Abstract
The electrochemical reactions of Li with c-Mg2Sn have been investigated by in situ Mössbauer spectroscopy of 119Sn and X-ray diffraction. The lithiation transforms initially c-Mg2Sn part into Li x Mg2Sn alloy (x < 0.5). On further lithiation Mg is extruded from the structure with formation of Li2MgSn ternary alloy. In situ Mössbauer spectroscopy provides valuable information on local environment of tin and swelling behavior and cracking of the particles during discharge and charge processes.
