|Issue Date:||Dec-2009||Citation:||Xia, H., Yan, F., Lai, M.O., Lu, L., Song, W. (2009-12). Electrochemical properties of BiFeO 3 thin films prepared by pulsed laser deposition.

Structural characterization using X-ray diffraction indicates that the film is polycrystalline with perovskite structure. Morphology characterization by field emission scanning electron microscopy reveals that the film is composed of grains with wide size distribution with a porous structure. Charge/discharge in the potential range between 0.05 and 3 V shows that the reversible capacity of the first charge/discharge cycle at 280 mA/g current density is about 770 mAh/g with high columbic efficiency about 74%. The reversible capacity after 50 cycles remains 50% of its initial capacity. The preliminary results indicated that BiFeO 3 is a promising high capacity anode for lithium-ion batteries. © 2009 World Scientific Publishing Company.||Source Title:||Functional Materials Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/85951||ISSN:||17936047||DOI:||10.1142/S1793604709000740|
