Highly uniform films of pure electrodeposited Cu2O in variable particle size (micronic and submicronic), morphology, and thickness (0.3- 13 mu m) depending on the applied potential and the amount of electrical charge transferred were examined as working electrodes in lithium cells to check their suitability as anodes for Li-ion cells. The thinnest film studied delivered a specific capacity close to the theoretical value; such a capacity decreased with increasing film thickness and particle size. All films except the thickest exhibited excellent capacity retention upon extensive cycling irrespective of particle size. On similar thickness, the discharge capacity increased with decreasing particle size. (C) 2005 The Electrochemical Society.
