Electrochemical insertion of lithium in mechanochemically synthesized Zn2SnO4

We studied the electrochemical insertion of Li in mechanochemically prepared Zn2SnO4. The mechanism of the electrochemical reaction was investigated by using X-ray diffraction, nuclear magnetic resonance spectroscopy, and Mossbauer spectroscopy. Changes in the morphology of the Zn2SnO4 particles were studied by in situ scanning electron microscopy. The results were compared with mixtures of SnO2 + ZnO and with Zn2SnO4 prepared by conventional solid-state synthesis and showed that the mechanochemically prepared Zn2SnO4 exhibits the best cyclic stability of these samples.
