One-dimensional(1-D) nanomaterials with superior specific capacity, higher rate capability, better cycling peroperties have demonstrated significant advantages for high-performance Li-ion batteries and supercapacitors. This review describes some recent developments on the rechargeable electrodes by using 1-D nanomaterials(such as Li Mn_2O_4 nanowires, carbon nanofibers, Ni Mo O_4 · n H_2O nanorods, V_2O_5 nanoribbons,carbon nanotubes, etc.). New preparation methods and superior electrochemical properties of the 1-D nanomaterials including carbon nanotube(CNT), some oxides, transition metal compounds and polymers, and their composites are emphatically introduced. The VGCF/Li Fe PO_4/C triaxial nanowire cathodes for Li-ion battery present a positive cycling performance without any degradation in almost theoretical capacity(160 m Ah/g).The Si nanowire anodes for Li-ion battery show the highest known theoretical charge capacity(4277 m Ah/g),that is about 11 times lager than that of the commercial graphite(~372 m Ah/g). The SWCNT/Ni foam electrodes for supercapacitor display small equivalent series resistance(ESR, 52 m?) and impressive high power density(20 k W/kg). The advantages and challenges associated with the application of these materials for energy conversion and storage devices are highlighted.
