“…Pure SnO 2 nanofibers show capacity of *780 mAh/g at fiftieth cycle, however, only at a low discharge rate of 0.2C (Hwang et al 2014). A list of literature reports on the synthesis of SnO 2 and SnO 2 -carbon nanofibers employing the electrospinning technique and their electrochemical performance are provided in Table 1 and compared with the present study (Bonino et al 2011;Fu et al 2014;Hwang et al 2014;Jung and Lee 2011;Kim et al 2014;Kong et al 2012;Xia et al 2012;Yang et al 2015;Yang and Lu 2014;Yang et al 2010;Zhou et al 2014). In the present investigation, a facile (Wang et al 2016), inexpensive route for the Synthesis of porous SnO 2 -carbon composite nanofibers with small amount of carbon using electrospinning technique has been developed.…”

“…Park et al demonstrated that morphology also play significant role (Park et al 2008) in electrochemical performance of the electrode. A number of SnO 2 nanostructures with different morphologies have been fabricated such as nanoparticles (Deng and Lee 2008;Reddy et al 2015) nanosheets (Ding et al 2011), nanotubes (Um et al 2015), nanowires (Jiang et al 2009), microspheres (Gurunathan et al 2014) and nanofibers (Hwang et al 2014) to observe better electrochemical performance. Also various forms of carbon such as carbon nanotubes (Elizabeth et al 2015), graphene (Liu et al 2015;Zhang et al 2015), amorphous carbon (Zhou et al 2015) and crystalline carbon (Liu et al 2012) have been used for preparing SnO 2 /carbon composites.…”

High rate capability and cyclic stability of hierarchically porous Tin oxide (IV)–carbon nanofibers as anode in lithium ion batteries

et al. 2017

Tin oxide-carbon composite porous nanofibres exhibiting superior electrochemical performance as lithium ion battery (LIB) anode have been prepared using electrospinning technique. Surface morphology and structural characterizations of the composite material is carried out by techniques such as XRD, FESEM, HR-TEM, XPS, TGA and Raman spectroscopy. FESEM and TEM studies reveal that nanofibers have a uniform diameter of 150-180 nm and contain highly porous outer wall. The carbon content is limited to *10% in the nanofibers as shown by the TGA and EDAX which does not fade the high capacity of SnO 2 . These nanofibers delivered a higher discharge capacity of 722 mAh/g even after 100 cycles at high rate of 1C. The excellent electrochemical performance can be ascribed to the synergy effect of small amount of carbon in the composite and the hierarchically porous structure which accommodate large volume changes associated with Li-ion insertion-desertion. The porous nano-architecture would also provide a short diffusion path for Li ? ions in addition to facilitating high flux of electrolyte percolation through micropores. The electrochemical performance of composite material has also been tested at 60°C at a higher rate of 2C and 5C. Post cycling FESEM analysis shows no volumetric and morphology changes in porous nanofibers after completing rate capability at high rate of 10C.

“…One effective approach to modify the issues is to synthesize 1D porous nanomaterials to accommodate the volume variation. Hwang et al [166] and Yang et al [167] produced porous SnO 2 nanofibers and presented enhanced cycle performance via electrospinning followed by subsequent thermal treatment. In these two works, Hwang et al [166] reported a comprehensive study of fibrous porous SnO 2 nanofibers, which were obtained by calcining the as-spun PVP-SnCl 2 ·2H 2 O nanofibers at 750°C in air.…”

Electrospinning has attracted tremendous attention in the design and preparation of 1D nanostructured electrode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (NIBs), due to the versatility and facility. In this review, we present a comprehensive summary of the development of electrospun electrode nanomaterials for LIBs and NIBs, and a brief introduction about electrode materials beyond LIBs and NIBs. By summarizing various electrochemical active materials, this review focuses on the evolution in structures and the constitution of electrospun electrode materials. In detail, a variety of electrospun anode and cathode materials of LIBs and NIBs have been properly discussed, respectively. Finally, the current progress in the electrospun electrode materials is well reviewed and the development direction is also pointed out. We believe that in the nearly future, electrospun electrode materials would be applied in commercial LIBs and promote the advance in NIBs. And we hope that this review could be helpful in the design and fabrication of electrospun hierarchical materials for other advanced energy-storage devices.

Magnesium-ion conducting gel polymer electrolytes (GPEs) with different contents of nano-sized MgO have been prepared and investigated by various electrical and electrochemical techniques. The Mg 2+ ion conduction in GPEs was confirmed from cyclic voltammetry and impedance analysis. It was found that doping appropriate nano-sized MgO in the GPE can induce significant improvements in both the electrochemical and the mechanical properties of GPEs. The composite GPE with 7% MgO shows a high ionic conductivity of 4.6 × 10 −3 S/cm with electrochemical stability up to 4.7 V versus Mg 2+ /Mg at room temperature. Furthermore, it is free-standing and flexible with high tensile strength (9.7 ± 0.1 MPa) and elongation at break (91.7 ± 0.2%), further ensuring their potential applications as GPEs for rechargeable Mg batteries.
