Characterization of nanostructure tin alloys as anodes in lithium - ion Batteries

摘要

Several tin-antimony nano-structure alloys were electroplated from an acid bath on a copper foil. They have been characterized as potential high capacity anodes for lithium-ion battery applications. SEM micrographs of these alloys reveal nano - size particle, which aggregate into larger agglomerates of fractal shapes. The composition of one series of alloys was Sn:Sb atoic ratio 1.4:1 to 9:1; another alloy consisted of Sn:Sb:Cu in atomic ratio 34:10:4. all contained about 5
