Abstract: The mixtures of Al(OH)3 and Mn3O4 with different molar ratios, x[x=n(Al)∶n(Mn+Al)=0, 0.025, 0.050, 0.10, 0.150, 0.20] were prepared by the coprecipitation method. The mixtures were sintered at 700 ℃ after mixed with LiNO3. The XRD and Raman results show that the mixtures are the single phase spinel Li[Mn(Al)]2O4 with Al content, x, between 0 and 0.20. The crystal parameter decreases, the lattice vibration energy increases, the bond of Mn(Al)-O becomes stronger, and the structure stability is enhanced when Al content increases.
