Fabrication and Characterization of Cu[sub 2]O Nanorod Arrays and Their Electrochemical Performance in Li-Ion Batteries

Abstract

This study is an investigation of the electrochemical performance of nanorods in Li ion battery application. The template-mediated electroplating was applied to fabricate nanorod arrays. The morphological observation shows that the nanorods with 60 nm diam and 450 nm length were grown perpendicularly to the substrate. The cyclic voltammetry sweeping indicates a reversible electrochemical reactivity between nanorods and Li, and cycling tests show that the nanorod arrays exhibit a capacity of after 100 cycles. The high capacity and good cycle retention imply that nanorods are a candidate anode material for rechargeable power source.
