Abstract


Polyacene(PAS)/carbon and acetylene black(AB)/carbon coated lithium cobalt phosphate composites were synthesized via the solid state reaction method using co-precipitated Co3(PO4)2·8H2O and Li3PO4 mixture as its precursor. X-ray powder diffraction (XRD) was performed to investigate the structure and phase of all the samples. The transmission electron microscopy (TEM) shows that the double carbon layers coated on the surface of LiCoPO4 successfully. The LiCoPO4/C, LiCoPO4/PAS and LiCoPO4/AB delivered a capacity of T 120.92, 121.07 and 138.06 mAh×g-1 at 0.1C, respectively. The double carbon coated LiCoPO4 electrode delivered an initial discharge capacity of 147.12, 143.51 mAh×g-1 after AB/glucose, PAS/glucose coating, which maintained at 59.5% and 61.7% after 15 cycles at the 0.1C rate, respectively.
