Spherical porous Mn_2O_3 powders were prepared by spray pyrolysis. Li and Al nitrate solution were immersed to porous Mn_2O_3 powders to obtain LiAl_xMn_(2-x)O_4. Homogeneous LiAl_xMn_(2-x)O_4 powders were formed by the calcination at 800℃. SEM observation showed that they had spherical morphology with particle size of about 1μm. XRD revealed that the spinel phase was obtained by heating at 800℃. LiAl_xMn_(2-x)O_4 cathode obtained by this method exhibited higher rechargeable capacity and cycle stability than that obtained by spray pyrolysis. The doping of Al ion was effective for the cycle stability at elevated temperature.
