Abstract

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.
