摘要：

A two-step solution-phase synthesis led to LiMn0.75Fe 0.25PO4 nanorods grown on graphene with superior electrical conductivity (see picture; rmGO=reduced mildly oxidized graphene oxide). The nanorod morphology is ideal for fast Li+ diffusion, with the diffusion path along the short radial direction (20-30 nm) of the nanorods. An ultrafast discharge performance for this hybrid cathode material is thus achieved. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
