electrchemical experiments were performed using CR2032-type coin cell. For preparing working electrodes, a dispersant of the as-synthesized hybrid materials, carbon black, and poly(vinyl difluoride) (PVDF) at a weight ratio of pure AL foil. Typical loadings for the 50 m-thick coatings were 5 mg*cm-2 of cathode powder. Microporous polypropylene separator (Celegard 2400) was used as a separator. The electrolyte consisted of a solution of 1 mol/L LiPF6 in ethylene carbonate (eC)/dimethyl carbonate(DMC)(1:1. In volume) obtained from Vovolyte Chemical Co. Ltd. Pure lithium foil was used as a counter electrode. The cells were assembled in an argon-filled glove-box. Galvanostatic charge-discharge cycles were tested by LAND CT2001A multi channel battery testers at various current densities from 1 to 50 C (1 C= 165 mAh/g) between 4.2 and 2.5 V vs Li*/Li at room temperature. Note that under the test-voltage-range conditions, CNTs or pyrolysis carbon is table and does not react with lithium, nonetheless we include the mass of residual carbon when calculating the specific capacity of CNTs hybrid LiFePO4 material samples by a four-point d.c. method. Four-point conductivity measurements were made on discs of 8 mm diameter and 0.6 mm thickness, and a SZT-2 instrument (Suzhou, China) was used. AC impedance spectrum was measured by a Solatron 1260/1287 Impedance Analyzer in the frequency range from 10 mHz to 100 KHz with a potential perturbation at 10mV
