Abstract
Through sol–gel processing and electrospinning technique, extrathin fibers of poly(vinyl alcohol) (PVA)/lithium chloride/manganese acetate composite fibers were prepared. After calcination of the above precursor fibers at 600 °C, the spinel lithium manganese oxide (LiMn 2O 4) nanofibers, with a diameter of 100–200 nm, were successfully obtained. The fibers were investigated by TG–DTA, XRD, FT-IR, and SEM, respectively. The results showed that the crystalline phase and morphology of the fibers were largely influenced by the calcination temperature.
