Facile one-pot synthesis of self-assembled 3-D flower-like SnO_2 architectures and their electrochemical properties

摘要

In this work, self-assembled 3-D flower-like SnO_2 architectures have been successfully synthesized by one-pot hydrothermal method. The structure and morphology of flower-like SnO_2 architectures were investigated by X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. The electrochemical performance of self-assembled 3-D flower-like SnO_2 architectures was measured by galvanostatic charge/discharge cycling, cyclic voltammetry and electrochemical impedance spectroscopy. As anode materials in lithium ion batteries, the results show that the obtained SnO_2 architectures exhibit high lithium storage.
