Methods of fabricating one-dimensional composite nanofiber on a template
membrane with porous array by chemical or physical process are disclosed.
The whole procedures are established under a base concept of "secondary
template". First of all, tubular first nanofibers are grown up in the
pores of the template membrane. Next, by using the hollow first
nanofibers as the secondary templates, second nanofibers are produced
therein. Finally, the template membrane is removed to obtain composite
nanofibers. Showing superior performance in weight energy density,
current discharge efficiency and irreversible capacity, the composite
nanofibers are applied to extensive scopes like thin-film battery,
hydrogen storage, molecular sieving, biosensor and catalyst support in
addition to applications in lithium batteries.
