ELECTROCHEMICAL PROPERTIES OF FE-DOPING LI4TI5O12 AS ANODE MATERILAL FOR LITHIUM ION BATTERY
Li4Ti5O12 and Li4-x/3FexTi5-2x/3O12 were synthesized by sol-gel method.Material structure,morphology and electrochemical performance were characterization.The result showed that after doping copper ions,crystal shape and particle size were all changed.The electrochemical properties of active material were improved as the particle size of the pure sample after doping.Compared to pure phase,Li4-x/3FexTi5-2x/3O12 had better discharge specific capacity and cycle stability at high rate capability.
