摘要
阐述了各种湿化学合成方法的基本原理 ,评述了沉淀法、胶体化学法、水热法及离子交换法等湿化学方法合成锂锰氧化物的研究进展。其中溶胶 凝胶法和Pechini法所得产物的均匀性好 ,比表面积大 ,容量较高 ,但其流程相对较复杂 ;水热法和离子交换法合成锂锰氧化物的研究还处于起步阶段 。
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.
