Abstract

The electrode films fabricated with the Lithium titanate powders have been surface modified with metallic copper by electroplating process. The electrochemical performance of the pristine and copper coated anodes has been investigated by Galvanostatic cell cycling and AC impedance spectroscopy. The copper coated anodes exhibit improved rate capability and cycling performance than those of the pristine anode. An analysis of the charge-discharge capacity values and electrochemical impedance spectroscopy (EIS) measurements reveals that the improved electrochemical performances of the copper coated sample are due to the enhancement of charge transfer reaction.
