Electrochemistry of LiV[sub 3]O[sub 8] Nanoparticles Made by Flame Spray Pyrolysis

LiV 3 O 8 nanoparticles (primary particles with ca. 50 nm diameter) have been synthesized by flame spray pyrolysis (FSP). The powder was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and galvanostatic cycling. The initial discharge capacity of the LiV 3 O 8 nanoparticles is 271 mAh g − 1 when discharged from its open-circuit potential to 2.0 V vs Li / Li + at a specific current of 100 mA g − 1 under ambient conditions. The nanoparticles retained a specific discharge capacity of 180 mAh g − 1 beyond 50 cycles. This paper describes the synthesis route as well as the characterizations of the FSP-produced LiV 3 O 8 nanoparticles.
