Title of Paper:

The improved electrochemical performance of SnSb-based alloy anode materials for Li-ion batteries

Journal:

Journal of Alloys and Compounds

Summary:

ABSTRACT: Nano-sized SnSb alloy anodes were prepared by reductive co-precipitation method combining with the
aging treatment in water bath at 80 ◦C. The microstructure, morphology and electrochemical properties
of synthesized SnSb alloy powders were evaluated by X-ray diffraction (XRD), field-emission scanning
electron microscopy (FE-SEM) and galvanostatical cycling tests. The results indicated that the cycling
performance of SnSb alloy anodes could be improved through reducing particle size.However, the capacity
declinewas still apparent in every cycle due to the poor reversible process of high voltage reaction. When
the cut-off potentialwas limited between 0.02 and 0.9 V, the volume and structure changes are alleviated
effectively and the excellent cycling performance was obtained within 20 cycles.
