摘要：
Ta2O5 nanoparticles (NPs) are one of the exemplary anode materials for a lithium-ion battery which undergoes the conversion-type electrochemical reaction with extrinsic pseudocapacitance. Ta2O5 NPs have been synthesized using the ionic liquid–assisted hydrothermal method. The prepared mesoporous Ta2O5 NPs were characterized using XRD, Raman, TEM, and BET surface area analysis. XRD pattern of prepared Ta2O5 NPs exhibited an orthorhombic crystal structure with an average crystallite size of 30 nm. The BET specific surface area and average pore diameter of Ta2O5 NPs were found to be 23.11 m2/g and 21 nm respectively. TEM images showed the particle-like structure with an average particle size of 25 nm. Ta2O5 NPs show excellent performance with a reversible capacity of 190 mAh g−1 even after 150 cycles at C/10 current rate. Therefore, Ta2O5 NPs could be the prospective contestant as a anode material for the lithium-ion battery.
