Abstract

Abstract:

Surface coating has long been an effective means to improve the electrochemical performance of electrode materials for Li-ion batteries. In this study, the traditional micron-sized Li₄Ti₅O₁₂ anodes are coated with amorphous lithium phosphate by radio frequency (RF) magnetron sputtering. The characterized morphology indicates that the electrodes are covered by a thin amorphous lithium phosphate coating layer, showing a very smooth surface. Both the rate performance and cycle performance of the electrodes are enhanced markedly by the coating layer in the voltage range of 0.01-3.00 V. When the discharge-charge currents are 35 and 1750 mA∙g^-1, the capacities are elevated to 265 and 151 mAh∙g^-1, respectively, which are higher than those of the uncoated ones (240 and 22 mAh∙g^-1). After further discharge-charged for 200 cycles at 88 mA∙g^-1, the coated electrodes still maintain a high reversible capacity of 238 mAh∙g^-1. This result clearly suggests that the thin layer can stabilize the solid electrolyte interface, maintain the integrity of the interparticle electronic passage and form a cross-linked ionic conducting network for Li₄Ti₅O₁₂ grains on the surface.

Key words: lithium titanate, amorphous lithium phosphate, anode, lithium-ion battery, magnetron sputtering
