Thin-film lithium-ion battery of LiMn2O4/Li1.3Al0.3Ti1.7(PO4)3/LiMn2O4 was fabricated using Li1.3Al0.3Ti1.7(PO4)3 sintered pellet as both substrate and electrolyte. Li1.3Al0.3Ti1.7(PO4)3 sintered pellet was prepared by sol-gel technique, and the thin-film battery was heat-treated by rapid thermal annealing. Phase identification, morphology and electrochemical properties of the components and thin-film battery were investigated by X-ray diffractometry, scanning electron microscopy, electrochemical impedance spectroscopy and galvanostatic charge-discharge experiments. The results show that Li1.3Al0.3Ti1.7(PO4)3 possesses a electrochemical window of 2.4 V and an ionic conductivity of 1.2×10-4 S/cm. With Li1.3Al0.3Ti1.7(PO4)3 sintered pellet as both substrate and solid electrolyte, the fabricated thin-film battery with an open circuit voltage of 1.2V can be easily cycled.
