Abstract
In this work tin-cobalt-carbon alloy was prepared by high energy ball milling and Cu foil was treated by electro-deposition method. The results show that alloy materials coated on surface-treated Cu foil display high discharge capacity and cycling performance than those coated on original Cu foil because of improved contact ability and buffer effect on large volume changes of alloy materials. After 50 cycles the alloy materials coated on surface-treated Cu foil retain discharge capacity of 450 mAh/g.
