Development of wet-chemical synthesis of lithium manganese oxide

The fundamental principle of various kinds of wet chemical methods was described. The development of the synthesis of lithium manganese oxides by wet chemical methods such as precipitation method, sol gel method, Pechini process,hydro thermal synthesis and ion exchange process were reviewed. The Li Mn O materials prepared by sol gel and Pechini processes had well homogeneous, large specific surface area and high capacity. But the process was comparatively complicated. Although hydro thermal and ion exchange synthesis for Li Mn O materials were on the starting stage, it stood for a bright future of one step reacting synthesis for Li Mn O materials.
