主　　题：lithium ion battery LiFePO4 bromine doping 

摘      要：The olivine-typed cathode material of Li Fe PO4 was prepared via sol-gel method,and the bromine was doped into Li Fe *** crystal structure,morphology,and electrochemical properties of the samples were investigated by X-ray diffraction,scanning electron microscopy and charge–discharge cycle *** results showed that the electrochemical performance of Li Fe PO4 had been improved by bromine doping,and the best doping amount of bromine is 2%.The discharge capacity of this sample can reach 152 m Ah/g at 0.2 C.
