About this Research Topic
With the rapid development of portable and wearable electronic products, flexible wearable energy storage devices have gradually become a hot research field. Among them, one-dimensional electrochemical energy storage fabrics, such as fiber-based supercapacitors and lithium-ion batteries, have become one of the most promising directions due to their portability, flexibility, wear resistance, knittability, mechanical and electrical machinability. Compared to bulk structures, two-dimensional (2D) materials have unique advantages in the research of novel fiber-based energy storage fabrics due to their High ion transport rate, good flexibility, rich active sites, high specific surface area and interlayer regulation properties. As a result, 2D transition metal carbides and nitrides (MXenes), transition metal oxides (TMOs), transition metal chalcogenides (TMDs), transition metal phosphides (TMPs), layered double hydroxides (LDHs), metal-organic framework materials (MOFs), conducting polymers, boron nitride and graphene-based carbon materials have witnessed rapid development in recent years.
Currently, despite a variety of parallel, twisted, and coaxial architectures based on 2D materials that have made great progress in fiber-shaped energy storage devices, most of the research results are far from practical applications due to several existing obstacles. In practical application, the fiber-based devices with no ink-binding mode, represented by in-situ growth, will encounter problems such as complex operation, unstable device structure and low loading. Although the ink-binding methods represented by the integrated preparation of coating or spinning could easily construct fiber-based devices, many factors have to be taken into account in dispersive inks made from different 2D materials. Additionally, the separation between the anode and anode is easy to occur when the device is bent, which could greatly reduce the ion transport rate and electrochemical performance. Besides, fiber-shaped devices often decay in performance further as their lengths increase. Apart from the performance impact, the scalable fabrication of 2D materials and their devices is another hard nut to crack if fiber-shaped devices are to be commercialized. Therefore, in this Research Topic, we welcome contributions that will stimulate the continuous studies on how to fabricate and construct different 2D materials and their device structures for fiber-based energy storage fabric.
