Synthesis and Electrochemical Performance of a Novel Nano-Sized Sn-Ni Alloy Composites for Lithium Batteries
Abstract:
Two nano-sized Sn-Ni alloy composites are synthesized as anode materials for Li-ion battery through chemical precipitation and hydrothermal method, respectively. The morphology characteristics and electrochemical performance of the materials are investigated. Results show that the Sn-Ni alloy composite prepared by hydrothermal method has a better crystal structure, higher specific capacity and more stable cycling. This material exhibits an initial discharge capacity of 799.1 mAh/g and the column efficiency of 90-94%. This Sn-Ni material shows to be a good candidate anode material for the lithium battery.
