Carbon fibers (CFs) are ideal current collectors for ZIBs due to their good flexibility, electrical conductivity and corrosion resistance. Herein, a novel CFs-based current collector is proposed. At first, the inertness and non-polarity of CFs were significantly modified by activating and etching to obtain a multi-layered porous structure. Thereafter, carbonized polypyrrole (CPPy) nanowire conductive networks were built up on etched carbon fibers (ECFs) by electrochemical in situ growth and carbonization. Based on the CPPy network, MnO2 nanoflowers were grown firmly by the hydrothermal method to construct multi-layer MnO2@CPPy@ECFs composite electrode. The multi-layered 3D CPPy conductive network is rooted in MnO2, providing a dedicated transmission path for both electrons and ions during electrochemical redox reactions. The MnO2@CPPy@ECFs electrode had an initial capacity of 346.1 mA h·g−1 at 0.1 A g−1 and 252.8 mA h·g−1 after 800 cycles. In addition, the integrated flexible Zn–MnO2 2D fabric battery with MnO2@CPPy@ECFs fabric cathode shows a specific capacity of 254.7 mA h·g−1 at 0.1 A g−1. Finally, a flexible Zn–MnO2 yarn battery with high flexibility, shape adaptability, structural integrity and good mechanical stability was fabricated by the 2D braid method. The initial specific capacity of the flexible Zn–MnO2 yarn battery is 111.7 mA h·g−1 at 0.1C, which also presents a remarkable volumetric energy density of 30.5 mW h cm−3. This work opens up a new pathway for the rational design of flexible electrodes for wearable ZIBs.}, journal={CARBON}, author={Chen, Lei and Hu, Kairui and Yang, Ke and Yanilmaz, Meltem and Han, Xu and Liu, Yong and Zhang, Xiangwu}, year={2023}, month={Nov} }

In recent years, the emergence of wearable electronic devices and smart textiles has placed a new demand on energy storage batteries - flexibility. Carbon materials, namely carbon fibers and several carbon nanomaterials (such as carbon nanotubes, graphene, carbon nanofibers, porous carbon skeletons, and their derivatives) possess remarkable structural and functional adjustability, and are thus well suited for building components of flexible LSBs. These components include current collectors, interlayers, solid electrolytes and anodes. This paper systematically reviews research progress in carbon materials used in different components of flexible LSBs, including the sulfur cathode, interlayer, lithium anode, and dual-functional host carbon materials that can be used as both cathode and anode.

The aim of this study was to design new high-performance separator membranes with superior electrochemical properties such as high C-rate performance and good thermal stability compared to polyolefin based membranes. Uniform, bead-free fibrous structure with high amount of SiO2 nanoparticles exposed on PVDF nanofiber surfaces was observed. It was found that wettability and ionic conductivity were improved by dispersing SiO2 nanoparticles onto PVDF nanofiber surfaces. Electrochemical properties were enhanced due to the increased surface area caused by the unique hybrid structure of SiO2 nanoparticles and PVDF nanofibers. Compared with commercial microporous polyolefin membranes, SiO2/PVDF hybrid membranes had larger liquid electrolyte uptake, higher electrochemical oxidation limit, and lower interfacial resistance with lithium. SiO2/PVDF hybrid membrane separators were assembled into lithium/lithium iron phosphate cells and demonstrated high cell capacities and good cycling performance at room temperature. In addition, cells using SiO2/PVDF hybrid membrane separators showed superior C-rate performance compared to those using commercial microporous PP membrane.}, journal={JOURNAL OF MEMBRANE SCIENCE}, author={Yanilmaz, Meltem and Lu, Yao and Dirican, Mahmut and Fu, Kun and Zhang, Xiangwu}, year={2014}, month={Apr}, pages={57–65} }
