“…To overcome this problem, numerous researchers have focused on silicon-based anode materials because of its high theoretical specific capacity and relatively low charge/discharge voltage. Among them, silica (SiO 2 ), the main institutions of sand and quartz, is generally considered to be a promising candidate [4][5][6][7]. Silica is easier to prepare and is much more economical than silicon, while also stores a large quantity of lithium and has a relatively low potential platform.…”

“…More seriously, silica can form a great deal of irreversible lithium silicates and Li 2 O during the first lithiation cycle. This process consumes an excess amount of cathode materials [6][7][8]13,18,19], which significantly reduces the total energy density of full-cells, thereby preventing their practical applications. In order to tackle this issue, researchers have proposed prelithiation of the electrode material, which directly compensates for the irreversible loss of lithium during the first cycle [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37].…”

Prelithiation is an important strategy used to compensate for lithium loss during the formation of a solid electrolyte interface (SEI) layer and the other irreversible reactions at the first stage of electrochemical cycling. In this paper, we report a systematic study of thermal prelithiation of SiO2 particles with different sizes (6 nm, 20 nm, 300 nm and 3 μm). All four lithiated anodes (LixSi/Li2O composites) show improved performance over pristine SiO2. More interestingly, lithiated product from micron-sized SiO2 particle demonstrates optimum performance with a charge capacity of 1859 mAhg−1 initially and maintains above 1300 mAhg−1 for over 50 cycles.

“…The FS method is the trade name of the centrifugal spinning method that has been recently used to produce fibers for energy storage [30][31][32][33][34] and biomedical applications [35] .The centrifugal spinning process was originally developed and used by Hopper in 1924 to produce artificial silk threads from viscose or equivalent substances by applying centrifugal forces to a viscous material [36] and was extensively used to produce fibers in nano/micro range [37]. The centrifugal spinning method has been recently used to produce polymer nanofibers after the pioneer work reported by Weitz et al on the unexpected formation of nanofibers, with diameters in the nanometer range, from polymer solution using a standard spin-coating process [38].…”

The development of alternative anode materials out of flexible composite nanofibers has seen a growing interest. In this paper, binary carbon nanofiber electrodes of SnO 2 /NiO and Sn nanoparticles are produced using a scalable technique, Forcespinning (FS), and subsequent thermal treatment (carbonization). The Sn/C composite nanofibers were porous and flexible, while the SnO 2 /NiO composite nanofibers had "hairy-like" particles and pores on the fiber strands. The nanofiber preparation process involved the FS of Sn/PAN and SnO 2 /NiO/PAN solution precursors into nanofibers and subsequent stabilization in air at 280°C and calcination at 800 o C under an inert atmosphere. The flexible composite nanofibers were directly used as working electrodes in lithium-ion batteries without a current collector, conducting additives, or binder. The electrochemical performance of the SnO 2 /NiO/C and Sn/C composite fiber anodes showed a comparable cycle performance of about 675 mAhg -1 after 100 cycles. However, the SnO 2 /NiO/C electrode exhibited a better rate performance than the Sn/C composite anode and was able to recover its capacity after charging with a higher current density. A postmortem analysis of the composite nanofiber electrode after the aging process revealed a heavily passivated electrode from the electrolyte decomposition by-products. The synthesis and

“…This method permits the use of a larger number of polymers and composites solutions with higher concentrations to be utilized with a reduced production cost due to the use of less solvent, fast fiber production rate (1 g min −1 ) because there is no need to apply an electric field to stretch the fibers . Many polymer nanofibers such as: poly(ethylene oxide), polypropylene, polyvinylpyrrolidone, poly‐ l ‐lactic acid, polyacrylonitrile (PAN) and PAN nanocomposites, poly(ε‐caprolactone), cellulose acetate, and poly(ethylene terephthalate) have been successfully produced by CFs for use in different applications such as energy storage, filtration, and tissue scaffolding. Polymer nanofibers have also been used for antimicrobial applications.…”

The production of poly(acrylic acid) (PAA) nanofibers by the centrifugal spinning of PAA solutions in water is reported. The effect of the spinneret rotational speed and concentration of PAA solutions on the diameter of nanofibers and on their quality (assessed by the absence of beads) is discussed. The main physical properties of PAA such as glass‐transition temperature (Tg) are studied in detail and compared to the feature of the as‐received homopolymer. It is shown that the glass‐transition temperature of the bulk PAA and PAA nanofibers (as measured by differential scanning calorimetry) depends on the heating rate according to a Williams–Landel–Ferry‐like equation. Raman spectroscopy data provided additional information about the differences between the as‐received polymer and the nanofibers. Preliminary results on antibacterial properties of the PAA nanofibers are reported. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47480.
