Spherical LiNi_(0。5)Mn_(1。5)O_4 powders were prepared by internal combustion type spray pyrolysis apparatus using gas burner。 The powder production capacity was 1 kg/h by this equipment。 After calcinations of as-prepared powders contained Ni at different temperatures from 800 to 1200℃ in air for 10h， LiNi_(0。5)Mn_(1。5)O_4 powders were obtained。 As-prepared particles have a porous microstructure with an average diameter of about 5 μm with narrow size distribution。 XRD showed that LiNi_(0。5)Mn_(1。5)O_4 powders were well crystallized to a spinel structure with Fd3m space group。 LiNi_(0。5)Mn_(1。5)O_4 powders calcined at 1000℃ show good cycle performance with after 30 cycles discharge capacity of 112mAh/g and 95% retention after 400 cycles between 3。5 V and 5 V。
