Characterization of Sn4P3-Carbon Composite Films for Lithium-Ion Battery Anode Fabricated by Aerosol Deposition.

ABSTRACT: We fabricated tin phosphide-carbon (Sn4P3/C) composite film by aerosol deposition (AD) and investigated its electrochemical performance for a lithium-ion battery anode. Sn4P3/C composite powders prepared by a ball milling was used as raw material and deposited onto a stainless steel substrate to form the composite film via impact consolidation. The Sn4P3/C composite film fabricated by AD showed much better electrochemical performance than the Sn4P3 film without complexing carbon. Although both films showed initial discharge (Li+ extraction) capacities of approximately 1000 mAh g-1, Sn4P3/C films retained higher reversible capacity above 700 mAh g-1 after 100 cycles of charge and discharge processes while the capacity of Sn4P3 film rapidly degraded with cycling. In addition, by controlling
