摘要：

Si-SnO composite anode material was synthesized by ball milling approach. To prepare the anode, poly(vinylidene fluoride) (PVdF) and poly(acrlic acid) (PAA) were added as binders, respectively. In contrast to PVdF, PAA buffered large volume expansion of the composite electrode because of its good adhesion strength. So the battery can still maintain a high capacity after few cycles. Cycling test, AC impedance, cyclic voltametry were carried out for investigating electrochemical properties of the composite electrodes. Cycle life and other electrochemical characteristics of the battery were significantly increased by adding PAA.
