title: Chemical synthesis of porous hierarchical Ge-Sn binary composites using metathesis reaction for rechargeable Li-ion batteries.
abstract: Direct metathesis reaction between Mg2Ge and SnCl4 is introduced to prepare porous hierarchical Ge-Sn binary composites, in which the Ge and Sn components are distributed uniformly, with a tap density of 2.3 g cm(-3). As an anode for LIBs, the Ge-Sn composite displays a specific capacity of 980 mA h g(-1) at 0.5 A g(-1) after 250 cycles, and 890 mA h g(-1) at 3 A g(-1) over 1700 cycles. When paired with a commercial LiCoO2 cathode, a 3.6 V full battery with a capacity of 830 mA h g(-1) is obtained.
