“…5,6 Among those metal oxides, tin dioxide has attracted particular interest because of its high capacity (781 mAh/g). 6 Nevertheless, practical implementation of SnO 2 in lithium-ion batteries is greatly frustrated by the large initial irreversible capacity induced by Li 2 O formation and the abrupt capacity fading caused by volume variation (up to 258% 7 ). Myriad charge transport and electronic conduction issues 8 have been attributed to these factors, and they have turned out to be major obstacles that militate against any practical use of SnO 2 .…”

“…Generally, carbonaceous materials can be the most effective candidates among the "buffering" matrices because of their good conductivity, Li þ permeability, and chemical compatibility with tin oxide, the Li-Sn alloys, and the electrochemical system. 7 Another alternative strategy [9][10][11] is to prepare tin oxide in the form of nanostructured materials, especially one-dimensional nanomaterials, because of their adequate potential to enhance kinetic properties owing to their large surface area and short Li þ diffusion length from a structural viewpoint. 8 Therefore, viable SnO 2 -based electrode materials mainly involve composite materials 12 and nanomaterials such as nanotubes, 5,[13][14][15] nanowires, [16][17][18][19] hollow spheres, 20 mesoporous structures, 21 etc.…”

SnO2@carbon nanofibers were synthesized by a combination of electrospinning and subsequent thermal treatments in air and then in argon to demonstrate their potential use as an anode material in lithium ion battery applications. The as-prepared SnO2@carbon nanofibers consist of SnO2 anoparticles/nanocrystals encapsulated in a carbon matrix and contain many mesopores. Because of the charge pathways, both for the electrons and the lithium ions, and the buffering function provided by both the carbon encapsulating the SnO2 nanoparticles and the mesopores, which tends to alleviate the volumetric effects during the charge/ discharge cycles, the nanofibers display a greatly improved reversible capacity of 420 mAh/g after 100 cycles at a constant current of 100 mA/g, and a sharply enhanced reversible capacity at higher rates (0.5, 1, and 2 C) compared with pure SnO2 nanofibers, which makes it a promising anode material for lithium ion batteries.

TiO 2 (B)@SnO 2 core-shell hybrid nanowires have been synthesized by a facile hydrothermal process and subsequent liquid phase reaction. Hybrid nanowire electrodes exhibit excellent reversible lithium storage capacity rate capability and good cyclability, mainly due to the particular architecture of the composite, which features an open continuous channel along its axis, facilitating lithium ion diffusion, and provides effective mechanical support for the TiO 2 (B) core, alleviating the stress produced during discharge-charge cycling and also preventing the pulverization of the Sn nanoparticles. Owing to its superior electrochemical performance, this composite could be a promising potential anode material for lithium ion batteries.

“…Also, the ability of carbon materials to reversibly insert lithium contributes positively to the overall reversible capacity. In fact, Sn-TM-C composites are more efficient than their individual components taken separately [14]. In this context, disordered carbons prepared at low temperatures, such as coke, may play an important role.…”

Sn-Co-C composites were prepared by carbothermal reaction of ball-milled precursors. X-ray diffraction and 119 Sn Mössbauer spectroscopy of the original composites revealed the predominance of Sn and CoSn 2 phases for those samples prepared with a high Sn/Co ratio. Electron microscopy images showed a homogeneous dispersion of sub-micrometric metallic particles in the carbon matrix. Galvanostatic cycling at several kinetic rates revealed that Sn 7 Co 1 C 92 and Sn 8 Co 4 C 88 are able to maintain 400 mA h g −1 after 40 cycles at 35 mA g −1 . The large CoSn 2 contribution revealed by Mössbauer spectroscopy in the original and cycled electrodes is responsible for the good electrochemical performance. This interpretation is also supported by impedance spectroscopy measurements.
