A two‐step solution‐phase synthesis led to LiMn 0.75 Fe 0.25 PO 4 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.
