Synthesis mechanism of new morphology LiMnPO sub(4) nanofibers using electrospinning process

Lithium manganese phosphate (LiMnPO sub(4)) porous hollow nanofibers have been obtained by electrospinning method with LiNO sub(3), Mn(NO sub(3)) sub(2) times 4H sub(2)O, and NH sub(4)H sub(2)PO sub(4) as starting materials. The results show that the external diameter of the LiMnPO sub(4) hollow nanofibers was in the range of 500-800 nm and the internal diameter was in the range of 50-500 nm at 750 degree C for 5 h in N sub(2) atmosphere. The porous hollow nanofibers obtained were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM). The results show that fibers with porous and hollow morphology were successfully formed by controlling the electrospinning parameters and calcination temperature. It is to be easy of uniform distribution of PVP and make hollow structure.
