![]() TiO2 particle were produced from titanium isopropoxide sol by hydrothermal processing. 5 H2O in the presence of titania nanoparticle after drying and calcinations treatments. SnO2/C-1.0 microspheres (the mass ratio of soluble starch to SnCl4♵H2O is 1:1) with good spherical shape and 34. The strategy gives a rational avenue to design the oxide anodes with efficient hierarchical structure for LIB development. Tools Share Abstract The particles of TiO2 core/ SnO2 shell nanocomposite were prepared by hydrolysis of SnCl4. When evaluated as LIB anode, it demonstrates an initial reversible capacity of 1170.5 mAh g −1 at 0.1 C, maintaining a high capacity of 441.5 mAh g −1 after 1200 stable cycles at high rate of 2 C. We initially utilized cost-effective SnCl45H2O as the starting precursor in. 1.54 g SnCl45H2O was added to 10 ml ethylene glycol solution to form a homogeneous solution by slow stirring for 40 min. Such hierarchical structure provides sufficient ion/electron ingress/transport channels, restrains the adverse reaction of the electrolyte, improves the conductivity and buffers the interior stress of the entire electrode, resulting in the stable cycle performance.

In the well-designed architecture, amorphous carbon coated ultrafine SnO 2 nanoparticles are aggregated into regular microspheres and wrapped by a PEDOT : PSS layer, forming a robust core-shell structure with dual protection layers. Herein, core-shell structured SnO microspheres are synthesized through a facile approach combined with hydrothermal treatment and polymerization. In the presence of air, stannous oxide burns to form the dioxide, or stannic oxide, SnO2, a white insoluble solid. Rational structural design can mitigate the volume expansion of SnO 2, improving the structural stability and reaction kinetics at the same time. Yet, the achieved capacity is restricted by the severe cycling degradation. Abundant material SnO 2 is considered as a promising lithium-ion battery (LIB) anode candidate due to its high theoretical capacity.
