Zhu, X., Chou, S., Wang, L., Li, Q., Shi, D., Wang, J., Chen, Z., Sun, Y., Liu, H. & Dou, S. Xue. (2009). Self-oriented Ca3Co4O9 thin film as an anode material for enhanced cycling stability of lithium-ion batteries. Electrochemical amd Solid-State Letters, 12 (9), 176-180.


Self-oriented Ca3Co4O9 nanoflake thin film has been prepared by a simple sol–gel method as the anode for thin-film lithium-ion batteries. The X-ray diffraction and transmission electron microscopy results show that the prepared Ca3Co4O9/Pt film is -axis self-oriented and composed of nanoflakes approximately 2ym in diameter and 200–300 nm thick. The reversible lithium storage capacity of the Ca3Co4O9 thin-film electrode at 1 C is around 800mAhg-1 , and it retains more than 70% capacity after 50 cycles, suggesting that the Ca3Co4O9 thin film can be used as the anode for lithium-ion batteries.
