP during discharging/charging. As a cathode material for ASB, Co/Mo2C@NCNHP@S composite can deliver a discharge‐charge voltage hysteresis of 0.75 V with a specific capacity of 370 mAh g−1 after 200 cycles at 1A g−1.
