Large-Scale Synthesis and Electrochemical Properties of LiAl_XMn_2-XO₄ Powders by Internal Combustion Type Spray Pyrolysis Apparatus Using Gas Burner

Abstract:

Spherical LiAlxMn2-xO4 fine powders were continuously produced by Internal Combustion Type Spray Pyrolysis Apparatus Using Gas Burner from metal nitrate precursor solutions. XRD showed that LiAlxMn2-xO4 powders were well crystallized in a spinel structure with the Fd3m space group. As-prepared powders have a spherical particle shape with a diameter of 2.3 μm. As-prepared samples were calcined at 800 for 10 h in air. The charge/discharge capacity of LiAlxMn2-xO4 was over 100 mAh/g. A powder production capacity speed of 1 kg/h was attained by this system.
