- A plasma pretreated micro-structuring electrode has been studied on fluorine doped tin oxide (FTO) films prepared via ECR-MOCVD system and controlled in laser micro-system as anode layers for lithium-ion batteries. The as-patterned electrodes were characterized by X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy measurements. Field emission scanning electron microscopy and transmission electron microscopy observation revealed the patterning distribution of FTO from 5um to 10um on the patterned copper current collectors. The electrochemical performances were evaluated by using pouch-type cells versus metallic lithium. The patterned thin film anode electrode prepared by a micro-structuring process exhibits a high reversible specific capacity of 1418 mAhg-1 at a current density of 117 mAg-1 and excellent rate capability, even at a high current density of 1000 mAg-1, the reversible capacity was still as high as 1032 mAhg-1. The electrochemical test results show that the micro patterned electrode prepared by the micro-structuring synthesis approach is a promising anode material for lithium-ion batteries.
