A spinel type Li x Mn 2O 4 compound was synthesized by rheologic phase reaction using LiNO 3 and electrolytic MnO 2(EMD) as raw materials and mixture solution of water and organic agent with hydroxy as dispersant. The changes in the crystal structure and the reaction mechanism of LiNO 3 and EMD were detected by means of X ray diffraction and thermal analysis (TG DTA). The results show that perfect spinel Li x Mn 2O 4 crystals can be obtained at the calcinating temperature of 760 ℃ for 12 h. It should be noted that there exist two step lithium ...
