Large Scale Process for Low Crystalline MoO₃-Carbon Composite Microspheres Prepared by One-Step Spray Pyrolysis for Anodes in Lithium-Ion Batteries.

ABSTRACT: This paper introduces a large-scale and facile method for synthesizing low crystalline MoO₃/carbon composite microspheres, in which MoO₃ nanocrystals are distributed homogeneously in the amorphous carbon matrix, directly by a one-step spray pyrolysis. The MoO₃/carbon composite microspheres with mean diameters of 0.7 µm were directly formed from one droplet by a series of drying, decomposition, and crystalizing inside the hot-wall reactor within six seconds. The MoO₃/carbon composite microspheres had high specific discharge capacities of 811 mA h g^-1 after 100 cycles, even at a high current density of 1.0 A g^-1 when applied as anode materials for lithium-ion batteries. The MoO₃/carbon composite microspheres had final discharge capacities of 999, 875, 716, and 467 mA h
