摘要：

We present a single crystalline Ge nanowire anode material sheathed with carbon prepared by a solid-liquid solution method. The composite electrode composed of Ge nanowires shows impressive electrochemical properties, exhibiting a very high reversible charge capacity (after lithium removal) of 963 mA h g(-1) with a coulombic efficiency of 91%.
