一般注記Spherical porous Mn2O3 powders were prepared by spray pyrolysis. Lithium and aluminum nitrate solution were immersed to porous Mn2O3 powders to obtain LiAlXMn2-XO4 powders. Homogeneous LiAlXMn2-XO4 powders were formed by the calcination at 800°C. SEM observation showed that they had spherical morphology with dense microstructure. XRD revealed that the spinel phase was formed by the calcination at 700°C. LiAlXMn2-XO4 cathode obtained by this method exhibited higher rechargeable capacity and cycle stability than that of LiMn2O4. The rechargeable capacity of LiAl0.05Mn1.95O4 exhibited 120mAh/g at 1C and 90mAh/g at 10C, respectively. 91% of initial discharge capacity was maintained after 500 cycles at a rate of 1C. The doping of aluminum ion was effective for the cycle stability of LiMn2O4 cathode at 50°C.
