چکیده انگلیسی
LiV3O8 thin films with a mixed amorphous–nanocrystalline microstructure were deposited on stainless steel substrates using radio-frequency (RF) magnetron sputtering for the first time. The films exhibited good performance as a cathode material for lithium ion batteries. Results indicate that the film electrodes had a smooth surface and consisted mainly of an amorphous structure containing nanocrystalline zones dispersed within it. Depending on its microstructure, the films delivered an initial discharge capacity as high as 382 mAh/g and exhibited good capacity retention, with discharge capacity of 301 mAh/g after 100 cycles representing a loss rate of 0.21% per cycle.
