• 一般注記: Al doped LiMn2O4 powders were prepared by spray pyrolysis using the aqueous solution of manganese carbonate. The aqueous solution, in which manganese carbonate was uniformly dispersed by a surfactant, was used as the starting solution. Al2O3 nanopowders, Al(OH)3 and Al(NO3)3・9H2O were used as the doping agent of Al. A scanning electron microscope photograph showed that Al doped LiMn2O4 powders had spherical morphology with broad particle size distribution. X-ray diffraction revealed that crystal phase of all samples were good agreement with spinel phase. The rechargeable capacity of Al doped LiMn2O4 cathode was about 110 mAh/g at 1 C regardless of doping agent. 75% of initial discharge capacity was maintained after 100 cycles.
