Description

LiMn2O4 and Li4Ti5O12 films were deposited on the lithium-ion conductor of Li1.3Al0.3Ti1.7(PO4)3 sintered pellet by spray technique. The effect of annealing temperature, annealing time, Li:Ti and Li:Mn molar ratio on the phase and crystallization of the films were investigated with X-ray diffraction. The LiMn2O4/Li1.3Al0.3Ti1.7(PO4)3/Li4Ti5O12 thin-film lithium-ion battery using Li1.3Al0.3Ti1.7(PO4)3 sintered pellet as both electrolyte and substrate was also studied. The results show that the effect of annealing temperature, annealing time, Li:Ti and Li:Mn molar ratio has great effect on the phase and crystallization of Li4Ti5O12 and LiMn2O4 films deposited on the Li1.3Al0.3Ti1.7(PO4)3 sintered pellet. The optimal Li:Ti and Li:Mn molar ratio for the deposition of Li4Ti5O12 and LiMn2O4 films on Li1.3Al0.3Ti1.7(PO4)3 sintered pellet are 7.2:5 and 1.05:2, respectively. The optimal annealing temperature and time for the deposition of LiMn2O4 film on Li1.3Al0.3Ti1.7(PO4)3 sintered pellet are 650 °C and 10 min. While those for Li4Ti5O12 film are 700 °C and 10 min. The LiMn2O4/Li1.3Al0.3Ti1.7(PO4)3/Li4Ti5O12 thin-film battery offers a working voltage about 2.25 V and can be easily cycled. - Highlights: • LiMn2O4 and Li4Ti5O12 films spray deposited on Li1.3Al0.3Ti1.7(PO4)3 sintered pellet • Film crystal phase depends on the spray solution composition and annealing conditions. • Prepared thin-film lithium-ion battery employs sintered pellet as electrolyte and substrate. • LiMn2O4/Li1.3Al0.3Ti1.7(PO4)3/Li4Ti5O12 thin film battery can be easily cycled
