  abstract = {<p>Mg<sub>2</sub>Si was synthesized by mechanically activated annealing and evaluated as a negative electrode material. A maximum discharge capacity of 830\&nbsp;mAh/g was observed by cycling over a wide voltage window of 5{\textendash}650\&nbsp;mV versus Li, but capacity fade was rapid. Cycling over the range 50{\textendash}225\&nbsp;mV versus Li produced a stable discharge capacity of approximately 100\&nbsp;mAh/g. X-ray diffraction (XRD) experiments showed that lithium insertion converts Mg<sub>2</sub>Si into Li<sub>2</sub>MgSi after lithium intercalation into Mg<sub>2</sub>Si. Electrochemical evidence of Li{\textendash}Si reactions indicated that the Li<sub>2</sub>MgSi structure can be converted to binary lithium alloys with extensive charging.</p>},
