“…Three peaks appear at about 531.8 eV, 534.0 eV and 531.0 eV in Figure 4 d, which refer to the bonds of C=O, C−O and Sn−O−C, respectively. Figure 4 e shows that three peaks were located at about 401.7 eV, 399.8 eV and 398.5eV, which corresponded to the bonds of graphitic N, pyridinic N and pyrrolic N [ 40 ], respectively. In the high resolution of S 2p, Figure 4 f demonstrates that there were three peaks at around 163.7 eV, 165.2 eV and 168.8 eV, which were assigned to the chemical bond energies of C−S−C, C−S−C and C−SO x [ 41 , 42 ], respectively.…”

As a potential anode material for lithium-ion batteries (LIBs), metal tin shows a high specific capacity. However, its inherent “volume effect” may easily turn tin-based electrode materials into powder and make them fall off in the cycle process, eventually leading to the reduction of the specific capacity, rate and cycle performance of the batteries. Considering the “volume effect” of tin, this study proposes to construct a carbon coating and three-dimensional graphene network to obtain a “double confinement” of metal tin, so as to improve the cycle and rate performance of the composite. This excellent construction can stabilize the tin and prevent its agglomeration during heat treatment and its pulverization during cycling, improving the electrochemical properties of tin-based composites. When the optimized composite material of C@Sn/NSGr-7.5 was used as an anode material in LIB, it maintained a specific capacity of about 667 mAh g−1 after 150 cycles at the current density of 0.1 A g−1 and exhibited a good cycle performance. It also displayed a good rate performance with a capability of 663 mAh g−1, 516 mAh g−1, 389 mAh g−1, 290 mAh g−1, 209 mAh g−1 and 141 mAh g−1 at 0.1 A g−1, 0.2 A g−1, 0.5 A g−1, 1 A g−1, 2 A g−1 and 5 A g−1, respectively. Furthermore, it delivered certain capacitance characteristics, which could improve the specific capacity of the battery. The above results showed that this is an effective method to obtain high-performance tin-based anode materials, which is of great significance for the development of new anode materials for LIBs.

“…By adding more lithium storage sites or enhancing their compatibility with other materials, modifications to CNFs can improve their application performance. The modification methods of CNFs include doping with heteroatoms (such as N, B, or S), coating with metal oxides (such as TiO2, SnO2, or Fe3O4), or compositing with other carbon materials (such as graphene or carbon black) [6].…”

Lithium-ion batteries (LIBs), one of the most promising energy storage methods, have been widely used in portable electronic devices due to their excellent performance, including no memory effect, great safety performance, and high energy density. The performance of the negative electrode, an essential component of LIBs, has a significant impact on the metrics of the battery as a whole. However, LIBs built with traditional electrode materials have limited durability, inadequate energy and power densities, and high prices. The discovery of carbon nanoparticles enables the design of innovative energy storage materials suitable for LIBs. Its large specific surface area, short diffusion distance, high conductivity, and strong ion conductivity are just a few of the numerous distinguishing characteristics that make it a revolutionary form of carbon material. It has a wide range of application possibilities thanks to LIBs with high reversible capacity, high power density, prolonged cycle stability, and superior safety. The most recent developments in one-, two-, and three-dimensional carbon nanomaterials are reviewed in this article, along with their uses in LIBs. The difficulties and potential benefits of creating high-performance LIBs in the future utilizing carbon nanomaterials were highlighted.

“…For example, flexible selfsupporting nanofiber anodes with SiO 2 nanoparticles embedded uniformly were successfully prepared by polyethylene grafting interface modification and electrostatic spinning. 135 Some cathode materials for LIBs have also been prepared and studied, such as, spinel LiNi 0.5 Mn 1.5 O 4 , 136 Ti 3 C 2 , 137 LiV 3 O 8 , 138 BaLi 2 Ti 6 O 14 , 139 SnO x , 140 TiO 2 , 141 etc. However, most of these materials are not fabrics film, but microscopic fibriform materials, which cannot be used as freestanding electrode for flexible/wearable battery.…”

The growing interest in wearable electronics has triggered an enormous demand for flexible/wearable power sources. Flexible batteries, including lithium-ion batteries, Sodium-ion batteries, and Zinc/Zinc-Air batteries have been developed greatly. Nanofiber nonwoven fabrics form highly porous networks with remarkable interconnectivity between their pores, making them play an important role in flexible batteries as separators, current collectors and electrodes, etc. It looks that nanofiber nonwoven fabrics are promising to apply in flexible batteries, thus it is time to summarize their fabrication technology, flexible characteristics, electrochemical performance, and application prospects. This review paper focused on the current application status, emerging developments, and challenges of nanofiber nonwoven fabrics produced by electrospinning on flexible batteries. It is hopeful that this job will provide important references for the flexible batteries industrialization.
