Budding willow branches shaped Na3V2(PO4)3/C nanofibers were successfully synthesized by a simple electrospinning technique with Poly(vinyl pyrrilidone) (PVP). The Na3V2(PO4)3/C nanoparticles that anchored on the nanofibers surface seemed like the willow buds; the inner core of the nanofibers, which composed Na3V2(PO4)3, looked like willow twig and the uniform carbon layer was same with willow bark...
