Abstract

LiFePO4/C composite with carbon core structure was successfully prepared by using araldite as carbon source. The microstructure and morphology of LiFePO4/C composite were confirmed by X-ray diffraction and transmission electron microscopic observation. The experimental results show that this structure is entirely different from carbon coating. The LiFePO4/C composite forms a common core structure in which carbon is used as line core and carbon core is covered by nano-LiFePO4 grains. Moreover, the LiFePO4/C composite exhibits higher tap density of 1.66 g cm− 3, shows higher capacity about 162 mAhg− 1 applied 30 mAg− 1 current, excellent cyclic ability and rate capability about 139 mAhg− 1 applied 700 mAg− 1 current at room temperature.
