Anion-doped LiFeBO3 cathode material has been successfully synthesized by solid-state method followed heat treatment. Fluorine was used as doping element to improve the conductivity of LiFeBO3 material. Various amount of fluorine are given during preparation to reach optimum electrochemical performance. The structure of anion doped LiFeBO3 are investigated by X-ray diffraction, 7Li magic angle spinning NMR spectroscopy, and Fourier Transform Infrared spectroscopy. Also, the electrochemical test and cyclic voltammetry are performed by galvanostatic charge and discharge test. The result showed that fluorine-doped LiFeBO3 has effectively improved electrochemical performance.
