Abstract

The olivine-typed cathode material of LiFePO₄ was prepared via sol-gel method, and the bromine was doped into LiFePO₄. The crystal structure, morphology, and electrochemical properties of the samples were investigated by X-ray diffraction, scanning electron microscopy and charge-discharge cycle measurements. The results showed that the electrochemical performance of LiFePO₄ had been improved by bromine doping, and the best doping amount of bromine is 2%. The discharge capacity of this sample can reach 152 mAh/g at 0.2 C.
