Electrodeposition of SnSb and Sn Nanostructures as Anode Materials of Lithium-Ion Batteries

摘要

Recently the lithium alloy has been extensively investigated as a possible replacement for carbon anode in lithium-ion batteries.Compared with theoretical capacity of graphite (LiC_6,372 mAh g~(-1)),the lithium alloys,such as Li_(4.4)Sn (780 mAh g~(-1)),can deliver a larger capacity than that of graphite.However,a large volume expansion of Li-Sn alloy resulted in capacity losses and low cycleability.
