“…The voltage profiles had shapes identical to the shapes of previously reported LFP‖Li cells. 53 The polarizations of the cells during charging increased with increasing current density. At the charging current density of 2C, the increased polarization of the LFP‖bare Li cell did not allow delithiation from the LFP cathode; in contrast, the protected Li suppressed the polarization increase, which enabled the high reversible capacity of 125 mA h g −1 at 2C.…”

“…As shown in Figure d, the relationship between the length-specific capacitance of the CFPP@MnO 2 yarn cathode and the current density can be calculated in terms of the GCD discharge curve. As the current density grows, the specific current tends to gradually decrease and stabilize, and the CFPP@MnO 2 yarn cathode has outstanding stability, with slower capacitance loss at higher current densities. − …”

The practical application of yarn electrode materials has been restricted because of the inherent insulating properties and adverse electrochemical properties of conventional yarns. The aim of the study was to make yarn electrodes with higher specific capacitance and construct a type of yarn-like manganese dioxide (MnO 2 ) electrode. In this work, polyacrylonitrile-wrapped carbon fibers (CFs) core-spun yarn (CFP core spun yarn) was prepared by electrospinning with CF yarn as the base material. The highly conductive yarn (CFPP yarn) was then prepared by depositing polypyrrole nanoparticles by in situ polymerization on top of the CFP cored yarn. Finally, based on CFPP yarn, the CFPP@MnO 2 yarn cathode material was prepared by coating MnO 2 on CFPP yarn by an impregnation coating method. The CFPP@MnO 2 yarn cathode showed outstanding electrochemical performance in the three-electrode system test, maintaining 89.76% of the initial capacity after 100 charge−discharge cycles at a current density of 1 mA cm −1 , which indicates that the CFPP@MnO 2 yarn cathode has outstanding cycling stability. The yarn cell can therefore be used as the cathode electrode for yarn batteries, providing an effective strategy for applications in smart textiles and wearable electronics.

Carbon nanostructures have been of increasing interest since the early 1990s because of their excellent material properties and light weight. Carbon nanofibers (CNFs) synthesized by electrospinning and subsequent thermal treatment are among the more promising nanostructured carbonaceous materials, because many experimental parameters can be modified for the precise manipulation of their morphologies and material properties. Technological advances and understanding of CNFs have expanded rapidly in the last 20 years. In this review, published research on CNFs, from precursors to material properties, is thoroughly reviewed, focusing on structures and properties from the perspective of applications. This review provides important insights that will be of benefit for the design of novel CNFs for widespread applications.
