Mesoporous LiFePO4 cathode material resembling the structure of Swiss-cheese was prepared by a one-pot reaction using hydrophilic carbon nanoparticles (20-30 nm) as the template. The LiFePO4 has submicron-sized particles with a bimodal mesopore size distribution centered at 2.9 and 30 nm. The introduction of mesopore is good for the electrolyte flooding and Lip>+p> diffusion. The 3.8%remaining carbon in the mesopore ensures the complete reduction of Fep>3 +p>. It exhibits a high discharge capacity of 137 mAh/g at 1 C. After high rate charge and discharge at 30 C (one full discharge in 2 min) its capacity can be recovered to 160 mAh/g.
