Applications of nanotechnologies including solgel methods,template methods, discharge of carbon bar, mechanical milling and the like, in the areas of lithium secondary batteries in recent years were reviewed. Using these nanotechnologies, nanomaterials for lithium secondary batteries including cathode, anode and other materials could be prepared. The prepared nano cathode materials including lithium cobalt oxides, lithium nickel oxides, lithium manganese oxides, vanadium oxides. Nano anode materials including carbonaceous materials,carbon nanotubes, tin oxides, metallic anodes. Other nanomaterials include polymer electrolytes and conductive agents. All these kinds of nanomaterials were strikingly better in electrochemical performance than those prepared by traditional methods.Further theoretical researches on nanotechnologies in the area of lithium secondary batteries were needed. With the development of nanotechnologies, micro lithium secondary batteries would come out in the near future.
