摘要：

A novel method to modify the surfaces of transition metal oxides (MO) film-electrode was proposed in this study. At first, a monolayer of terephthalic acid was covalently bonded to the surfaces Of Cu2O films. Then silver (Ag) particles were electrodeposited on the monolayer-grafted films by a potential-step process. The resulting Ag-Cu2O films exhibited improved electrochemical performance as negative electrodes in lithium-ion batteries compared to the original Cu2O films. An increase in electrical contact between Cu2O particles was considered to be responsible for the improvement in the electrochemical properties. (c) 2008 Elsevier Ltd. All rights reserved.
