Hard carbon anode containing boron atoms for lithium ion batteries was synthesized by adding boric acid in the pre-carbonized precursor of phenolic epocy resin. The micro-structures of materials were characterized by X-ray diffraction, scanning electron microscope and other technical means. The pore characteristics and specific surface areas were determined in nitrogen absorption method. The electrochemical performance of anode was analyzed by cyclic voltammetry, electrochemical impedance spectra and galvanostatic charge and discharge experiments.The results show that the layer distances, specific surface area, pore volume and initial irreversible specific capacities decrease and the initial coulombic efficiency increases with the increase of the content of boric acid. The reversible capacity increases from 332.2 mAh·g-1 to 461.1 mAh·g-1 and the corresponding resistance of solid inter-phase film decreases from 33.86 Ω to 24.53 Ω when the doping content of boric acid reaches 10%.
