LiMn1−xFexPO4 Nanorods Grown on Graphene Sheets for Ultrahigh‐Rate‐Performance Lithium Ion Batteries

A two-step solution-phase synthesis led to LiMn0.75Fe0.25PO4 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. Detailed facts of importance to specialist readers are published as "Supporting Information".
