“…That is, the capacity of the sample A in this study are higher than those of most SnO 2 with smaller surface areas or larger crystal size if the materials are cycled at the same current density and the same cycle numbers. However, from Table I we can find the performances of the nanorods (cycled at 500 mA g −1 (0.64 C)) 39 and mesoporous spheres SnO 2 (cycled at 1000 mA g −1 (1.28 C)) 41 are better than that of the sample A in this study. There are many factors influence the performance of nanostructures based on particles, 66.14 such as particle size, surface area and pore distribution.…”

Powders composed of SnO2 nanostructures including microporous nanospheres, mesoporous nanospheres and nanosheets were synthesized by the direct hydrothermal hydrolyzation of SnCl4, hydrothermal hydrolyzation of SnCl4 using glucose as a soft template and precipitation of SnCl2 ∙ 2H20 using oxalic acid as a precipitant, respectively. The electrochemical performance of the three samples used as the anode of a lithium ion battery was determined using galvanostatic discharge/charge tests and electrochemical impedance spectroscopy. Among of them, the anode composed of microporous SnO2 nanospheres demonstrated outstanding initial discharge and charge capacities of 2480 and 1510 mAh g-1, respectively, with a coulombic efficiency of 60.9% at a current density of 78 mA g-1 (0.1 C). In addition, high initial discharge and charge capacities of 1398 mAh g-1 and 950 mAh g-1, respectively, with a coulombic efficiency of 67.95% were obtained even at a high current density of 550 mA g-1 (0.7 C). Moreover, a reversible capacity of 500 mAh g-1 with a coulombic efficiency of 99.95% was attained even after 50 discharging/charging cycles at 550 mA g-1 (0.7 C). This superior electrochemical performance of the SnO2 anodes can be attributed to the large specific surface area (172.7 m2 g-1), small crystal size (approximately 15 nm) and the interstitial microporous pores (<2 nm) of the particles, which favored lithium-ion diffusion and insertion/desertion at the surface of SnO2 and decreased the polarization and the volume expansion of SnO2. Moreover, the resistance of the cell and Li+ diffusion coefficient were studied by electrochemical impedance spectroscopy.

“…A valid method is to apply various nanostructures to decrease the internal strain and shorten electronic transport lengths. For example, various nanostructures of SnO 2 with nano-dimensions such as nanowires [22,23], nanotubes [24], nanoparticles [25,26], nanorods [27][28][29][30][31], and hollow nanostructures [32][33][34] are already prepared and confirmed enhanced electrochemical property. Another effective approach is to prepare a tin-based composite oxide material by doping and modification to enhance the structural stability of the material [35][36][37][38][39].…”

Polypyrrole (PPy)-coated tin oxide and silica oxide composite nanomaterials are synthesized by hydrothermal method and electrochemical in situ polymerization. Herein, the effect of PPy contents on the structure and properties of PPy/SnO 2 @ SiO 2 nanocomposites is investigated. With the increase of the pyrrole monomer content, the thickness of the cladding layer of PPy/SnO 2 @SiO 2 core-shell structure increases gradually. And the results indicate that the sample containing 28 wt% PPy exhibits the stable structure of composite and high initial capacity. Moreover, the first discharge capacity reaches 3750 mAh g −1 and its specific capacity can still maintain 676 mAh g −1 after 100 cycles. Owing to this core-shell structure nanomaterial which provides more stable intercalation-deintercalation of lithium channels and sites, PPy coating can inhibit the volumetric expansion of the SnO 2 nanospheres (NPs) electrode effectively. Consideration of the remarkable performance and high initial capacity, PPy/SnO 2 @SiO 2 composite is of keen interest for a potential lithium ion battery anode material.
