Abstract:

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.
