ABSTRACTBased ABSTRACT Based detailed investigation of great deal of related literatures，the preparation and the application ofthe nanomaterials for energy storage have been reviewed，and the recent development ofcarbon aerogel·nitrides，and oxides for supereapaeiter and LiMn204 and SnCh for lithium battery were explained especially．Following that,doped MnOz was prepared by hydrothermal method, nanostructure was effectively controlled by the doping of vanadium and chromimn,flower-like Ni(OH)2 and NiO used for supercapacitor was synthesized,the composition ofy-MozN and several transition metals Was successfully realized，and the supercapacitsnce ofthe as-prepared material Was observably improved．By using peroxide and salt acetate，carbon aerogel with hi【gh capacitance Was firstly obtained by the ambient pressure drying,and fast and effective approach ofthe preparation of carbon aerogel with high capacitance Was achieved．On the basis of hydrothermal method， LiMn204 and Sn02 for anode material of lithium battery,ZnO and Cul were obtained．The research conclusions provide some 013‘ginal and innovative results，and the major contents Can be summarized as foIlows： The nanoparticles of tcWagonal Ct-Mn02 were obtained from the reaction of potassium chlorate and sulphate manganese，and the morphology was changed into口-Mn02鼬the temperature up to 210℃．Vanadium and chromium ion was doped．ordering a·Mn02 nanoparticles．Stick-sphere-like。fabricated orchid—like and symmetrical radial structure was obtained respectively by the doping of vanadium and chromium．The mechanism for the morphology was also discussed in the article．Owing to the interconnected net structure of the material。the manganese dioxide compound showed good supercapacitance，with the specific capacitance of258 Figafterdoping． Flower·like p-Ni(OH)2 crystals were successfully prepared and a hydrothermal complexing·precipitation process was developed．The morphology
