Abstract

Vapor Grown Carbon Fiber (VGCF)-core@LiMn_0.4Fe_0.6PO₄-sheath heterostructure nanowire was successfully fabricated by an electrospinning method for high rate Li-ion batteries. The fabricated heterostructure has both the electronic conduction path (VGCF-core) and large reaction surface area with high crystallinity (LiMn_0.4Fe_0.6PO₄-sheath), which enables the high charge–discharge rate capability.
